I recommend PolyCola.com as a good search engine to compare Google and Yahoo results (as well as other search engines side-by-side). You can use it to check your rankings at a glance, pretty cool to me.
I've also been using http://www.twingine.no/ to the same effect. It does a similar side by side system, though it looks like polycola is a little more advanced. Regardless, both are helpful tools, thanks for the tip!
Yeah both are cool and I PolyCola (formerly GahooYoogle) has around a few years which is why they've had more time to perfect their engine. But yet & still not many people know about it. But hey it saves me a lot of time from going back & forth that's for sure!
Of course, these are in clear violation of the terms of service provided by the search engines.

etc.
Well how do you know that they haven't been specifically allowed to do so as you say?? I think PolyCola went through this stage several years back and have come to some type of agreement with the major engines to date - which it why they went through a big publicized name change a while back.
I found that polycola was incredibly helpful when doing keyword and niche research. You can easily see how google and yahoo are ranking pages and compare their strategies. In terms of personal searches, though, I stick with google.
I think that google still had a better Search result and services compared to it, simply it is establish and already tested by many users.
polycola.com is a tool which display Google and Yahoo result together.. Can not say its a SE and also no need to compare with it...All knows Google the best
