Build Amazon Keyword Research Tool with API

How to Build an Amazon Keyword Research Tool with API

Amazon is easily the largest e-commerce platform. According to various estimates, its catalog contains from 75 million to over 350 million products.

Navigating through so many items wouldn’t be possible without a search engine.

Luckily, Amazon has one.

Just like any search engine on the web, it plays by the rules of SEO.

That means sellers can implement certain SEO strategies to make their product listings rank better in search results. And the first optimization step will invariably be keyword research.

Before creating a product page, an experienced merchant first finds and collects keywords relevant to their product. That enables them to target these keywords in the listing and improve its visibility in Amazon SERPs.

To find keyword ideas in the most efficient way, merchants leverage Amazon keyword tools that simplify the research process.

With the new Amazon endpoints in DataForSEO Labs API, you can develop such a tool yourself and help sellers who require accurate keyword data from Amazon.

Below we show how to do it.

Building a keyword research solution for Amazon with API

Every keyword research starts with defining seed keywords.

A seed keyword is basically a short-tail term relevant to a business. It’s intuitive and simple, so one can brainstorm it quickly.

For example, if a merchant sells toys for kids, their seed keywords will be “kid toys”, “toys for kids”, “toys for children”, and so on.

Such keywords always have high search volumes and are hard to rank for. Therefore, it’s a good idea to expand a keyword list and find less competitive terms.

That’s what Amazon keyword research tools are needed for.

The majority of them work the following way:

1 The seller specifies their seed keyword.

2 The tool analyzes it and provides relevant keyword ideas.

3 Along with keywords, it offers valuable keyword data so that the seller can estimate the potential of using each returned keyword idea.

Let’s take a look at one of such tools — Ahrefs Amazon Keyword tool.

The tool allows us to specify a seed keyword along with a target location and find keyword ideas for it.

We typed the keyword “kid toys” and received over 800 relevant terms.

While the tool is undoubtedly useful, it still can be improved: Ahrefs could add filtering options to enable Amazon merchants to get more specific results.

With the Amazon endpoints in DataForSEO Labs API, you can build an even more advanced solution.

Currently, we offer two endpoints for developing a keyword research tool: Related Keywords and Ranked Keywords.

Finding thousands of related keywords

Like Google, Amazon has the Related Searches section. It displays keywords related to a search query. The section usually appears at the bottom of Amazon SERP.

Here are related searches for the “kid toys” keyword.

However, Amazon only provided six keyword ideas, which is obviously not enough for comprehensive keyword research.

With the Related Keywords endpoint, you can extract as many as 1554 keyword ideas from this section.

The endpoint uses the depth-first search algorithm for queries appearing in the “Related searches.” The higher the depth, the more keywords you can receive in the response. You can set its level from 1 to 4:

  • 1 – 6 keywords maximum;
  • 2 – 42 keywords maximum;
  • 3 – 258 keywords maximum;
  • 4 – 1554 keywords maximum.

To make a request to the Related Keywords endpoint, simply specify a seed keyword, along with the depth, language, and location parameters.

Example of the POST request:

[
    {
        "keyword": "kid toys",
        "location_code": 2840,
        "language_code": "en",
        "depth": 1
    }
]

Along with keyword ideas, the API response will provide search volume data for each returned keyword. That way, a merchant will be able to roughly estimate each keyword’s traffic and ranking potential.

Example of the API response:

Borrowing competitor ranking keywords

Another way to expand a keyword list is by borrowing competitor ranking keywords. Once a merchant has defined their seed keywords, they can search for their rivals and find out what keywords they’re targeting. The Ranked Keywords endpoint of DataForSEO Labs API can help with the latter.

The endpoint provides a list of ranking keywords for a specific ASIN.

ASIN (Amazon Standard Identification Number) is a unique product identifier that applies to most Amazon products except for printed books. It can be found in a product’s URL and description.

amazon-asin

To discover the ranking keywords of a product, a seller should specify its ASIN along with the language and location parameters.

Example of the request:

[
    {
        "asin": "B00WTDXSDM",
        "language_name": "English",

Obviously, some of the provided keyword ideas might be irrelevant or too hard to rank for due to high search volumes. To help you get more specific results, we added various filtering options.

For example, you can get keyword ideas that have search volumes of less than 500. To do that, apply the following filter.

"filters": ["keyword_data.keyword_info.search_volume", "<", "500"]

If some of the returned keywords are irrelevant to a product, you can narrow down your results and receive only terms for which the product takes from 1 to 5 positions.

"filters": ["ranked_serp_element.serp_item.rank_absolute", "in", [1, 2, 3, 4, 5]]

Moreover, we allow specifying up to 8 filters in one POST request, which can help you get very specific in keyword research. Following the example above, let’s receive keywords with search volumes of less than 500 and for which the product ranks within 1 to 5 positions. To apply two filters at once, we should separate them with the and logical operator.

Example of the POST request:

[

        "asin": "B00WTDXSDM",
        "language_name": "English",
        "location_code": 2840,

                "500"
            ],
            "and",
            [
                "ranked_serp_element.serp_item.rank_absolute",

You can review the filters available for the Ranked Keywords endpoint on this documentation page.

By adding these filtering options to your Amazon keyword research tool, you will gain a significant competitive advantage as the majority of Amazon tools don’t support any filters.

Conclusion

Now that you know how to build an Amazon keyword research tool with API, you’re probably asking yourself:

If I developed such a tool, would it pay off?

Well, we can’t guarantee you anything, but we’re inclined to believe that your tool will be in demand.

We have two reasons to think so:

1 Amazon has 1.5 million active sellers worldwide, and 1,495 new sellers join the marketplace every day. Obviously, some of these sellers will be looking for keyword research tools to make their optimization routine easier.

2 The query “amazon keyword tool” has a relatively high search volume. For example, only in January 2022 it was searched 720 times. That means if you manage to rank well for this keyword, you can count on a steady stream of traffic.

So why are you still thinking?
