My site had authority ranking for more than two years now and I lost the rankings (sitewide), 2-10 places down on 19th January 2012.
My site has a blog layout, 70px header, main content (650px) on the left and two sidebars on the right. I had 336 unit (above the fold) in main content area, float to the right side. And in one sidebar, two 160 units.
Is that a lot of advertisement?
I now replaced 336 unit with a 300 one, and on many inner pages removed the 336 block. Google hasn't crawled my site since the changes were made. Should I be removing more ads, I already see a decline in CTR.
Also, does Google penalize specific pages or the whole site?
