# AuditLamp > AuditLamp is an AI Visibility Platform. It reads a website the way Google, ChatGPT, Claude, and Gemini actually read it, scores it against 164 graded checks, and tells the owner, in plain language, exactly why they are invisible to AI search and what to change first. The free scan gives the diagnosis; the paid tiers give the cure, the monitoring, and the proof it worked. AuditLamp is built as one shared audit engine behind a web app and native apps. It fetches the real site (the real robots.txt, the real schema, the real rendered HTML) rather than estimating from a sampled crawl. It is an honesty brand: it never fakes social proof, never claims unbuilt features, and is blunt about the site without being contemptuous of the person. ## Pages - [Home](https://auditlamp.com/): What AuditLamp is, how search moved to SEO + AEO + GEO, and why visibility breaks silently. - [How it works](https://auditlamp.com/how-it-works): three-step story, five pillars, free vs paid, AI crawlers in plain English. - [What we check](https://auditlamp.com/what-we-check): 164 graded checks catalog by pillar with named check ids. - [Methodology](https://auditlamp.com/methodology): how the grade is made: 187 checks run, 164 graded, 70/30 on-page/Vibe blend, severity and cap rules, sources per check, honest limits of a passive scan. - [AuditLamp vs Ahrefs](https://auditlamp.com/auditlamp-vs-ahrefs): honest comparison; research suite vs plain-language AI visibility audit, who should use which. - [AuditLamp vs Semrush](https://auditlamp.com/auditlamp-vs-semrush): honest comparison; all-in-one marketing suite vs one focused audit with flat pricing. - [AuditLamp vs Screaming Frog](https://auditlamp.com/auditlamp-vs-screaming-frog): honest comparison; the pro's desktop crawler vs hosted graded verdicts in plain language. - [Readiness vs monitoring](https://auditlamp.com/readiness-vs-monitoring): eligibility audit vs ChatGPT citation trackers (different jobs). - [AI bot policy](https://auditlamp.com/ai-bot-policy): training vs search bots, three posture templates (SMB, publisher, SaaS docs), free scan to verify. - [Run an audit](https://auditlamp.com/app): Paste any URL for a free Visibility Scan of the whole site, up to 150 pages: every failing check named, worst first. - [Guides](https://auditlamp.com/learn): 157 plain-English guides, fixes and definitions covering AEO, GEO, local search folklore, and getting cited by ChatGPT, Claude, Gemini and AI Overviews, all grounded in official documentation. - [Free tools](https://auditlamp.com/tools/): 15 single-purpose checkers and generators: AI crawler access, schema, llms.txt, robots.txt, answer readiness, meta tags, snippet preview, score badge and more.

Live per-link verification and competitor landscape run on the paid tier. - Real rankings and traffic: average position, clicks, impressions and ranking queries straight from Google Search Console once the owner connects it, with weekly tracking snapshots and a 60-day before and after report. - Speed: real-user Core Web Vitals (CrUX field data) plus Lighthouse lab runs when the PageSpeed feed is connected. - AI visibility: llms.txt, answer-first structure, AI Overviews eligibility and extractable tables run on every scan; deeper entity and citability analysis runs when the AI feed is connected. - Fixes and proof: paste-ready generated JSON-LD, robots.txt and llms.txt on every audit, AI-written fixes when connected, score history per site, shareable report links, and an embeddable score badge. ## How AuditLamp ranks the damage - Gate: can a search crawler or an AI bot even reach and index you. A failure here voids everything below it. - Core: when someone searches what you sell, do you answer it better than the page ranking above you. - Amplifier: edges that lift you once the core is solid. - Hygiene: small leaks that quietly drain the authority you earned. ## What AuditLamp is honest about AuditLamp reports an on-page readiness score, not a ranking prediction. It does not measure your live rankings, your backlinks, or the competition above you unless those data feeds are connected. A clean on-page score is necessary, not sufficient.
