9 Free Keyword Research Tools (That CRUSH Google Keyword Planner)

Found this article on The Ahrefs Blog while I was looking for alternatives to the paid SEO tools I had access to on my previous team.

It's basically a short-list of #SEO optimization tools for #copywriters without a corporate budget. Some of them are kooky (hello Keyword Sh*tter) but together, they weave a decent net.

Any other tech copywriters out there? Which tools do you use?
