In recent years, search market share has remained mostly unchanged – for much of the world, it’s Google followed by every other search engine (in the U. the “Big 5” search engines consist of Google, Bing, Yahoo, and AOL, which combine for hundreds of billions of searches every month).Meanwhile, many of the players have consolidated or have become footnotes in history.
The majority of Google’s revenue is derived from their Ad Words and Ad Sense programs.
In fact, advertising accounts for more than 95 percent of Google’s earnings.
In addition, Baidu offers PPC which, similar to Ad Words, is displayed at the top or right of the standard results.
One could argue that the existence of the PPC-like results further confuses the users clicking on the standard results area into believing they are organically generated.
Search Engine Watch has been covering search engines since June 1997 and has watched the industry evolve to its current state.
