What page crawling tracks

Page crawl monitoring inspects important pages and resources for broken links, missing assets, mixed content, and release regressions.

Why it matters

Broken links, missing assets, and mixed content erode visitor trust and search quality. Crawling catches those issues after releases and content updates.

Broken links hurt UX and SEO

Missing assets make pages feel broken

Mixed content weakens HTTPS trust

Crawl findings help catch release regressions

How it works in DownCTL

Page crawling turns visible client-site quality issues into reviewable operations findings between uptime checks and deeper Lighthouse reporting.
