Disavow.ai vs Preuve AI

Every website picks up backlinks it didn't ask for — spam networks, link farms, scraper sites. When they cause a Google penalty or tank your rankings, you need to act fast. Disavow.ai scans your backlink profile, classifies every linking domain as clean, suspicious, or toxic using a 4-layer Smart Risk Engine, and generates the exact file Google needs to ignore the bad ones. Toxic domains are grouped into plain-English categories — Spam & Link Farms, Private Blog Networks, Known Spam Patterns, Risky Extensions, and Near-Zero Authority — each showing exactly why it was flagged. No SEO jargon, no black-box scores. Free tier lets you scan and see 15 backlinks. Pro at $39/mo gives you unlimited backlinks, full export, and weekly auto-scans. That's 70% less than Semrush for the same core functionality.
