How to schedule recurring site audits
Navigate to the SEO --> Site Auditor campaign dashboard for the campaign in question.
Then, click the settings button at the upper right corner of your screen. In the slide out window that appears, click the "edit" link next to the "Schedule" option:
In the new window that opens, you'll be able to select the frequency of automated audits, disable recurring audits, as well as select the time and day of the week or month on which your audits will run.
In the example above, your audits would now automatically run every week on Wednesday at 2:30pm (EDT).
