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?
