Some of the fastest-growing SaaS companies share a common strategy: free tools. HubSpot's Website Grader, Ahrefs' Backlink Checker, and Neil Patel's Ubersuggest all use free tools to drive massive organic traffic. Here's why it works.
Why Free Tools Work for SEO
Free tools earn natural backlinks — bloggers and journalists link to useful tools without being asked. They target action-oriented keywords ("youtube embed generator," "qr code generator") that indicate high intent. And they keep visitors on your site, building brand familiarity.
