I'm looking for facts and figures (if any) related to click throughs and positioning on page 1 of Google to present to an offline client. I've been looking on here and other sites but can't find anything useful.
They are currently ranking on page one for a number of long tail terms. For some they are are position 1-3, others they are at the bottom of page 1.
They obviously know that being page 1 position 1 is better than being at the bottom of page 1, but want to know if it's worth investing in more offline work to get higher on page 1.
Are there any studies on this sort of thing? I know there are plenty of facts knocking around about how many people view results on page 2 or beyond but wondered if there is anything similar for page 1 results.
