Why use these free SEO tools?
Most paid SEO suites bundle features you don't need on day one. These free SEO tools cover the fundamentals — a SERP preview, a keyword density checker, a robots.txt generator, a schema markup generator — without an account or credit card. Each one does a single job and gives you a usable result in under a minute.
They also work well as a daily complement to your existing stack. Use the SERP preview before publishing, run the keyword density checker on every new post, regenerate your robots.txt the day you ship a new section, and drop schema markup on pages where rich results matter. That's the loop most SEOs run.
Once you outgrow the basics — when you want keyword research connected to your real search data, AI-powered content briefs, competitor gap analysis, or automated rank tracking — RankWhiz connects to your Google Search Console and gives you recommendations specific to your site.
