# AuditZap

> AI-powered website audit tool that checks SEO, performance, Core Web Vitals, security, and AI search visibility on any website, then returns fix instructions prioritised by estimated revenue impact.

AuditZap crawls a site (up to 100 pages on Pro, 250 on Agency, 10 on the free plan) and runs 40 checks across five categories - Critical, Performance, SEO, Quick Wins, and AI Visibility (answer-engine visibility: llms.txt, AI crawler access, citation and answer schema). Every failing check comes with a plain-English, CMS-aware fix instruction. The free tier scans all 40 checks with full detail on the 9 critical checks plus one AI fix per audit; Pro ($29/month or $249/year) unlocks AI fixes for every issue and clean PDF exports; Agency ($79/month) adds white-label PDF reports, an embeddable lead-capture audit widget, and 250 audits a day. There are also free standalone tools with no signup.
