Impression - An impression is generated when a banner, or text link, displays on a web site. This can be a good indicator as to how many times your Web page is visited and also gives you a good idea as to the amount of visitors it takes to generate a transaction through your links.
Click - Clicks are generated when a person visits your web site, and clicks through to the advertiser through one of your links. These appear on Performance Reports but not on Transaction Reports.
Lead - A lead is generated when a consumer goes to an advertiser’s web site and signs up with the program, fills out a form for more information, downloads freeware, etc. Essentially it captures consumer information in some way, but doesn't necessarily equate to a initial revenue-producing activity. If you are promoting an advertiser that offers commissions for the submission of any kind of lead, read the advertisers’s program terms and any other special terms and conditions very carefully. Submitting false or fraudulent leads is specifically prohibited by Commission Junction.
Sale - A sale is generated when a purchase is made from an advertiser.
CPM - Cost per thousand impressions. CPM is a metric for online advertising where a rate (cost) is set for every thousand impressions displayed.
CTR - Click-through rate. This is the percentage of clicks registered compared to the number of advertising impressions displayed. For example, if an ad appears 100 times and as a result 2 clicks were registered on it, then that ad would be said to have a 2 percent click-through rate.
CR - Conversion rate. This is the percentage of visitors who take a desired action on the advertiser's site. The action that determines conversion is decided by the advertiser and may be a sale on the advertiser’s web site, a completed lead form, or another action. Conversion Rate is calculated by dividing the number of resulting actions by the number of clicks registered in the same timeframe.
