What we check
14 modules, every one a real check rather than a checklist item. 12 run on your free scan; Core Web Vitals and Backlinks & authority need a free account, because they cost us money to run.
Security & HTTPS
Certificate validity and expiry, HTTP→HTTPS upgrade, HSTS, CSP, and mixed-content scanning.
Crawlability
robots.txt rules, XML sitemap discovery and validity, and whether the two agree with each other.
Core Web Vitals
Real Lighthouse metrics via PageSpeed Insights — LCP, CLS, TBT and the performance score per page.
Broken links
Internal and external links that 404, redirect chains, and the pages that point at them.
Meta tags
Missing, duplicated, truncated or misplaced titles and descriptions across every crawled page.
Heading structure
Missing H1s, multiple H1s, and heading levels that skip — the outline search engines actually read.
Internal linking
Orphan pages, link depth, and how authority flows through your site's internal link graph.
Thin & duplicate content
Pages too short to rank and near-duplicate content competing with itself.
Images
Missing alt text, oversized files, and formats costing you load time.
Accessibility
Contrast, labels, and landmark issues that hurt both users and rankings.
Site health
Status codes, canonical tags, indexability, and the aggregate score that ties it all together.
AI visibility
Whether ChatGPT, Claude and Perplexity can reach, read and cite you — a site can rank in Google and still be invisible to them.
Backlinks & authority
Who links to you, the anchors they use, link rot, and spam signals across your inbound profile.
Local SEO & Google Maps
LocalBusiness schema, name/address/phone, geo-coordinates and opening hours — everything Google needs to rank you in Maps and the local pack.
