Hi all,
Long time lurker, first time poster here...
Firstly let me preface this by saying I've watched the "ad auction" and "smart-pricing" videos on the AdSense YouTube channel. From what I understand smart pricing applies to an account as a whole and traffic from a single underperforming (poorly converting) site can drag down the CPC for your whole account.
My question is, have any of you who use analytics in conjunction with AdSense ever noticed a significant difference in the CPC you get from clicks from different traffic sources? For example, in my experience social media traffic typically yields a lower CTR, but does that also translate to lower CPC in the form of smart pricing? Is there any evidence to suggest that smart pricing is that granular in action? Although I have recently hooked my analytics account up to my AdSense account I don't yet have enough sample data to draw meaningful conclusions.
Any insight would be welcome (and interesting)...
Regards,
James
