GTrends SE checks if there are any pages from Web 2.0 sites in the Google search results for every keyword (when searching for an “exact match”). For this purpose it uses a list of domains stored in a text file.
To edit the list of Web 2.0 sites, open the GTrends SE installation directory (it’s “c:\Program Files\GTrends SE” by default) and locate the web20domains.txt file. This is a simple text file that you can open in any text editor, even Notepad. The file contains a list of domains – one domain per row (empty rows are ignored). Any changes you make to the file will take effect the next time you start GTrends SE.
One thing to note is that “example.com” will also match “www.example.com”, “abc.example.com” and so on.
