Payout Dropped by half!

Smart pricing affects the whole account.

 

It may depend on various factors..
like, google's change of clickable area, dropped CTR, dropped CPC, dropped traffic etc..

 

I agree with seo4china - don't forget that over time, advertisers are getting smarter too! For example, you're not being 'site targeted' are you?

 

Adsense implemented the click on title for the ads, no more in the box misclick. that bound to bring down earnings in short term.

 

I saw the same, my earnings for november dropped a lot.. must be the clickable area change

 

here's one interesting post.
