Search engine market shares
According to searchengineland.com, all search engines (Google, Yahoo, and Microsoft) have grown over 2008 and 2009 based on Comscore, Nielsen, Complete, and Hitwise that are major rating service companies. Globally Google has 81.09%, Yahoo 10.45%, MSN 3.03%, AOL 2% (Net Application data from buildtelligence.com; not sure when these data were collected). Statowl.com’s data are more relevant because it has date information (of latest six months of August 2009 – Jan 2010). Google has 85.34%, Yahoo 6.13%, Bing 5.03%, and AOL 2.41%. Based on these number, it is wise to invest Google adwords to reach most potential clients and traffics.
Referrals are critical for decision making. This makes MySpace, Facebook and LinkedIn more attractive in Today’s environment.
