Counting the number of responses to a web search

[GoldfishLord]

This is an example of why I don't think counting the number of responses to a web search is a valid way of learning English!! It's search "on Google", or "Google it".

I'd like to know what exactly the red part means.

I guess responses means 'results'. When you do a Google search, you get a certain number of results.
