Site Audit — what we crawl and how often
Crawl cadence, what we check, how to interpret the severity scores, and how to exclude paths you don't want crawled.
Site Audit is a full technical SEO crawler that runs on a schedule and surfaces issues by severity, type, and trend. It's the same crawler design as Lighthouse + Screaming Frog combined, optimized for continuous monitoring rather than one-off scans.
What we crawl
- Every URL discoverable from your homepage + sitemap + internal links.
- Up to 100K URLs per project on Pro; unlimited on Enterprise.
- Each URL: HTTP status, headers, meta tags, structured data, internal links, image alts, canonical, hreflang, robots directives, page weight, Core Web Vitals (lab).
- Sitemap.xml itself: parses every entry, validates against the spec, confirms each URL is reachable.
Cadence
Default: weekly, on whatever day you created the project. You can override to daily on Pro, or on-demand at any time. Large sites (50K+ URLs) typically run weekly because a full crawl takes 6-12 hours.
Severity tiers
- Critical — broken canonicals, noindex on a page that should rank, 5xx responses, missing meta-robots on pages you don't want indexed.
- Warning — slow LCP, missing alt text on hero images, redirect chains > 2 hops, soft 404s.
- Notice — missing OG tags, oversized images, hreflang inconsistencies on multi-region sites.
Watch the trend more than the absolute number
Most sites have 100+ notices and that's fine. What matters is the delta — 12 new criticals appearing after a deploy is a signal to investigate. The audit page foregrounds this exact diff at the top.
Excluding paths
Project settings → Site Audit → Excluded paths. Accepts wildcards and respects your robots.txt by default. Common excludes: /admin/*, /preview/*, query-string filtered URLs that don't need to be crawled separately.
