If you are an internet marketer, you know the importance of the major search engines. If you look at your referral logs, chances are over fifty percent of your web site’s traffic comes from Google, Yahoo and MSN. Because the major search engines send so much traffic, the majority of search engine optimization efforts are targeted at these three search engines. Normally, if your web site is performing well in these three search engines, it will also perform well in the second and third tier search engines.
