6 pillars. One score. Every fix prioritised.
Every other free audit grades 1–2 things and calls it done. We grade the same surface area as a $500/mo enterprise SEO platform.

Technical SEO
Schema markup, canonical tags, sitemap, robots, redirects.
On-Page
Titles, meta descriptions, heading hierarchy, content depth.
Mobile
Mobile-first scoring with viewport, tap targets, font legibility.
Security & Trust
SSL, DNS health, SPF/DMARC, exposed emails, mixed content.
AI Readiness
Can ChatGPT, Perplexity & Gemini crawl, parse and cite your site?
