What Factors Make a Good Keyword Research Tool?

Keyword research tools are undoubtedly a boon for website optimization, but you must consider a few factors before deciding to get one. Here is the list of factors that you should consider.

Keyword research with language target

If your business or site targets audiences of specific regions, keyword research for targeted languages should be your priority, primarily because it will be on top of your multilingual SEO. 

Check if your chosen tool has a multilingual glossary and termbase to support your strategic approach. It is necessary to prepare your content with relevant keywords in the target languages before sending it to a language service provider (LSP) for translation or localization. Then your content will successfully attract and retain customers on a global scale.

Statistics for word competition

It is imperative to evaluate the difficulty of a new keyword vertical before targeting it. Your keyword tool must have the ability to analyze keyword competition that would tell the difficulty level to rank for a particular keyword. 

The statistics will help you judge keyword competitiveness and estimate the time and effort it may take to achieve top rankings for the targeted word. 

In-depth SERP overview

For every keyword, search results differ widely based on the location from where the user is searching. Therefore, your tool must analyze SERPs from different countries, especially the countries you want to target. 

The in-depth SERP overview should also show you real-time search results from any location, give you accurate ranking difficulty score and elaborated SEO stats, analyze organic search results, SERP position history, etc.


Checking your site ranking regularly for the chosen keywords is not enough to know if your effort to optimize the site is working. You need to have a detailed report that will include an analysis of the pages towards which those target keywords drive traffic. 

Besides, it should contain the facts such as traffic your target keywords drive to your web pages and the list of keywords driving the most traffic to your site.  


Keyword research tools will generate an extensive list of keywords, sometimes hundreds of thousands of keywords. Finding the most appropriate keyword, in such a case, is almost like searching for a needle in a haystack. 

But with the help of a proper filtering option, you will be able to narrow your search significantly. Look for the keyword filter option in your tool of choice. This feature will help you filter away those keywords that don’t conform to your requirements.
