plz do the search for "hotel galaxy kolkata" and check top 30 results
In the top 30 results, I'm seeing different TripAdvisor tlds
and cctlds showing up all together for 14 pages... searching on google.co.in from the San Francisco Bay Area, 10 results per page, no quotes.
Google is showing here many different data sorts... eg...
Hotel_Review and LocationPhotos from tripadvisor.in...
Hotel_Review from tripadvisor.com.my...
ShowUserReviews and ShowTopic from tripadvisor.com...
LocationPhotos from tripadvisor.com.sg...
ShowUserReviews from tripadvisor.com.au...
two different ShowUserReviews pages from tripadvisor.ca...
...etc etc etc.
The user reviews appear to paginated 4 reviews to a page, and Google is returning basically different content. I didn't count carefully, but I don't think I'm seeing more than two pages per domain.
Note that google.com does more or less the same thing, also with 14 results. I haven't checked carefully enough to see if it's the same pages ranking in both Googles.
I do remember results like this from google.com in the US some years back, with TripAdvisor more dominant than I felt one
company had a right to be, but never quite to this extent. No one TripAdvisor domain, though, is dominating... it's the set of international domains that is getting the multiple results.
