Custom Checks are rules that can be set, allowing you to create your own checks within content. These checks will be made when DubBot next crawls your site. Checks can be made with regular text, Link Text, Link URL, XPath, CSS, and Regular Expression.
In order to access the Custom Checks interface, got to Account Settings --> Custom Checks
Once you've access Custom Checks, select "New Custom Check" in order to create one of your own.
When adding a Custom Check, you'll need to name it first. From there, you'll be able to determine different rules, and set up how DubBot will conduct the check during its crawls. Multiple levels of rules can be set up. Select "Add Rule" if you want to add levels. Once you have added your rules, make sure to save your check.
DubBot has a library of pre-written checks on our Knowledge Base. Let us know if you have something you want to do, and we can help you out.
