I recently redesigned my site and have experienced a 50% drop in income, though the CTR was reduced by only 10% and overall impressions are up 30%. I can't find any glaring reason for the drop. I switched from primarily table-based to css coding. The text on the pages remains almost completetly unchanged, except I took out some personal pages that never made any money.
Can anyone suggest any reasons for this? It happened the day I switched to the redesigned site, 2 weeks ago.
