Different engine different SEO needed
“OverlapAnalysis :: Different Engines, Different Results”, meta-search engine Dogpile and researchers from Penn State and the University of Pittsburgh, examined search results from over 12,500 random, user-entered search queries on Google, Yahoo, MSN and Ask Jeeves. Of the 12,500 inquiries, which produced a total of 485,460 results, only 5,301 or 1.1% produced the same first page results across all engines. The significance of this change over the past year and a half magnified when compared with a similar study released by Dogpile in May, which showed a 3% overlap in total search results."Executive Summary 1 page PDF
Chris Sherman comments: Search Engine Results Continuing to Diverge
"84.9% of total results are unique to one engine
11.4% of total results were shared by any two engines
2.6% of total results were shared by any three engines
1.1% of total results were shared by any four engines
The implications of these findings are significant for both searchers and marketers. Searchers relying on a single search engine are missing a vast swath of web content that they could easily find simply by trying their queries on other engines. And marketers targeting a single search engine in their optimization efforts are effectively abandoning a potentially huge amount of traffic from other sources.
Just how unique are the results on each engine? On average:
73.9% of Ask Jeeves first page results were unique to Ask Jeeves
71.2% of Yahoo first page results were unique to Yahoo
70.8% of MSN search first page results were unique to MSN search
66.4% of Google first page results were unique to Google
This suggests that opportunities continue to abound for search marketers to gain exposure despite increasing competition among advertisers, particularly for less commonly used "search tail" terms."
