Meta Searching for Relevancy, Using Your Own Rules

Myriad Search is a new tool from Aaron Wall's Free Open Source SEO Tools site that allows you to play around with search results from Ask Jeeves, Google, MSN Search and Yahoo. It's a meta search tool that displays information about the relative ranking of sites in each underlying engine, and calculates an "authority score" based on those rankings—a potentially useful service for doing competitive SEO work.

Myriad Search also allows you to give more prominence to your favorite search engine, and dial down the importance of engines you don't like. It's an intriguing idea, and I've got more about the service in today's SearchDay article, Myriad Search: Meta Search Your Way.
