what's page CTR?? so far I have between 1.3% and 2.5% CTR, is this ok? what sort of CTR do have to drop to to get smart priced? Thanks for your answers,
CTR stands for click through ratio so if you have 100 page views and you get 5 ad clicks then your CTR would be 5%. Smart pricing is not something I have experienced personally but as far as I understand, it doesn't revolve around your CTR but is based on the quality of the clicks you actually send. For ( a slightly extreme) example, if you send 5000 clicks and there are very low conversion rates for the advertisers then you could finish up getting smart priced fro something like that.
