Not really a failure since I still believe in the idea and use it. But the project has been a failure as I was unable to get it across to the users.

I started with http://fefoo.com some 4 years back and finally launched it one and half year ago. I got some good initial feedback but almost very little coverage in blogs or twitter.

I completely failed in promoting it to the target audience. Since it looks like Google the comparison would inevitably come up and most "bloggers" would not even give it a second chance. It was for people who use more than one search engine, but without the right promotion and zero marketing skills it almost never got any coverage.

Its still not dead but I am keeping it alive as I use it and a few hundred people seem to use it.

Interesting. I quite like that.

To me the most useful feature is the in site toolbar with the buttons expanded that just allows you to quickly switch between different sites results sets.

I suspect though that for 99% of users Google is all they ever touch, and the other 1% use a browser toolbar of some kind to redirect their searches. After all, in FF it's only 1 click and an enter keypress to switch to a different engine (assuming you've got the ones you want setup).

Have you thought about displaying multiple results side by side (or even interleaved)?

I was sort of expecting to see multiple results too, but it's a bit harder to execute on that in a user-friendly way. An easier alternative may be encouraging the user to check other pages by saying something like:

"More results relevant to your search: Bing (20,000) | Yahoo (13,450), AOL (3450) ..." etc.

Or using async calls for conducting the same search on an alternate engine while the user is still reviewing the first set of results, and showing just a peek to the new set of results...
