Why are people going to these websites, newspapers and blogs to be exposed to those ads that generate revenue if they are clicked on, they are seeking information.

That is why where an ad revenue sharing internet content operations fight and work to rise to the top of search results.
Something happened, because the way search engines find the information you seek is to find information that contain the terms you typed into the search area.
