Example of current banner
We have customized the banner for the content in which the client advertised. We did not want to interrupt. Vice versa. We wanted to be part of the place where the banner was placed.
CPM (cost per 1000 impressions): $ 10.
Daily client budget of $ 200 (20,000 impressions daily).
CTR: 0.42 % (daily 84 clicks on banner).
CPC (cost of one click): $ 2.38.
The client's conversion rate from these banners was: 0.6 %.
That means that of 167 visits, 1 order was made.
Value of one conversion (client orders): $ 180.
For one order, we need 167 visits x $ 2.38 per click on the banner.
The cost per order is $ 397.
CPM (cost per 1000 impressions): $ 10.
Daily client budget of $ 200 (20,000 impressions daily).

For one order we need 167 visits x $ 0.55 per click on the banner.
