Cause
This error can be found in your Location Fail Log for the website uptime monitors that you have configured keyword monitoring for and the specified keyword that you configured our system to look for is not found on the monitored target page.
Our system will look for the specified keyword only in the HTML source code of the monitored page, without loading any extra scripts/css/images/etc found on that page.
Fix
Please make sure that your monitored page has the designated keyword in its HTML source code.
If your website loads its content dynamically using Javascript, then the keyword has to be found on the initial page and not on the content that’s being dynamically loaded by any scripts.
