WatchPresent or absent
Alert when a page stops containing expected text (e.g. “Add to cart”) or starts containing text it should not (e.g. “Exception”).
Keyword monitoring
Catch the errors a 200 response hides
A page can return HTTP 200 and still be broken — a stack trace, an empty cart, a login that vanished. WatchControl checks the actual content for the text that should (or should not) be there.
Soft-error detection
Catch the 200-but-wrong failures plain uptime checks miss — error pages, blank templates and broken renders.
Defacement & drift
Notice unexpected content changes on important pages, not just whether they load.
Instant alerts
Email and webhook on every plan, plus SMS, with re-notify so nothing slips through.
FAQ
Frequently asked questions
What is keyword (content) monitoring?
It checks that a page contains — or no longer contains — specific text, so you catch broken pages that still return HTTP 200.
Can it alert when text disappears?
Yes — you can alert on text that should be present going missing, or on unexpected text like an error message appearing.
Why not just check the status code?
Because a page can return 200 while showing an error or empty content. Keyword checks catch those silent failures.
Is keyword monitoring free?
Yes — keyword/content is one of the nine monitor types on every plan.
