Sitebulb has a range of 'global settings' which act as the default settings for every new audit you start. From the top navigation menu, choose the 'Settings' option.
From here, the 'Excluded External URLs' tab allows you to exclude Sitebulb from scheduling and crawling specific external URLs, by defining domains, paths and patterns.
You will find a number of values pre-set, which are mostly used to stop Sitebulb crawling thousands of irrelevant URLs (e.g. social share linking URLs). If you want to stop Sitebulb from crawling external URLs or domains, add them to these lists.
By adding domains to the list of Excluded Hosts you will stop any URLs that reside on these domains from being scheduled and checked by the Sitebulb crawler.
Adding in 'example.com' would exclude:
If you wanted to ONLY exclude a specific subdomain, just add that subdomain only (e.g. https://blog.example.com).
By adding paths to the list of Excluded Paths you will stop any external URLs that include these paths from being scheduled and checked by the Sitebulb crawler.
Adding in 'tweet' would exclude:
You can limit this to make it more specific, for instance adding 'tweet.php' will only match URLs with that specific string.
