It is suggested you scan each link on your website atleast once every two weeks to keep track of stale links and repair them as needed.

Link validity fluctuates and some do not allow spidering, so before assuming all the displayed failed links are faulty, please check them. For the ones that come back as successful, these are 100% accurate at the time of scanning.

Scan URL:
Base URL:
*base URL is the directory your Scan URL resides in.  Example: www.yoursite.dom/this/test.html would have a base URL of www.yoursite.dom/this/ (ends in backslash). If you're scanning just the domain, use the same URL in both textboxes.
