I would like to find out what the average click rate is for each of
the top ten positions.  For example if you search on "day rtading"
what % of clicks go to each position (1st .. 2nd.. 3rd..4th.. etc. 
Also what % of overall clicks are on teh first page of a search.

Do you need specific figures from a search engine like Google (might
be hard to find) or would click-through figures from a general study
on web usage be okay?

Also, pay-per-click search engines are likely to provide such
information, would they qualify?

it does not have to be serach engine spacific (google, yahoo etc) but
it does have to cover only search engins because i wan tto see
performance by rank.  PPC is fine as well.. I am sure distribution of
clicks is similar across all search engines.

OK.. Lets look at this instead.. How much is spent on search engine
pay per click advertising?

I knew I had seen it somewhere... When placing a PPC ad at Kanoodle,
they tell you that:

"The #1 Listing typically receives 2.5 more clicks than the #2 listing
and 4 times the amount of clicks as the number 3 listing."

I figure that would apply for all search engines. I was unable to
locate any serious study on the subject, although I have read one or
two of a few years ago.

I recall that the bottom listing always does well. On my websites,
when I make a list of links, my top four favorites on a topic get
placed in this order so that they will get noticed more... 1st, 2nd,
3rd, last.
