Traffic Percentage ???

[JoeBlack]

What percentage of traffic is there between google and yahoo traffic for the same major keyword. Im trying to figure out the traffic ratio for say the keyword "free porn" in google to the keyword "free porn" in yahoo. Now "free porn" is just an example but other high terms can be used in its place.

Another question I have is for sites who are in the top 40 - 60 for high keywords. Do surfers search the 4th page to the 6th page or do they stop at 3rd. If you are on the 5th or 6th page do you still get decent traffic? This question is for both google and yahoo so any input would be good. Just trying to do a little reach search to figure out where I am and where I need to be.

Thanks for any help that is given.
