        //2. we could count domain, and see if it is > some set cut off (more options)
        //2.1 if we do that we should decide if count should be reset when a differnt domain is found

        //3. we could process domain and allow a varied level of url to count eg:
        //en.wikipedia.org vs de.wikipedia.org
        //4. the alternative to that would be just to strip www from the front, maybe some other common ones
