Once you're satisfied with the URL and extension settings, you may hit the
Update and GO button to begin a walk of your site.
A walk will be started in the background and you will be taken to the
Walk Status page. This page will show you the status of the walk
in progress and indicate when the walk is complete. This page will
automatically refresh every 10 seconds with the latest progress
information until the walk is complete. When the walk is complete you
will see a summary of errors.
