I am trying to optimize a list of websites on which to purchase banner advertising using the following setup:
For each banner ad impression I buy I am charged $0.001.
When my ad is clicked it results in $0.50 revenue.
- Each website has a constant but different number of visitors per day.
- You are only allowed to pick the top 10 sites for your campaign.
- You have a fixed budget on which to spend advertising
Initially I approached this problem simply by calculating ROI for each site. However, my budget was not being spent because the sites it chose did not get enough visitors.
What I really want to calculate for each website is a value of Profit Per Minute. How do I approach this?
Also, this should be a rolling time series as the set of data changes every second.
Thank you.
