ASINs in Search Term Reports: Answers to Your Questions and Optimization Suggestions

One topic we’re often asked about is about ASINs appearing in the Search Term report within Amazon’s Seller Central and the Ignite application. In this Q&A post, I’ll set the record straight on what’s up with these seemingly odd so-called search terms and I’ll explain how you can use them to your advantage.

Q: The Search Term report is supposed to show the words that shoppers input into the Amazon search field when trying to find a product. Shoppers don’t search by ASIN, so why are there ASINs in my Search Term report?

A: ASINs in your report are the result of one of your Sponsored Products ads appearing on some other product’s detail page and the shopper clicking on your ad there. The ad that was shown and clicked is from an auto-target campaign where Amazon has provided the keywords.

Q: Why some ASINs instead of search terms? More specifically, why an ASIN and not the search terms that the user entered to get to the first ASIN’s detail page before he or she clicked my ad?

A: Not all product detail pages (and, by extension, the other products are shown on them) are derived from internal user search inputs. A lot of traffic comes from external links, including:

  • Organic search results generated by sites that index Amazon listings (Google, Bing, etc.)
  • Amazon Associate websites and links (affiliates)
  • Social media links such as those from Facebook, YouTube, Twitter, and others
  • Content from any other websites such as price comparisons, product reviews, etc.
  • Other non-search related pages on Amazon
  • Amazon’s various emails to buyers

These external sources don’t come from Amazon search terms but Amazon has to associate them with something, hence the ASIN.

Q: Okay, but can I just delete these ASINs from my downloaded Search Term report then? It’s a pretty big spreadsheet already.

A: I know that Seller Central reports can be cumbersome. If you want to get your report a little more under control, sort by the Search Term field so you can isolate the ASINs (they are almost always the alphanumeric entries starting with “b”). Cut these out and add them to a new spreadsheet called “ASINs to Research.”

Q: Okay so now I have a new list of ASINs for products that aren’t mine? What gives?

A: These ASINs indicate that your product was shown on the other product’s detail page because Amazon is, for some reason, connecting your product with the product attached to the other ASIN. Something between your listing information and that of the other ASIN is telling the Amazon algorithm that the shopper who searched for one might be interested in the other.

Here’s an example: Say you sell dog sweaters (love dogs, not judging). A shopper Googles “dog sweaters buy argyle.”

The user clicks that top listing and is taken to (notice that there are no keywords in the URL, just the title and the ASIN getting passed to Amazon). Once the user gets on the page, he or she sees tons of other cute dog sweaters and clicks on one of those listings (let’s say, which happens to be your Sponsored Products ad listing).

What got the user to your page isn’t an Amazon search with user search terms matching your keywords. What got the user there was another product’s listing derived from a search engine followed by the user clicking that result and landing on a product detail page followed then by the user clicking on your Sponsored Products ad that Amazon was showing on that page. And that is why the ASIN for the first product is considered the referrer or “search term.”

Q: I get that the referral has to be assigned to some kind of linking and tracking, but what’s really going on? What’s connecting my product to that other ASIN?

A: There is something in your listing and that other ASIN’s listing that Amazon has linked, some connection that the algorithm has made between keywords. This can be a good thing or a bad thing, but now that you understand why it’s happening, you have the power to leverage it as an advantage. Here’s how: Check the other ASIN and see what’s going on and if the connection between your product and that other ASIN makes sense.


In the example above, both products are argyle-pattern dog sweaters so it makes sense that they would be shown together given that the keywords in each listing probably overlap quite a bit. It is reasonable for the Amazon algorithm (and for human users) to associate these products) as these are competing products.You now have a gift in having a closely-linked competitor’s ASIN and you can do a reverse-ASIN search on it using a tool like Scope and pick up any keywords that you want to incorporate into your listing so that your product gets the original organic match (the click is free) instead of being a suggested Sponsored Products ad (the click costs you). You should also read the competitor’s listing and pick up any pain points and address those in your own listings. Here is where you can turn your competitor’s Q&A and reviews into your own positives.


Let’s throw something else into the mix. What if another ASIN in your report corresponds not to another argyle dog sweater but to an “Extra Large, Premium Silicone Food Safe Cat or Dog Feeding Mat” and your SPA is showing on that detail page? Is that a good match that will lead to conversions? Not likely. It will certainly lead to impressions, it may lead to a few clicks, but it’s not likely to lead to conversions. So what should you do now? Again, hit that reverse-ASIN tool and Scope out the other ASIN’s keywords relative to your product’s keywords. Maybe you both have “dry dog” set as a match type. It would make sense that both products would tout dryness as a feature. But now you know that you should probably change the way you’ve used “dry dog” as a keyword or you could even lower the bid or make it negative if it’s bringing you the wrong kind of traffic.

Q: Okay, if these ASINs that belong to my competitors are so valuable, should I add the ones that seem closely related to my own manual-target campaigns and bid on them?

A: You cannot add them as manual-target keywords. They are in auto-target campaigns only and what Amazon sweeps up in those searches. By the same token, you cannot set ASINs as negative keywords. However, you can use Scope to research those ASINs and make the keywords that you find there into manual-target bids or negatives. And you should do just that.

Key Takeaways

  • Don’t toss the ASINs in your Search Terms report! You can work these ASINs to optimize your own listings by picking up competitor’s keywords and making negative any keywords that are costing you because they are bad matches.
  • Use both art and science to optimize your listings based on this newly discovered ASIN gold:
  • The Art: Look at those listings for the other ASINs. Notice bullet points, images, reviews, Q&A, etc. Pick up pain points in competitor’s listings and incorporate them into assets in your own listing. Example: Competitor’s listing has a few reviews saying that the dog sweater shrinks to mouse-sweater size after one wash. Revise your listing and add a bullet stating the washing instructions and that you offer a guarantee should the user buyer be unsatisfied. Or if you see that a competitor has lots of high-quality pictures of happy pups wearing their sweaters, consider investing in professional photos for your listing. With some practice reading competitor listings, you’ll get a good feel or what shoppers want to see in a listing and optimize yours accordingly.
  • The Science: Use Scope to dig deep into the keywords of your competitors and adjust the keywords in your listing (keeping in mind that title carries the most weight followed by bullets). This will help to optimize the organic ranking aspect of your listing. But don’t stop there. Work your Sponsored Products ads manual-target campaigns based on what you’ve picked up. Add strong keywords, pull back on low performers, move keywords from match-type groups. Throw duds into negatives. Amp all of this up by putting a campaign into Ignite and taking Ignite’s suggestions.
