SERP Click Through Percentages
In August 2006, AOL fucked up massively, they released click through data of their Search Engine users. Well, not all of them just 20 million web queries from 650,000 AOL users made over the course of three months. You can get the torrent on Mininova if you want a look: http://www.mininova.org/tor/388815
There were pretty much no surprises. People search for shit, they don’t conceive anything they type might be stored or that they are tracked as an individually identifiable user so they drop their guard. ho hum.
Anyway, the interesting thing to know is that AOL search is a white label of Google. AOL add a shitload of crud to the SERP which makes it ugly and the algorithm used is a bit ‘safer’ than the live Google algorithm but generally, AOL Search is Google.
Because the SERP click through metrics were released we can work out which ranking gets which traffic, this is really useful. It’s improbable that Google would ever release this kind of information. AOL shouldn’t have done and people got sacked for doing it… but hey, their loss.
So we can see that the first ranking on a SERP, according to the harvested dataset gets clicked on by 42.3% of the people who see it, second place gets 11.92% etc.
Some things to know and think about:
- Who’s clicking on the PPC Adverts? Anyone?
- AOL SERPs pages are maxo pimpo compared go Google, the fold is in a completely different place
- Other stuff I can’t be bothered to type
