Which search engine do you use?

Google always.

google and its regional variations. google is the default option pretty much but why not use other regional ones as well, esp if you are working in foreign markets where google is in some (yes rare but still) cases not even considered most popular search engine. russian yandex comes to mind here. research for your niche and get some more se's because if everyone picks only google - how are we going to get out of google monopoly then?

I use Google.

For everyday search, I generally use Google. For comparison search like when I want to compare my rankings in different engines side by side, I use polycola.com

I use Google, Yahoo and MSN but mostly Google.

Gooooooooooogle

Google is my best. very easy to rank my websites there.

Start Page is a search engine that does not keep track of your activity. It is ideal for those who believe the privacy is one of the foundations of freedom.

Google mostly, then Yahoo.

Google is favorite and I think every SEO or any visitor will vote for this..

Have always used google. I have heard google has search tricks that you can use in the search bar. If you google it im sure you can find a whole list of them.

Google mainly for SEO.. but I do use Bing sometimes...
