The Truth About Backend Keyword Search Indexing on Amazon

Is there really a hard limit on Amazon listing “backend” search terms? Anthony Lee has the definitive answer on limits and a lot more.

This post is by Anthony Lee, COO of SixLeaf (formerly ZonBlast), the first and largest product launch and ranking service for Amazon sellers.

If you sell on Amazon, particularly if you sell your own brands, you’ve undoubtedly been affected by the most recent change in the indexing of your listings’ search terms (commonly referred to as “hidden” or “backend” keywords).

Backend keywords are set in Seller Central, and don’t show visibly to buyers. In theory, they should lead to your product appearing in search results, just like the other words in your listing, such as those in the title and description (much more on that later).

However, there has been recent debate about how these terms are included in Amazon’s search index. How many are actually used when deciding whether your product is relevant to a customer’s search?

Anecdotes are rampant across forums and seller groups, telling tales of woe about decreasing listing views.The general consensus is that the number of search term characters that are indexed has decreased dramatically.

But there has been no official update from Amazon, or statements to explain how sellers should now optimize their keywords. Instead, there’s just a lot of the same ambiguous and inaccurate advice. To make matters worse, in typical Seller Central fashion, Amazon’s own support staff are giving out old information, or apparently just making it up as they go.

For this post, we’ve researched how Amazon really indexes backend keywords. I’ll put the record straight on a number of points, so you can make the best use of search keywords in your own listings.

What is being said?

When this story first “broke” there were claims of tests being run that showed a limit of 400 indexed characters, in total across the title and search terms. Later, individual reports claimed a limit of 250 indexed characters in the search terms alone.

From there, some sellers reported that not only were they limited to 250 indexed characters, but any attempt to enter more would result in ALL keywords being removed from the search index. A few messages came out of Seller Support backing up this claim.

On top of that, Seller Support agents reportedly told sellers that repetition from the title and bullets in the search terms was NOT necessary. They also claimed that the description text was no longer being indexed. We have been unable to verify any of these reports.

Why the false information?

The curious part about all this misinformation is that the tools exist for anyone and everyone to test the search indexing of multiple listings in multiple categories, and not just their own. That is precisely what we did.

First, we used ExpertsRoundup (now AmzDataStudio) to scrape backend search terms. This service says it can find the exact search terms for any Amazon listing. We do not know how it achieves this goal, whether it violates any terms, or whether it will continue to operate in the future. But we have used it and discovered that the results are accurate. [Ed: AmzDataStudio was included in a recent Web Retailer article Amazon keyword tools.]

Here’s a sample:

The only way to prove accuracy would be to display a screenshot of every listing’s backend search terms alongside the ExpertsRoundup results – which you can only do for your own account of course. However, we found it to be accurate with our own listings, and no less than a dozen sellers we know confirmed its accuracy. That is still only anecdotal evidence, but accuracy testing at this stage is actually not necessary. You’ll see in a moment.

The next tool we used was a Chrome extension simply called KW Index Checker. This tool, when loaded with an ASIN and search terms, reveals which terms are indexed and which are not.

This CAN be checked for accuracy. By searching on Amazon for the ASIN plus each keyword, we can confirm if the tool has accurately identified indexed terms. If the result says zero listings were found, this means the listing wasn’t indexed for that term. If it says there is one result, the listing was indexed.

In this example, the tool is saying that the keywords “men” and “de” are included in the search index for ASIN B0136PR5TO:

By searching for “B0136PR5TO de” and “B0136PR5TO men” (without the quotes) we could confirm it was accurate:

In the next example, the tool is saying that the keywords “comfort” and “latex” are NOT included in the search index for that same ASIN:

By searching for “B0136PR5TO comfort” and “B0136PR5TO latex”, we can confirm the tool’s accuracy again, when Amazon itself yields no search results.

Our experiment

We did not check every keyword for every listing to confirm these tools’ accuracy (that would have taken WAY too long), but we did check at least a dozen listings to give us a sense that they were serving us with usable data.

Then we ran the ExpertsRoundup search term scraper for a small sample of 40 ASINs. All the ASINs were ranked on page one for relatively competitive key phrases. We attempted to single out what appeared to be highly-optimized private label listings, because useful data would only come from listings with backend search terms in excess of 400 characters (to test the claimed limits).

After the ASINs were scraped, we ran the results through a character counter, to identify listings with over 400 characters of backend search terms. 18 of the 40 listings fell into that category. From there we took the listings and ran their search terms through the KW Index Checker extension, to find which terms were indexed and which were not.

Finally, with the data on indexed and non-indexed search terms, we ran the character counter to find where the limit really was. The ASINs we checked spanned multiple categories, so we also noted any inconsistencies between the categories.

What are the real limits?

The first thing we noted in our experiment was that there was most certainly NOT a hard 250 character limit on indexed search terms. In fact, of all the ASINs that had over 400 characters of search terms, none appeared to be confined to a 250 character limit. This was in categories spanning baby, kitchen, cellphone accessories, health and personal care, beauty and beyond.

After collecting the data we concluded that the 250 character limit, as presented by “experts” and Seller Support alike, is simply a myth. In fact, every category had listings with indexed search terms ranging from as low as 300 characters to as high as 1400. Many were in the 500 to 600 character range, with a few reaching 800+.

A few listings in the kitchen category hovered around 350 indexed characters, while some in health and personal care averaged closer to 600. This may mean that different categories have their own limits, but our test was too small to confirm this.

We also noticed that in many categories the number of words indexed could possibly have a limit. In many categories it looked like keywords in excess of 100 were not being indexed. So there may be a word limit rather than a character limit, but again our test was too small to confirm.

What else did we learn?

Another thing we witnessed was that special characters, such as commas, were often indexed as a piece of the whole search term, connecting words together to form an incomprehensible term. Basically, you should NOT use special characters in your search terms because it appears to create errors in indexing.

Where the data gets really interesting is when we tested whether or not listings appeared in search results for phrases that aren’t found in the search terms (or the listing description for that matter) in the exact same order.

Why would we check for that? Because it tells us whether or not repeating keywords in the backend is necessary (i.e. “garlic press stainless steel garlic press garlic crusher press”). This was a concern because in a few of our scraped results we saw repeated keywords being indexed multiple times. If there IS some sort of limit, and repetition isn’t necessary, we need to know so that we don’t waste valuable real estate.

We concluded that repetition is NOT necessary. As you’ll see, by taking logical long-tail phrases that were NOT found in backend search terms in exactly the same order, and searching for them in conjunction with the ASIN, we found that these listings still rank.

In the next example, we looked at a diaper bag with ASIN B00UV2YLMK. We found the backend search terms were diaper bag backpack mom tote small stylish black baby diaper bags designer purse twins wet canvas boys men personalized large stripe fashionable dads cheap cute trendy organizer leather cotton girls insert discount man canvas washable white.

So we searched for “diaper tote”. Although both words are present in the search terms, they were not listed together in that order.

Here’s the positive result:

Is the rest of the listing indexed?

The last piece of crucial data that we determined from our test was whether it was necessary to copy keywords from the listing itself over into the search terms field. Many people, including Seller Support, have claimed that it is NOT necessary to put keywords found in your search terms in places like your title, bullets or description as well.

This may have once been true, however our research indicated unequivocally that this is no longer the case.

In all cases over 80% of keywords that were indexed were also in the visible listing text. More often this was over 92%, however some listings had very few search terms to work with. Furthermore, over 90% of keywords that were NOT indexed were also NOT found anywhere in the listing.

Let me repeat that – if you want to be indexed for as many characters as possible, make sure the keywords are found in your listing. And this includes product descriptions. That’s right. We saw keywords indexed that were found only in the description areas… the part of the listing everyone else claims is not indexed.

But wait… do search terms matter at all?

We’ve established pretty clearly that keywords in the search term area only index IF they are also somewhere in the visible listing. We’ve also seen keywords indexed that were not in the search terms at all, only the description. This begs another important question: “What IS the purpose of the search terms, if they have one at all?”

To test this, we would need to remove ALL the search terms from some listings. However, the listings couldn’t be throw-away ones for products no one cares about, because we’d need to see how it impacts views. Since it would be hard to find people willing to risk their established rankings, I would have to take one for the team.

So, I completely removed all 4,000+ characters from the search terms fields in my two most popular listings… for science.

All keywords were stripped from the search term area, and the list of keywords added to the product description area instead (these were EBC listings, so no one actually sees the product description). If the listings were still indexed for these keywords, it would show that having them only in the description was sufficient.

To determine whether the search terms had any effect on a listing, each individual keyword plus the product ASIN was entered into the search bar on Amazon. Each one came back with zero results. It was looking like search terms had a purpose after all. This wasn’t what we expected to find, so we looked deeper. When entering a key PHRASE (more than one word), even if it didn’t make any sense at all, it would come back as indexed – as long as it was in the description.

To summarize: keywords in the title and bullets were indexed, both individually and in phrases. However, keywords in the DESCRIPTION on listings with no search terms were NOT indexed individually, but only as multi-keyword phrases. When we tested SINGLE keywords on listings that also had them in their search terms, we found they were indexed.

What does this mean for us sellers?

We need to increase the number of relevant keywords our listings are indexed for to the maximum possible.

Here is the summary, based on our research conducted across multiple categories, listings and selling accounts, on how to properly setup your backend search terms:

  • Use up all space available to enter individual, relevant keywords. Use only a space to separate them, not commas or other special characters.
  • Make sure each keyword in your search terms is also somewhere in your listing title, bullets or description area.
  • While it may help to keep words in a logical order, do not repeat terms in order to keep key phrases intact.

More pro tips for getting indexed


Sometimes keywords are not indexed despite obvious relevance to the listing. On the rare occasions that this happens it could be because your product is in the wrong subcategory.

When you create a listing, you choose the subcategories (or “browse nodes”) yourself. In some instances, you may have chosen the wrong browse node and that is simply an error on your part. However, in many other cases Amazon shifts listings into new subcategories, often without notice. What’s worse is that, unless the listing is ranking within that subcategory, it won’t be shown on the listing itself, making it difficult to determine what has happened.

Make no mistake, being in the wrong subcategory has a huge impact on relevance. To illustrate, if you sell meat claws, but are categorized in pet supplies, no amount of SEO or promotions or ads will cause you to be indexed, let alone rank, for anything related to “meat claws”. If you are experiencing difficulty getting indexed for obviously relevant terms, you may need to contact Amazon to determine which subcategories your product is really cataloged under.

AMS ads

If you are starting to get the hang of properly optimizing your listings and search terms, a great tip to help gain more exposure, sales, and ideally indexing, is by using AMS (vendor) ads.

Why is that? Regular sponsored product ads work off relevance. If the term you are trying to advertise for isn’t considered relevant, the ad won’t get any impressions. However, AMS ads don’t operate that way. You can create an AMS ad for any keyword or any product (even if you don’t actually sell it).

That means, if there are terms you’ve deemed relevant but are having difficulty getting indexed for, you can create AMS sponsored product ad campaigns and target those terms. If they underperform, AMS automatically switches them off. If this happens, simply create a new campaign with those same terms. Ideally you’ll land a sale or two and that action should index your listing for the new key term.

The “more details” section

Fill out your “subject matter” terms, and for that matter, probably all of the “more details” section.

We’ve had several reports that keywords added to the subject matter section are immediately indexed. Further, we’ve speculated for some years now that the purpose of “more details” has always been to help with relevancy. And we can clearly see that relevancy matters more now than ever.

Putting together the pieces

It is our firm belief that the recent change sellers have experienced does not reflect a hard character limit on search terms, but rather a refining of what Amazon considers relevant.

If this is true, it means Amazon no longer needs to rely solely on conversions, which are easily manipulated with promotions, to determine the relevance of a listing for a particular search term. Listings should no longer be shown at all for search terms that aren’t completely relevant.

Search terms DO have an effect on the indexing of listings. Despite the fact that search terms that are not present in a listing will not index, listings with no search terms will NOT index individual keywords from the description area, only phrases.

You can increase indexation, and therefore visibility, by filling out your search term area with individual keywords, and making sure each word is found somewhere in your listing title, bullets or description.

  1. Anthony this is solid. It confirms most of what we have found and reported on with one exception.

    We have found almost exclusively that new listings all fall around the 250 character limit…so I think saying it’s a myth is a bit misleading.

    Older listings are a whole different ballgame and agree it seems unique to a listing/category.

    1. Keith, I totally understand what you are saying.

      I wasn’t trying to be misleading, but the concept if it being a myth involves more than just character count. Its the hysteria that surrounded the “change,” and the fact that so many people were sure that their listings had changed and they were losing impressions and sales because of it. Then, bad advice on how to handle it was coming from both seller central AND experts.

      Regarding your statement, while I did mention in the article that this may not be the case for new listings, I am still skeptical until proof is provided.

      1. I totally agree, Anthony. The first article I saw that came out was really poorly done, which is why I responded with my own after we did a bunch of testing.

        Not sure if you read it, but our findings were pretty similar and our feedback to sellers was pretty similar.

        We’re going to keep testing on this as some of our data on duplication and such is a little different.

      2. I think one of the issues we are running into is that people don’t know how to test properly or interpret the data properly.

        In my humble opinion, the best way to test moving forward…if you have a NEW listing, fill out the front end with ONLY your big key terms but leave it as bare bones as possible with NO search terms in the back end. Then check indexing on those key terms. THEN add less than 250 characters to the back end, all of which are NOT in the listing. Then check to see if they index.

        Then add more than 300 characters to back end and test again. Then flesh out the entire listing as much as possible and check again. This will test for character limits in the back end AND in the listing as a whole.

    2. I think Keith has a point. Experiments that we’ve contacted on our own account last week and on friends accounts that we pushed to do the same tests show inconsistencies.

      Seems like new listings (new being somewhere around March/April) are only ranked for 250 characters (Beauty category). Exceeding 250 with a few characters invalidates all back end search terms, so you will not rank for any of those, except where the word is also in Title, Bullets or Description.
      We’ve noticed some correlation between answered questions content and ranking.
      Older listings and accounts, were RANKED for keywords that appear only on the search terms, and not in the visible listings. Even with 2000+ characters. Those are again, old accounts and listings made prior to 2017. So there’s inconsistency and it may be that Amazon is rolling out a limit or what not.
      One more thing we figured out – if you put completely irrelevant words in the search terms, and limit to 250 characters (in a new listing) it ranks. Why would it do that I have no idea, no one is looking for skin oil in conjunction with “Skittles” or “Salad”… but it does rank (makes you think, doesn’t it?)
      Another thing – it works with your competitor’s name too – but AFAIK it’s not supposed to rank on competitors names.

      1. “if you put completely irrelevant words in the search terms, and limit to 250 characters (in a new listing) it ranks.”

        Umm. This is definitely something I’d like to see more evidence on. Because if that is the case, it completely flies in the face of why the change was made in the first place (to ensure relevancy).

      2. Hi Anthony,

        Here’s what we did, step by step, without revealing too much information about our listings:

        1) Tested 2 new listings and 2 old listings in 1 account that exists since January 2017.
        Then – I tested 2 old listings in an account that opened before 2017, with 2 of their oldest listings.
        2) I’ve separated in all ads words that appear in the ad and in the search terms and words that are not (exclusive for Search Terms).
        3) I manually tested (it took a few hours, yes), a large (too large) sample of words from each group in several accounts.

        So far the discrepancy was great – old accounts showed ranking for more than 2000 characters, while new accounts showed no rank (I checked all words that do not appear in Title Bullets Description).

        So I left the old accounts alone for now, then performed the following on the 2 new listings in the newer account:

        1) Backed up all search terms
        2) Deleted all search terms
        3) Saved
        4) Went into edit again, and added only 20 keywords (came to be close to 200 characters with the spaces, no comas or special characters).
        5) The 20 keywords that I’ve re-added were split into groups: Competitors brand names, Irrelevant keywords and relevant keywords.
        6) Saved than waited about 15 minutes
        7) Rechecked in both listings, manually and all keywords in search terms rank, including Skittles (for oil, I mean give me a break), Trump and Salad. The competitors ranked as well. (now let’s discuss this as an ethical issue?)

        It’s interesting, because if under the new algorithm Amazon ranks back end keywords (all of them) if you limit to 250 characters – you can actually choose what will rank and what will not rank.

        3 notes, if you read thus far, it may be interesting:
        1) Specific keywords that didn’t rank when there was more than 250 characters in the new account, now ranked when it was under 250. (That would support the claim that over 250 keywords invalidates the entire back end search terms… – again I’m not claiming it is, but surely in some cases it does, possibly new accounts.
        2) This should be repeated over time probably. It may be that when making changes in the Search Terms Amazon does give you a ranking, and after a while, after the algorithm recognizes that Skittles and Oil have no correlation and nothing to do with each other – maybe it will stop being ranked… We’ve only conducted this experiment last week, not enough time has passed.
        3) Different categories – We have only tested Beauty. Have no idea (and also less interest at the moment) in how other categories behave… Got to keep a focus, right?

        I have to say one more thing – your article, is BY FAR the most comprehensive that I’ve seen about this specific topic, specifically relating to all the buzz lately around the limitation (or lack of) of back end search terms.
        I’ll be happy to pick up more gems in the future, I see you’re working on a book and that could be interesting and I encourage all Amazon sellers out there, small or big to take action and expand their knowledge in every occasion they have.

      3. Wow. That is some great info. Thank you.
        This completely turns a theory I’ve been working on onto its head, but it is good information.
        I’ll add another dimension to my tests when I launch my new products in the next month. I would really like to see if we continue to have control over indexing and ranking for irrelevant (or otherwise whatever we choose) terms.

  2. So, if keyword entered in Search term section indexed only if it exist also in visible part of listing, it looks like search terms have no any sence to fill out.

    1. It almost seems that way, but the jury is still out as to whether or not this is the case with NEW listings.
      If you have an old listing, just reduce your back end search terms to single keywords found within the listing text. That way, at least they will index individually as well as in phrase format.
      If you have a NEW listing, you should test to see if back end search terms that are NOT found in the listing itself index. If this is the case, you get more room for keywords you don’t have to weave into the text of your listing. However, so far no one has provided proof of this, so you won’t know unless you test.

  3. the 250 character limit is active at least on and on

    FR: If you want to list a product in FR and you have more than 250 characters you get an error and the product is only listed if you go under 250.

    DE: As soon as you have more than 250, no keyword is indexed anymore. We had that problem with more than 100 ASINs. After removing keywords and go under 250 characters, the listings were findable after a few minutes.

    Category was Kitchen & Baby

    1. Thank you for sharing this information. I encourage anyone who is uploading NEW listings to test and find out how your individual category on your marketplace is reacting.

  4. Great and solid article Anthony. Thank you.

    I think all people working as Amazon SEO should be grateful.
    On our side, we tested a lot, with a similar “scientific approach”, and can confirm a progressive reduction of “accepted” search terms, most probably due to the fact that A9 is evolving towards more complexity. Therefore AMZ prefers to index higher and higher a relatively lower number of sellers i.e. the once that are able to discover and spread on their listing the extremely high relevant KW and search terms only. After all, they like much more to manage only 1 seller that develops 100,000 USD/YEAR of turnover (as he knows how to optimize) rather than 25 sellers that, all together develop the same amount of sales..

  5. Thank you so much for this detailed article. You have confirmed everything Lisa Suttora has tested and taught in her group, and whilst I trust her knowledge you are the only other person I have read about that has had the same observations. I like how you presented it. It was very informative and easy to understand. Thanks.

  6. There’s one important piece you’re missing here. There seems to be a cut-off date somewhere between March-May where Amazon made a change. Keywords added BEFORE that date are continuing to index. Keywords added AFTER that date are not, beyond the 250-character limit. We tested and verified this for a large number of products.

    1. “We’ve established pretty clearly that keywords in the search term area only index IF they are also somewhere in the visible listing.”

      This is also inaccurate. I’ve tested with gibberish character strings only in search terms, not in the listing ,and had our listing show up.

      1. I am not saying you are wrong, but this was our finding across multiple categories, as was illustrated.

        If you have contrary evidence, please, by all means present it.

      2. I can’t share client data, but we added multiple keywords to the effect of ‘thisistestkeywordnumberone’ to ONLY back end search terms and had listings show up for those searches within 60 minutes.

    2. I think the article mentioned that we haven’t been able to test this on NEW listings. Another issue I see people running into is not properly testing in each category.
      As in, people are making bold claims that bullets are no longer indexed, largely because of the wonkiness where Amazon chooses to index only phrases and not individual words, then they test for individual words.
      The best way to test this is by creating a listing from scratch and testing at every level.
      And, the other important thing to note here is, if new listings do have a hard limit, yet all keywords in the listing still index, what benefit is there to having back end keywords at all?

  7. This is a super juicy topic. This is part of the reason many of us on this thread as consultants and service providers have busy businesses…this stuff is difficult.

    Thanks for everyone continuing to contribute to this thread.

    Amazon is a wonderful, ever-changing platform that as Bezos says, “is always in Beta.” It’s never stagnant and we can’t be as well.

    I’m always reminded that just because we see something one way…it doesn’t mean there aren’t many other profitable, sound ways to get the same result.

  8. Here’s the feedback from our SVS rep – August 2, 2017

    Following up, below are the recommendations on generic keywords as discussed.

    * There is a new length limit of 249 characters, including spaces, for Generic Keywords.
    * If an ASIN’s generic keywords exceed this limit, none of the generic keywords are indexed.
    * Generic keywords can have all lower case letters. There is not restriction on this.
    * There is no need for punctuation e.g. ; : ,
    * Words do not need to be repeated in the Generic Keywords field. Once is enough.
    * No need to repeat words that are mentioned in other indexed fields, such as title and description.
    * It is sufficient to include either singular or plural of words. It is advised to use whichever is searched for the most. For example, “headphones” is searched for more than “headphone”. We advise a “test and see” approach as to whether to include singulars and plurals of words or not.
    * No need to include the ASIN’s own brand name in its Gen KWs.
    * It is not allowed to include other brand names or ASINs in Generic Keywords.
    * No need to include adverbs (nearly, really), pronouns (I, she, him), prepositions (after, in, to, on), conjunctions (and, but, for, if, or), determiners (a, an, the), superlatives (best, cheapest, rarest).

    Search indexes Generic Keywords to a larger extent than Subject Keywords. For subject keywords, the character limit is 2000 characters and includes delimiters. For subject keywords, same guidelines as above.

  9. Amazon posted now something about that in Sellercentral UK, so it is official:

    Amazon launched a feature that limits the length of the generic keywords attribute to less than 200 bytes in the IN marketplace, 500 bytes in JP and 250 bytes in every other marketplace except CN. The limits have been shown to improve the quality of search results. It applies to newly registered and existing ASINs.

    Key Guidelines:

    Keep content within the prescribed length limit (less than 250, 200 for IN, 500 for JP):
    Length limit applies to total content in all generic keyword fields (a max. of 5 attributes).
    Whole entry will be rejected upon exceeding limit.
    Number of bytes equals number of characters for alphanumeric characters (e.g. a-z, 0-9) while other characters can be 2 bytes or more. Examples include ä (2 bytes), £ (2 bytes), € (3 bytes) or ❤ (3 bytes).
    Spaces and punctuation (“;” “,”, “.”) do not contribute to the length limit, but words should be space-separated. Punctuation between words is unnecessary.
    Optimising keyword content for search discoverability:
    Do not include keywords that are not descriptive of the product.
    Do not include brand names (even your own) or other product identifiers.
    Do not duplicate content present in other attributes, such as title and bullet points.
    No need to repeat keywords; once is enough.
    Use keywords that are synonyms, hypernyms or spelling variations of content in visible attributes (e.g. if product title is ‘whiskey’, use ‘whisky’ in generic keywords).

  10. Hi I am a bit new in all of this and had a few questions hopefully one of you can help me. If I understand correctly in the 250 character limit I should not include any of the words that are already in the title or the description as it already gets indexed for?
    2 When indexing for specific words, have you done any tests as to wether words in plural encompass word in singular? For example putting photos would mean I dont need to write photo as those characters are already included in the name?

  11. FYI – we just tested and found that words that are in the search terms and that are NOT in the visible listing DO index.

  12. Great article!!

    In my very simple tests, I’m finding that the description is not indexing at all. The title is indexed, but it only works if the search query doesn’t contain extra keywords that are not in the title. Case in point:

    Island of Fog Box Set: Books 1-3 of the Magical Fantasy Adventure Series

    This is my exact title. Now try this:

    Island of Fog Box Set: Books 1-3 of the Magical Fantasy Adventure Series Blah

    The word “blah” on the end causes this to fail. Amazon suggests my title underneath, but obviously with real search queries there would be plenty of other results, so my book would never be suggested.

    Re-ordering the keywords doesn’t matter. Nor does omitting some of the keywords. But adding one is BAD.

    Now, here’s something quirky. I searched for an exact phrase in my description (“positive feedback from readers”) expecting this would pull up my book.

    It didn’t.

    However, another book came up. The phrase I’d searched for is actually (probably mistakenly) included in the contributor field at the top. Click the “& 2 more” bit to the right of the contributor on this page:

    So obviously those fields are indexed. But it looks to me like the description is definitely not.

    When I do the ASIN + background keyword search, it works great IF you use only your keywords. Any extras, and it fails. Eg:

    Keyword field is “mythical legendary monsters creatures”

    Search for:
    B00OEDINJY monsters mythical (good)
    B00OEDINJY monsters (good)
    B00OEDINJY monsters mythical creature (good)
    B00OEDINJY monsters blah (no result)
    B00OEDINJY blah (no result)

    Note also that using “creature” or “creatures” is good, but “creat” is a fail.

    Hope this helps!

  13. In fact…

    To add to my previous note, you can mix keywords from OTHER keyword fields and the ASIN + keyword search works just fine. So:

    Keyword fields:
    “mythical legendary monsters creatures”
    “preteen children kids”

    Any combination works:

    B00OEDINJY monsters mythical kids (good)
    B00OEDINJY monsters preteen (good)

    This tells me that we can stuff our fields full of keywords in any order, and the search will find them all quite nicely. It will also find an included keyword that’s NOT in the keyword field but IS in the title field, in this case “fantasy.” But again, if you add a keyword you don’t have, the whole thing fails.

    B00OEDINJY monsters fantasy (good)
    B00OEDINJY monsters fantasy blah (fail)

    And if you include a word from your description that’s not in the title or keyword field, that fails too:

    B00OEDINJY monsters fantasy positive (fail)

    This article has helped me a lot, but the biggest tip for me was using the ASIN + keyword for very quick in-depth testing.


  14. Thanks alot this has helped. Before, my listings would index words that were only in the search keywords. Now, after August 1, with my new listings, This wasn’t the case. After reading your article, I included some of the main search keywords in my bullet points. Now, the keywords that are in my bullet points are showing up. So I guess from now on, I have to fill up my bullet points with as many keywords as possible. Also, do you know what the character limit is on bullet points?
