SERP means how many new visitors?

SERP equals what percent for search term

[gford]

I have been asked by a potential new client to come up with this infomartion for his board of directors if at all possible. So I am asking the SEO community for help!

Does anyone know of any papers/articles/threads/info that discuss how your SERP (and even more to the point your exact position in the top 20 resuts, position 1 thru 20) converts to # of visitors in a percentage basis?

For example. I have a search term that occurs 10,000 times per month as reported by overture (And is google roughly 10x overture by most peoples estimates?).

If I am the 20th result for this, what % of those 10,000 searches would I get?

If I am the 10th results for this, what %?

and so on to

If I am the 1st result for this, what %?

I realize this isn't an exact science but if anyone knows of research results in this area it would be a HUGE HELP to me.

Thanks!

OK, I'll bite.

Of course, there is no completely correct answer. It will vary for different search terms, how competitive they are, how much junk/spam is high in the SERPs and how enticing your title and blurb are versus other sites. Others will likely disagree mightily, and are invited to do so.

20th: 1% (if lucky)

10th: 9%

1st: 70% or more.

Your mileage may vary.

You shouldn't concentrate on the % of visitors coming from a certain position in the SERP.

The real question is: How many of them will perform a required action (conversion)such as to buy products,or to ask info?

Well the problem is two-fold.

1) # of visitors finding you via the SE's.
2) Conversion rate.

Both are very important factors.

This is anecdotal evidence only, but I know of travel sites which ranked #6 for years in one of the most popular vacation cities in the country, and that #6 position didn't produce enough revenue during the entire two years to pay their hosting bill.

That depends on the quality of your title and description tags the first:the more title and description reflect the visitor expectations the better.
Besides that,the site make the rest of the work:

It's thrue that the visitor pays his attention primarily on the first positins in the SERP.

However,I can have ranked in #1 position a bad site that doesn't produce any conversion even if visited thousand times per day and ,on the contrary,just have a #6 position ranked well made site that allows to me the best gain!

Let me say that personally I received conversion even from the third page of the SERP (24th position)...

Would it be possible that PPC ads convert better than organic listings on sites where action or transaction is required? This is totally suppostion and I would be grateful to here from anyone taht has any data on this.
