Aaron is at it again. This time he has rolled out a handy meta search tool for anyone that is constantly comparing results among the big four.
MyriadSearch provides results for Google, Yahoo!, MSN and Ask Jeeves.
You can also weight the responses in the All category that mixes the results through the percentage of position a given site has through all four engines - this way you can assess how those engines impact in the mix.
It is another tool I will spend a lot of time using. Thanks mate!
