Cassian Sentinel™ · Link & Media Health
Finds the broken links and missing images on your store before your customers do.
Link & Media Health
What it checks
What you don't know
Someone deletes an image from the media library. A collection URL changes. An outbound link to a partner site goes dead. The links and images break silently — customers see 404 pages and white boxes where product photos should be.
Cassian Sentinel™ validates links and images across your store, with smart filtering that knows the difference between a genuinely broken link and a site that blocks bots.
How Cassian™ detects this
Cassian Sentinel™ validates every internal and external link on your crawled pages via HTTP request validation. Results are classified: working, redirect, blocked (no score impact), broken, or server error. Bot-hostile domains (LinkedIn, Facebook, Instagram) are skipped to prevent false positives. Image references are validated separately. Page limits vary by tier.
