After the CPM earthquake and the generic drop of earnings I'm seeing for my website, I read some people recommending to increase the number of ads.
I'm trying to find an optimal Impressions/PageViews ratio. Currently, mine is around 3-4 for not too short pages, with 8-15 paragraphs and maps. I insert 5 ads manually into the code (one above the folder and the rest scattered around the page), and I've set the 'auto load' to around 75% for 'in-page' formats. It seems that not all of them are actually showed.
Any feedback/tip is welcome.
My stats:
In the last 7 days, 95% CPM vs 5% CPC. In the last three years, 17% CPM vs 83% CPC
My earnings are dropping in February 25% Y/Y
My CTR has been 5-6% in the last years, and remains constant in the last days. Is it high or low?
