Website SEO Tools — Free Audit & Optimization Tools
Ranking on Google starts with a healthy website. These free website SEO tools audit the technical foundations search engines care about — your meta tags, keyword usage, robots.txt, XML sitemap and schema markup — and help you fix the issues holding your pages back.
Every tool is free with no signup, and most run entirely in your browser, so your site's data stays yours. Start with the Meta Tags Analyzer to see a page the way Google sees it, then use the generators to build the files your site is missing.
