7 Best Free & Premium Keyword Research Tools for SEO

A keyword research tool is very useful for any business or individual because of its powerful marketing capabilities. It is getting much harder to rank on search engines due to the increased level of competition for desirable keywords as well as changes in search engine algorithms. As a blogger myself, I have researched many keyword tools and have narrowed it down to 7 best free and premium keyword research tools that I believe every blog owner should personally try. Luckily, most of the premium keyword research tools have free trials or money back guarantees so that it won’t cost you to find the best one for your website.

#1 SEMrush

SEMrush provides all the great features that you expect for a premium keyword research tool. SEMrush not only boosts the performance of your day-to-day tasks, but also provides an in-depth analysis that is very clear and easily incorporated into your digital marketing procedure. As a result, your business significantly improves its productivity by more efficiently completing marketing tasks. For more information, check out our extensive review of SEMrush here.

#2 KWFinder

With KWFinder you can find keywords that you can easily rank for your website or business.

Long Tail Pro is the best at discovering less competitive keywords that can get you high-converting online traffic.
