This is all a bit inspired by an article here:
and it has got me questioning if there is actually much difference these days between Google#1 and Google#5 when it comes to CTR (I think the data in the article says there isn't - even though the article argues that there is). I'm thinking of carrying out some larger scale research into it but don't want to re-invent the wheel.
So the most recent research I have found is here:
Comparison of Google clickthrough rates by position - Smart Insights Digital Marketing Advice
Which is pretty interesting in itself - especially how CTR for Google#1 varies so widely by industry. However I have a suspicion that they may have misused the data to arrive at their 'averages'.
But before I go and do anything does anyone know of any other recent research into SERP position and CTR? With Google changing the way it presents SERPS any research has to be recent to be relevant...
