How much better is a number one organic listing than a number two result? That is often a question webmasters, publishers, site owners ask themselves and others. A WebmasterWorld thread asked that exact question.
Tedster, a WebmasterWorld administrator, answered it with AOL's leaked data from 2006. Tedster shared the click-through rate by position:
- #1 - 47% click-through
- #2 - 13% click-through
- #3 - 9%click-through
- #4 - 7% click-through
The SEO Black Hat blog went through this in more detail. And so did the SEO Scientist. So take a look there as well.
I should add that Universal Search and the way the search engines are showing more than just organic results on a page may significantly impact these numbers.

People need to take that data with a heavy bag of salt. It is very old (more than 3-1/2 years). It represents a statistically insignificant subset of the Internet population (which numbered in the hundreds of millions at the time). And it represents only a fraction of just one search engine's audience. And it only captures 3 months' activity, thus failing to include full seasonal and cyclical trends. A lot of really bad analysis has been published on the basis of this data.

I don't care how bad the analysis is. No one is claiming it's exact numbers. It's simply meant to show the extreme difference between positions.

Why is this breaking SEO news? The data is nearly 4 years old and I don't seen anything new that's been added to the discussion. Just because it's the holidays, folks, doesn't mean you should recycle old news.

Scott, please read what I wrote above before being nasty. "answered it with AOL's leaked data from 2006" plus I linked to a post that is years old. I never said this was "breaking SEO news."

For a couple of my 'trophy' keywords/phrases, I have position 1 on Google with one-line sitelinks and Webmaster Tools reports a 26% CTR. Make of that what you will.

People tend to click the first listings in the search result, because they think that this will be the more appropriate and best result.
