This app allows you to place limits on the number and type of ads that are shown on a landing page or user session based on referral source simply by creating a 'rule'.

Rules will allow different ad combinations to be shown, either on the landing page or across the whole user session, i.e. on subsequent pages. The App tracks the traffic referral source applies the rules you create and restricts the number and type of ads accordingly.

So, for example, if you are running a campaign on Facebook, you can generate a rule based on your Facebook campaign UTM. In this case, the ads will be restricted for traffic arriving at the page from Facebook, but will not restrict ads to users arriving from other social, organic or direct traffic sources.
