A page can return a perfectly healthy 200 OK status code while showing an error, a blank screen, or content injected by an attacker. Standard uptime checks miss this entirely. Keyword monitoring solves it by checking the actual content of the page.
Uppinger looks for a word or phrase that should always be present (like your product name) or one that should never appear (like "database error" or spam injected by a hack). If the expectation fails, you get an alert — even though the server still responds normally.
How Keyword Monitoring works
Add your URL and keyword
Choose a phrase that must be present, or one that must be absent, on the page.
We fetch and scan the page
On every check, Uppinger downloads the page and searches its content.
Detect silent failures
A missing keyword or an unexpected one means the page is broken or compromised.
Instant alerts
You are notified immediately so you can act before users or search engines notice.

Frequently asked questions
What is keyword monitoring?
Keyword monitoring checks the actual content of a web page for a required or forbidden word or phrase, catching failures that a simple status-code check would miss.
Why do I need it if I already have HTTP monitoring?
HTTP monitoring only checks the status code. A page can return 200 OK while showing an error or hacked content. Keyword monitoring inspects the content itself.
Can it detect a hacked website?
Yes. By alerting when forbidden text appears or expected text disappears, keyword monitoring is an effective early-warning signal for defacement and spam injection.
