The 29 Best Free Keywords Research Tools To Supercharge Your SEO

Looking for the best free keyword research tools? Well, look no further!

Keyword research continues to be the most important first step in any SEO effort.

SEO is optimizing your web pages for better ranking in search results pages (SERPs). Part of the SEO process is using keywords: words and phrases that describe what your content is about.

The reason keywords are important for increasing organic traffic is because searchers only find content if Google thinks it’s relevant to what they’re searching for. Google uses keywords as an important SEO ranking factor. That means that the best way to help search engines understand that your content is relevant is to include, in a natural way, the same exact terms that people are typing into Google to find you.

Keyword research also helps you come up with your content strategy by creating content around the terms that you know your audience is looking for.

With over 500 Million "brand new" search terms being searched every day, it's important to have a keyword tool that can offer accurate traffic, competition, and domain insights into billions of keywords.

Although you can pay for access to a variety of high level keyword suggestion tools, this isn’t something you have to do. Instead, you can rely on a combination of free tools to compile a quality list that’ll bring you results.
