Adalysis automatically monitors all your Final URLs (Ad Final, Nobile Final, Keyword Final) and alerts you when it detects any downtime issues.  It will ping all URLs once a week and display a dashboard warning if any are found:

Clicking on the above warning will take you to the below screen showing all the broken URLs

You can view the Ads or keywords that currently use the reported broken URL


You can also check the current status of this page to confirm if it is indeed still unreachable:

Once you fix the broken URL, or correct the Ad/keyword that use it, you can remove it from the list above and report it as no longer broken by clicking on the relevant check symbol.
