SEO tools are kind of like cars. Sure, Bugatti’s La Voiture Noire is a nice ride — but a Chevrolet Spark will get you from Point A to Point B too. In the same way, inexpensive SEO resources abound to help boost the quantity and quality of site traffic from search engines. And though you’ll likely get more functionality out of paid tools, there are plenty of alternate options to consider if your SEO budget is limited. (And, in many cases, even if it’s not.)
From Beam Us Up and Screaming Frog to SEO Minion, SEOquake, and more than two dozen others, check out our 35 favorite SEO tools. The best part? Every single one is free!

The Best Free Crawling and Indexing Tools
These tools come in handy when you want to understand how search engines are crawling your site and whether they are finding all of the great content you have created throughout — and, even more important, how to optimize your pages for it.

The Best Free Link Tools
Backlinks are key to SEO because they help reassure search engines like Google that your site has expertise, authority, and trust.
