Broken link checker that only tells you when a new link breaks
Verify a site you own. Mortise crawls it, stores a baseline, and skips the noise of known 404s. Free for one site. Pro adds schedules and alerts.
One job
Find broken links on your website without a desktop SEO suite and without being paged for the same dead URL every week.
1. Prove you own it
Add a file, meta tag, or DNS TXT record. No crawl until that check passes.
2. Baseline, then watch
The first crawl never alerts. Later crawls compare status history.
3. New breaks only
A link must fail twice as 404 or 410 before it counts. Timeouts are not pages.
Built for owners, not audits
If you need a content diff on one public URL, use SignalWatch. If you need budgets without bank linking, use LiteWork Finance. Mortise only watches link health on sites you verify.
