Bing may drop their paginated search results for some search queries where they are confident that page one of the search results are “the most relevant results” for the query.
If you search for some long tail queries, for example searching for [specifications for black iphone 6 64GB] at the footer of page one of the search results in Bing, instead of finding links to more pages of results, you will see a message that reads:
We think these are the most relevant results for your search. We’ve omitted some lower-quality results.
To be fair, there is a hyperlink to “see all results,” even the results Bing itself admits were omitted because they may be “lower-quality results.”
