Domain Specific Search Engines
Nov 13th, 2007 by yigber
News flash: The web is not just Google. There are many other crucial information sources (a.k.a search engines) available out there that serve a purpose different than What Google’s engine is meant for. For example, if you want to find a job, don’t search Google. Use instead the search engine that specializes in that kind of information. If you are looking for a blog post, don’t search the regular Google search engine. Use Google’s Blogsearch instead.
It may sound obvious, and you may recognize all the engines listed below, but how often are you really using them ? My bet is that 95% of online users just go straight to the obvious option without considering other engines that will yield much better results for their search.
Here is a list of the sources I can think about, classified by the vertical or attribute that characterizes them.
Soon enough I’ll linkify them to make the list more convenient. Please put a comment below about more engines and services that you think are missing.
