When people on the street use phrases like 'google for it'
Heh, people used to say "xerox it" and Xerox had to fight hard to make people use "photocopy" because they were terrified at the thought of word "xerox" becoming so common that they will lose their trademark on it. ;)
Engine - thank goodness for your wife. She may be powering all of our Yahoo/MSN volumes.
Google is definitely king in the UK - regardless of the higher prices and lower conversion rates, there's no point putting much effort into Yahoo and Live because the volume isn't there. Its a shame, because I'd really like to play with features like MSN's demographic targeting, but it isn't really worth that effort.
Everything I do, I do on Google first, refine it, and then apply to MSN/Yahoo later.
