Differences in the Mainstream Search Engines
Knowing your “enemy” will go a long way in helping you understand why your website may be performing the way it is in a particular search engine. Search engine algorithms change constantly, some daily. There is no way to know exactly when or how to predict changes in a search engine, but there are trends to follow. There are some major factors that, even though they all weigh in their relevancy scores, each are weighted differently.

The breakdown of the market share of search queries that these six search engines currently control is listed below. These figures were taken from Forbes.com for August, 2005.
- Google: 37.3%, up from 36.5% in July
- Yahoo: 29.7% down from 30.3% in July
- MSN: 15.8% up from 15.5% in July
