ASIN Search Term Report

Why Are ASINs Displayed In Amazon Sponsored Products Search Terms Reports?

One of the most frequently asked questions we get about Amazon Sponsored Products is, “Why are there ASINs in my Amazon Sponsored Products search terms reports?” This question arises whenever we explain how Automatic Targeted campaigns work and show excerpts from a search terms report. We’ve spent a good deal of time experimenting with Sponsored Products and have been able to come up with an answer.

Why You Find ASINs in Search Terms Reports

In the image below, you can see four ASINs that appear as a Customer Search Term from this Automatic Targeted campaign. The highlighted fields are the ASINs of other products where this ad was shown.


But why do ASINs appear instead of keywords? In order to understand how this happens, let’s dig a bit more into how Amazon constructs a search term report.

How Amazon Constructs a Search Term Report

If a buyer goes to and they search for “apple slicer,” you’ll notice that Sponsored Products ads are displayed at the top, bottom and right-hand side of the page. Every time Amazon shows one of those ads, it gets counted as an impression for the search term entered.  If a user clicks on one of them, it then gets counted as a click.


Go a step further and click on one of those ads and examine the URL of the next page. You’ll see a URL like the ones below. Note the bolded keyword “apple+slicer” in the URL:

(From an ad at the top)

(From an ad on the right side)

On the product detail page, you’ll notice a couple of things. First, the search term “apple slicer” is already entered into the search box. This means the product detail page you just searched for remembers you. Also, notice on the same product detail page, that more Sponsored Products ads are being displayed. Since Amazon knows the search terms the visitor used to find that product detail page, the ads displayed on the page are also attributed to the “apple slicer” keyword. Meaning, if your ad was shown here, the impression and click would get assigned to the “apple slicer” search term.

That explains how the real user search terms get populated but it doesn’t explain yet why the ASINs show up in the search terms report. For this part, you need to consider statistics from SimilarWeb. The stats show that more than half of the traffic comes from referral links, organic search, social shares, email and other sources.

One source could be a detail page like this:

Note that those links usually don’t contain keywords. Whenever traffic comes from one of those external sources to a product detail page—and does not originate from a search on—Amazon will still show Sponsored Products ads on the page. But without a search term to reference, the Sponsored Products system needs to tie that impression to something else. In these cases the search term displayed in the report is the ASIN on the product detail page that was shown.

Moving Forward

Armed with this knowledge, you can start to make some inferences about your competitors’ traffic sources. If your product is getting a lot of impressions and clicks from a competing ASIN, this is probably a good indication that their product receives a lot of traffic from external links.  One popular Sponsored Products strategy is to take the ASINs found in the Search Terms report and search for them on Amazon to see if the ASIN is an actual product. From there, you could use our keyword research tool, Scope, to see what keywords the ASIN ranks for. This can give you terms you may not be currently using.

Those sources might include things like:

  • Organic (Google, Bing, etc) search results
  • Amazon Associate (affiliates) websites
  • Social media including 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

  1. Thanks! I was just noticing this on my report from an auto campaign. Not sure how this can benefit me, but at least I know why it’s happening now.

    1. Hi Leif, I think that’s not a good strategy. I mean, it won’t take anything from your ads budget, unless someone is all of a sudden searching for products using ASIN’s. Highly nulikely, I think. If you have access to AMS, you can use those ASIN’s from the search term reports to create display ads. This way you will gain more visibility which will mean more traffic from that “ASIN keyword” which you already identified as a good keyword for you.

      Hope this helps!

  2. I just checked this out for some of my search terms. I found that when I click on an ad that’s displayed on a product detail page it does NOT retain the original search term in the url. So, the origin of the search doesn’t have to be an external source for the ASIN to show up as the Search Term. It can also begin as an Amazon search, but the ad that’s clicked is on the detail page for the product with that ASIN.
    Your advice on how to take advantage of it is still the right strategy. It’s a fantastic way to get new, good converting, search terms!
