Authority Finder is another free search tool created by my friend Mike.
I wanted to create a tool which cross compared the search results from the major search engines to find the most authoritative results for a query (hence the name authority finder).
After a bit of thinking about it I realized with a few tweaks the tool could also double as a meta search engine and sorta like a share of voice tool (although an incomplete share of voice tool as it does not factor in paid listings and there are a ton of variables that go into who searches for what where).
A beta of the tool exists at Myriad Search.com.
Currently Myriad works with the Yahoo! & Google APIs. It queries MSN's search RSS feeds, but will be shifted over to their API sometime today or tomorrow at the latest.
I do not believe Ask has an API. I have sent mutliple emails to Ask to see if it was ok to include their search in the tool and they have not yet responded. Most of the stuff on their TOS talked about commercial use, and this tool is totally free. If they are unhappy with the tool querying Ask I will quickly remove Ask from it.
I have not yet released the source code since I will be changing out the MSN piece today and I still am somewhat uncertain as to whether or not Ask will care, although I am hoping they think it is ok. If not they can email me at seobook@gmail.com.
In the tools section I posted more in depth information about the features of Authority Finder.
Please let me know what you think.
