A real crawler reads your homepage
Our crawler fetches the page and runs its checks — the same technology used by paid SEO platforms.
Instant
Read the fixes, not the data
One health score, your Domain Trust, and each finding in three plain lines: what is wrong, what it costs, what to change.
120+ checks, 6 results you actually read.
The crawler runs the full battery; you only see what needs your attention, ranked by severity.
Search appearance
Title, meta description and H1 — shown verbatim, with lengths, exactly as Google reads them.
Site health score
SE Ranking's 0-100 score for the page, computed by their crawler and shown unadjusted.
Security basics
HTTPS, mixed content and redirect hygiene — the checks browsers warn your visitors about.
Mobile readiness
Viewport setup plus Google's real-user Core Web Vitals for phone and desktop, where Google has them.
Domain authority
Domain Trust, backlinks, linking domains and how many of your pages Google has indexed.
Speed signals
Load time, oversized CSS and JavaScript, and anything else slowing the first paint.
