Comprehensive keyword research is just as important for Amazon SEO optimization as it is for classic search engine optimization. While Google offers an in-house tool for the determination of search volumes with the AdWords keyword planner, Amazon is still missing such means.
Research with the AdWords keyword planner
Fortunately, you can also use the Google tool for researching keywords for the e-commerce platform. You simply have to pay attention to the previously mentioned difference in user search behavior in order to obtain significant results in the end.
From the results of the research with the keyword planner, you have to determine which keywords play a role for Google but are ultimately irrelevant to Amazon ranking optimization. This is especially true for transactional and informational keywords, as the following example illustrates:
If you ask the keyword planner to display relevant keywords for the search term “printer”, the tool will present you with the following search results (among others) that enjoy high search volumes:
- “best printer”
- “printers for sale”
- “printer comparison”
- “printer test”
- “refilling printer cartridges”
- “printer problem”
A user on the Amazon search machine wouldn’t use any of the search terms listed above. Since they’re already on a sales platform, they know that they don’t need to explicitly state their intent to purchase something. They also wouldn’t be turning to the Amazon search for tips on problems with a specific printer. So for Amazon SEO, these phrases are irrelevant, even if they have a high search volume on other search machines.
Research with Amazon keyword tools
The ever-increasing significance of Amazon for e-commerce is obviously not lost on providers of SEO tools. Now there are individual services that are specifically targeted on Amazon searches. The company MerchantWords, for example, built a database with over 170 million international keywords (in English, German, Italian, Spanish, and French, among others) that you can use for your Amazon keyword research for a monthly fee. In addition to an estimated value for monthly search volume, the tool also identifies the product categories in which many keyword suggestions frequently appear.
Also interesting is the tool Sonar, which can be used for free as part of the online analysis platform Marketplace Analytics. The web application shows you the search volume of the desired keyword as well as various alternative suggestions. It uses a rating scale to do this, where the value 1 means a very low, and volume 5 is a very high search volume. The underlying database is regularly updated and already has over 110 million English keywords, according to the provider.
Research via Amazon auto-complete
The Amazon search machine, like Google, has an auto-complete feature. While the user is entering a search query, the feature automatically provides suggestions for the auto-completion of the searched term. It also provides related keywords and presents the most important product categories for each keyword entered.
Random sample entries don’t only help you identify valuable keywords for your SEO strategy. They also are the quickest way to test the suitability of certain keywords on your temporary list. This way, you can reduce the risk of using a keyword with a high search volume that’s actually entered by users for something entirely different than your product.
Structuring and hierarchy of your Amazon keywords
A good keyword set isn’t simply characterized by containing relevant search terms. During the research process, you should also attempt to make the list as clear and user-friendly as possible. You might find it difficult to reach the full potential of your research results, especially with complex Amazon SEO campaigns that contain lots of keywords and keyword combinations. A common practice is to arrange related keywords in clusters. The aim is to divide your set into multiple groups, such as “general”, “longtail”, “seasonal”, or “competition” and therefore simplify the overview.
The last step before preparing your product pages is to set your researched search terms into a hierarchy. Use the search volume values displayed by the tools mentioned above, taking into account the information obtained by the product and competition analysis, to create the most promising and successful ranking order possible.
