Dogpile came out with an update of its study about how there's very little overlap among search top search results for the major engines. Here are the highlighted stats:
- Only 0.6% of 776,435 first-page search results were the same across the top four Web
search engines
- Between 38% and 46% of all searches fail to elicit a click on a first-page search result,
don’t meet users needs and drive users to try additional
engines.
- Web searchers on
average use three search engines a month
- Search result
rankings differ significantly across major search engines; only 3.6 percent of
the number-one ranked, non-sponsored search results were the same across all
search engines in a given query
This is all interesting research, but I'm not sold on their analysis. Consider this quote from the release:
"This study reinforces what we at InfoSpace have long known – often users do not find the results they need with any single search engine. Metasearch offers the most robust and efficient search solution to meet their needs," said Rod Diefendorf, vice president of online and local search at InfoSpace. "With less than one percent overlap in first page results, there is great value to using a metasearch engine like Dogpile.com to quickly comb through multiple search engines at once for the most relevant results."
What Dogpile has yet to convince me of is that it offers the most relevant results simply by aggregating everything. Let’s say Engine 1 is extremely
relevant, while Engines 2 and 3 are moderately relevant and Engine 4 is
practically irrelevant in terms of the quality of their results. Then Dogpile,
by culling results from all four engines, actually dilutes the relevance of
Engine 1.
If Engine 1 is Google, then Dogpile would be a step down for most searchers given Google's roughly 60% share of search queries. If Engine 1 is Ask.com, Dogpile would be a step up for the roughly 95% of searches conducted on other engines.
Here's what I'd like to find out from Dogpile: If "between 38% and 46% of all searches fail to elicit a click on a first-page search result," do Dogpile searches perform any better?
