How to Find the Right Keyword Research Tool

Keyword research is the bread and butter of most SEO professionals, but knowing where to start when it comes to keyword tools can be difficult. If you’re just dipping your toes into the keyword research pool, start with a free service that offers basic functionality. Familiarize yourself with how the tool works and what insights it offers, and try incorporating some of the keywords you find into your website to see if the service has promise.

As you pick a keyword tool, you’ll need to take several things into consideration. Be sure to weigh

  • the size of the keyword database the service offers (SEMrush and Ahrefs are considered among the best here),
  • the features the service offers and whether they meet or exceed your needs,
  • the usability and design interface of the tool, and
  • whether the tool is specialized (like Long Tail Pro) or offers more general keyword information (like Google Keyword Planner).

If you think you need a paid tool but are hesitant to commit, choose a service that offers a free trial. If you’re interested in a service that doesn’t offer a trial, consider signing up for a one-month subscription, and run a test project to see how easily you can incorporate service data into your content and SEO strategies. Of course, you can also reach out to friends and colleagues in your field who use keyword tools, and ask them for a rundown of their favorite keyword accessories.

Remember that it can take time to find the right keyword tool for your needs. Don’t give up if you don’t like the first service you try. With a little experimentation, you’ll be able to find a research tool that fits your needs, experience and marketing goals.
