CheckSEO

Free SEO checkers and full-site audits: meta, headings, speed, links. No signup.

CheckSEO is a free, no-signup SEO toolbox built by Hykvra. It bundles 84 checkers into one search box: on-page SEO (meta tags, headings, keyword density, canonical, robots), technical SEO (status codes, redirects, sitemap, speed), structured data and social sharing previews, domain and DNS lookups, developer utilities like JSON and minifiers, and YouTube tools. A full-site overview crawls your pages and flags what to fix first. There are no accounts, no limits on the free tools and no agency upsell in the way — just paste a URL. CheckSEO was built for founders, freelancers and small agencies in India and worldwide who need quick, trustworthy checks before a launch, a client call or a Google update. It is the SEO companion to Hyklinks, Hykvra's free directory database for backlinks.
