This is a tool for people who buy and/or sell online traffic. Everything should be self-explanatory, but in case you're new to it, here are a few pointers. CPC (cost per click) and CPM (cost per mille – 1000 views) are the two most common models of billing for internet advertising. With CPM advertisers pay based on how often their ad is shown to users.
For example, when you buy 10,000 visits with a $2 CPM, you'd end up paying $20 for the whole campaign. With CPC advertising, advertisers pay for actual visits to their site. For example, you may agree on $1.5 CPC and this is how much you'll pay for every single click. Once the campaign airs and you see how your ads perform, you can easily calculate CPM from CPC and CPC from CPM via another metric called CTR (click-through rate), which simply means "how often do people click on my ads".
If you're on the buyer's side and would like to calculate everything that goes into the process (from impressions, through clicks/visits, leads to actual sales), try our online marketing conversion calculator. Also, we have a simple CPM calculator if actual visits aren't your concern.
