Caijo audits your site's trust signals and gives you a prioritised list of credibility gaps to fix.
Low trust scores are often the hidden reason a well-structured site still isn't getting cited. CaijoBot checks for missing author schema and disconnected author bios, absent legal pages, E-E-A-T signals that are present but not connected to your structured data, and review markup that exists in HTML but isn't being read as schema. Free users see the trust score. PRO+ and AGENCY users get every gap identified with plain English fix instructions and a CiteReady passage for each Cornerstone Page that's being held back by a trust deficit.
