SellerSonarNowadays, the majority of online shoppers look for a product to buy via search. That’s how the potential customers of any Amazon merchant find what they purchase. In fact, more than 56% of consumers who’d like to buy products from a single store, search for them on Amazon.

In order to find an item to buy, your customer enters a search term in a search bar. If you want to sell as many products as possible, which you do, your listing should contain keywords that are as relevant to your customer’s search query as possible. This is because Amazon’s search engine selects the product that matches customers’ search and ranks the results in the order of relevancy.

The higher your product ranks in the search results, the more orders you will get.

Said that you’d think it’s a good idea to put a lot of keywords on your listing to increase relevancy. However, you can add only a limited number of keywords to your heading and product description to keep them readable.

Therefore, Amazon introduced backend keywords. These search terms appear in the “invisible” part of your listing. Nevertheless, they are indexed by Amazon’s A10 algorithm and improve your Amazon search terms optimization.

Read further to know how to find backend keywords on Amazon and how Amazon backend keywords can help in your listing optimization to grow sales.

What Are Amazon Backend Keywords?

Backend keywords are one of the two types of search terms on Amazon. These are frontend and backend keywords.
Frontend, or primary keywords, are search terms visible to the buyers. They are located in the product listing heading, bullet points, and description.

Backend or secondary search terms are invisible to shoppers. Amazon hides them in the “Search Terms” section under the “Keywords” tab.

Notwithstanding the “secondary” title, backend keywords play a very important role in your listing optimization. Amazon’s A10 algorithm indexes them alongside primary keywords. Backend keywords on Amazon strengthen product visibility by being invisible themselves.

Backend keywords make it possible for you to squeeze in search terms that you could not put on the visible part of your listing. These can be synonyms, spelling variations, abbreviations, and more.

Here’s a backend Amazon keywords example: if you sell a multicooker, customers may also look for an instant pot or steam cooker. These are backend keywords.
