Catch missing content before your users notice
SignalDocks fetches your page and scans the HTML body for a keyword. If it disappears — or appears unexpectedly — you get alerted.
Free plan available · No credit card required
Presence & absence checks
Alert when a keyword is missing (your main CTA, a product name) or when it appears (an error message, a maintenance notice).
Full HTML body scan
SignalDocks reads the full rendered HTML — not just visible text — so it catches keywords hidden in meta tags or data attributes.
Catch silent failures
Some servers return HTTP 200 even on error pages. Keyword monitoring catches these edge cases that status-code checks miss.

We fetch and scan
On every check, SignalDocks performs a GET request and searches the raw HTML body for your keyword.
Alert on mismatch
If the keyword state doesn't match your rule, an incident is created and your channels are notified.
