Why free tools?

Every tool runs the exact same crawler the full RankForge audit uses. Instead of handing you the whole report, each one zooms in on a single SEO problem and answers it fast. Run one to scratch an itch — or create a free account to get the complete structural audit, with the specific link fixes for every issue at once.
