What It Audits

Everything a Search Engine Sees, in One Crawl

One free crawl surfaces every technical problem — metadata gaps to orphan pages to broken assets — ranked by impact.

Deep Technical Crawl

Spider up to 10,000 pages with configurable depth, subdomain scope and XML sitemap auto-discovery.

Diagnostic Issue Log

Every issue ranked by impact: duplicate titles, missing H1s, orphan pages, sitemap gaps, render-blocking scripts.

Page-Level Insights

Drill into any URL for its full anatomy — link graph, DOM depth, asset count, text ratio and per-entity schema validation.

AI Search Visibility

Check if ChatGPT-User, OAI-SearchBot, Googlebot and Google-Extended can index your site.

Search Console Sync

Connect once and enrich every crawl with real clicks, impressions and rankings — no extra tools.

AI-Powered Summaries

Gemini-powered summaries turn each crawl report into a plain-language, prioritised action plan.

CSV & XLSX Exports
