DoubleTrust - Combines Google & Yahoo! Authority Results

Story Text:

Ashish Gupta emailed to tell me about DoubleTrust which takes results from Yahoo! and Google and presents the intersection of those results ranking them by matching authorities...

From the email..

1. It is based on the simple premise that trusting two authorities is better than one. By presenting the intersection and non-intersection of Google and Yahoo very clearly, it shows the best results from their mutual agreement, and also the top sites which are not covered by each engine.

2. TrustRank: Meta-search has this problem of doing its own thing with results and taking control away from the user. TrustRank gives user control of the ordering of the common results by defining their own trust level for each engine. A weighted score is then computed using the user's trust options.

3. Compact Interface: Highly compact but convenient representation of around 80 results on page using tables and DHTML, gives the user a quick view of the results and allows quick selection and searching, saving time.

4. More freedom to choose: By presenting important properties of each search page like size, domain etc in a clear comparative representation, DoubleTrust allows the user freedom in choosing the results using other than just ranking. For example, looking for an essay on American History , one may prefer pages with more content say 50K than the smaller pages. A clear comparison using graphics and colors gives the user an immediate way to compare these other properties, which are usually buried in conventional search results.

If you like Search toys, it's kinda fun...


nice, thanks.

At first I thought DoubleTrust would just confuse things, because I long ago stopped attempting to achieve a compromise site ranking on both Y and G. Then I saw how a G-pseudo-penalized site showed rather conspicuously on the DoubleTrust results page - #1 for the combined, #1 in Y!, and not visible in G (although it was buried in there somewhere). Examination of the G serps showed many irrelevant pages, and Y! was very good quality.

I think this tool can be very useful for a birds-eye-view of how badly G is broken for your particular kw, which enables planning.

I have to say the twin guitar image is a nice touch... you don't find gratuitous rock-on grapics on "corporate" websites.

One big question: as with all query tools, how long will it continue to work?

Google and Y!

Thanks Andrews for your comments. When I first though of writing DoubleTrust, my initial curiosity was also to explore what you mentioned, and didn't know how things would turn out. It IS interesting to see how they differ and intersect. I was a bit suprised in the beginning about the differences and also how many sites in the differences were quite relevant to me in both the OPRHAN tables.

I am still interested in understanding more statistics from the results, besides just the intersection and non-intersection of the results. Like the domain coverage analysis which is already there.

Does anybody have any suggestions for comparative statistics ?

over time

If you pubished lists of commonalities for the top competitive keywords over time, such that CHANGES stood out like a sore thumb, I bet your report page would be very popular.

For example, it would highlight when sites were orphaned in one engine after having been competitive in both, for a certian niche market, in effect hinting an "event" had taken place (manual intervention, filter adjustment, etc) whcih would be very helpful to other webmasters in that space.
