FAQ

Checker questions, answered

What's free, what's checked, and when you need the full-site audit instead.

Yes — paste any public URL and scan without an account. Anonymous users get 2 checks per day. Registered users get more daily checks and scan history.

Each check returns a status and a plain-language fix — e.g. a duplicate title tells you which canonical to consolidate on, a schema error shows the offending field. No jargon, no raw data dumps.

Anything site-wide. Broken internal link chains, orphan pages, duplicate sets across pages and sitemap mismatches need every page — that is the full-site audit. The checker is the front door; the audit is the whole visit.

Public URLs only, no authentication. For React/Vue/Angular single-page apps that render content via JavaScript, the checker scores the raw HTML as any SEO crawler would — if headings and body text are absent from the initial HTML, those checks count as failed (content is invisible to crawlers). This matches what SEMrush, SEOptimer and Seobility report. Use server-side rendering (SSR) or static pre-rendering so content exists in the initial HTML response.

The checker scores a single URL in seconds with no account. The full audit crawls every page your site exposes, runs cross-page checks (duplicates, orphans, broken links), and returns a deduplicated, impact-prioritized roadmap. Use both for different jobs.
