There are 4 modes for site analysis available at Ahrefs:
Domain with all its subdomains
Domain without subdomains
An example of domain is example.net. It will search for pages and its data based on that domain. In the example, http://example.net/standards/codecs, it will still only search for pages/data in the domain, example.net.
An example of Prefix is https://example.net/cloud. It will search for all related data in the folder cloud.
An example of exact URL is http://www.example.net/products.html. It will search for all data pertaining to the URL only.
