Fixed the reds? The two things no free checker can see: what people actually search for and who links to you. That's the paid-index territory — the affordable route we use:
🔑 Check search volumes — KWFinder
🔗 See any site's backlinks — LinkMiner
Affiliate links · free tier available · supports these free tools
What this checks: on-page and technical signals from the live page, robots.txt, sitemap, security headers, AI-crawler access, plus free authority data (Open PageRank, Common-Crawl based) and Google Lighthouse. It does not check backlink lists or keyword volumes — those need paid indexes; for those we use KWFinder (volumes) and LinkMiner (backlinks) — affiliate links, free tier available. New here? Read how to check a page's SEO for free. Related tools: Meta Tag Generator, Sitemap Generator, Keyword Density Checker, Word Counter.
Fixing the social card? The Social row counts the page's Open Graph tags. To write or correct them, use the Facebook link preview generator or the meta tag generator, then re-run this check on the live URL.
