We know you might find this hard to believe, but Google is not the only search engine out there. No really. There are others. You might even have heard of a few, like Yahoo!, MSN, Ask, and even the oldie, but goody AltaVista.

SearchBoth is a website that lets you search multiple sites at once. But unlike Dogpile, SearchBoth doesn't spit out all the results in a single stream. Instead, you can compare your results side by side.

As you might guess from the search engine's name, you used to have access to just two sites: Google and Yahoo!. This month the company added support for more services, including all those listed above and MetaCrawler, LookSmart and WebCrawler to boot. There's also a new travel search feature that lets you compares results from several top travel sites and a yellowpages v. superpages online phone book faceoff.
