Look a little further, and market research shows that people actually use four main search engines for 99.99% of their searches: Google, Yahoo!, MSN, and Ask.com (in that order). But in my travels as a Search Engine Optimizer (SEO), I have discovered that in that .01% lies a vast multitude of the most innovative and creative search engines you have never seen. So many, in fact, that I have had to limit my list of the very best ones to a mere 100.
I didn’t realize until now just how many search engines there were on the web. A lot of them offer their own twist on things, so it’s good to test a bunch out before settling on one. The author touches on the backend of the search engine world and then throws the huge list right at you. It’s best you set aside some time before going through them all. It may take a while.
