Interesting. Google Webmaster Tools now shows click though rate and position in SERPS.
I picked a term I know I have had the top 5 positions at various times, and it’s interesting to see the clickthrough rate on particular keyword searches…. and how many clicks the top position in Google gets compared to the number 3 position, no4 and no5.
Obviously, this is just one example – it will take a while to look into the new data and look at an average – but it shows a number 1 getting nearly 30% more of the clicks than a no2 ranking. You might find some useful nuggets of information at Google Webmaster Tools for your own site…..
Of course, click through rate can be skewed by any number of factors – the nature of the query or how compelling your call to actions are in your title and your meta description, to name just a couple.
This info might prove interesting once aggregated.
EDIT – There’s plenty of discussion on the web about this data now – and how it doesn’t quite tally up with other Google sources (surprise suprise) and some even claim this info might have been published by mistake lol
