Notification on broken internal links

What you don't know

Products get archived. Collections get reorganised. The links break silently.

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.
