The Crawler rules menu allows you create rules to control which pages the crawler visits. They can be based on excluding/including specific domains, subdomains or directories. If the structure of your website hierarchy is not suitable then you can also base rules on data within the HTML. For example you could exclude every page that has a title containing ‘internal only’.
