CPM (Cost per Thousand) The most basic tool is CPM, cost per thousand of impressions, or how much it costs to have an ad published a thousand times on the Internet, and seen by users. CPM = what you pay to have your ad appear a thousand times CPC (Cost per Click) This is currently the most common tool; the product owner pays the website or host every time someone clicks on an advertisement banner. The cost per click is defined according to keywords and success rate. A keyword is used for a search; its rate is assessed according to its success. For example, the keyword «real estate» will be more expensive than «opossum.» CPC = what you pay to get a click on your ad So, if your CTR is low it means you are getting the traffic but less amount of users are clicking on ur ads, And if your CPM is hight it means the advertiser is paying you this much for that particular click..
in any case, low numbers are signs that your're not getting enough traffic, so there's a relation between the stats and it's the traffic.
