I had a problem with my previous Google AdSense account, consequently I had to create another one.
But when create this new one, setting up the same AD units and publishing it on the same website pages, I noticed the page CTR dropping to half the previous values. Consequently the earnings are much slower than before.
Details: The previous account was in US$ registered with an Brazilian address, and the new one is in GBŁ with an adress and bank in England, where I live at the moment.
The content of the site is in Portuguese. The ADs are showing fine, apparently, according to friends back home.
Before (one average month):
Page views 77,793
Estimated earnings $24.82
Now (last month):
Page vews 75,408
Estimated earnings UKŁ6.17
Does anyone have possible explanations?
