Where can I find some good SEO facts?
 

IE. What is the % of ppl who click on the paid advertisers as apposed to the generic listings.

What SE has the most searches? Who is 2nd and 3rd etc etc Just some good facts like that would be appreciated.

Google, MSN, Yahoo top se's

Users that click on paid ads, %1-%15 depending on SE / Term / Other

More more more!

i dont think anybody will share but i would like aproximate percent differences between #1, #2 and #3 places for clicks

What ztik said.

And I like MSN/AdCenter (despite their owners) because it offers really neat granular targeting... learn how to really *use* their features is my advice.
You can even target age groups, so if You're trying to sell home loans, You can choose to target just the group 30-50 something. They're not for adult though...

BOSS1: see what ztik said. And if You're doing mainstream, AdCenter is not about amount of clicks as much as it's about *quality* clicks - they pack the most value per click today.

Oh, (too late for editing) percentage estimates for BOSS1, very roughly (depends on what people are looking for also):

G: 50%
Y: 30%
M: 20%

There is no money is SEO. None. :)
