Search Engine Loyalty
It turns out that searchers are more than willing to use multiple search engines according to Nielsen/NetRatings. In January 2005 Google reported 71 million unique searchers, 58 percent of which had used another search engine. Yahoo’s percentage was higher – 71 percent.
So how does this affect your search engine optimization efforts? It shows that you cannot afford to only concentrate on the rankings you are receiving in one search engine. Currently the market is dominated by Google, Yahoo and MSN with several other engines sharing a small percentage of traffic. And all these search engines have different methods of drawing their results giving different levels of importance to content, links, page elements, etc.
Monitoring your search results across multiple search engines for multiple keywords gives you a truer picture of how well you are ranked. By not putting all your eggs in one basket you can reach more of your targeted market.
