The frequency capping option will limit the exposure of a Campaign/Banner. You have the option of limiting the amount of views per user within a specified time frame or within a browser session.
To specify a time frame select the “Total” option, then specify the amount of views and the time period. For example, you can limit a Campaign/Banner to deliver a maximum of 5 views per user, per 24 hours. If you would like the cap to last the duration of the user’s browser session, select the “Session” option. A browser session ends when a user closes their browser.
Frequency caps are achieved using cookies, Switch can only identify users who accept cookies. If the "Deliver to Cookieless Users” box is ticked, all users who do not accept cookies will be eligible for the capped Campaigns/Banners, but the frequency capping will not apply for those users. The capping of course still applies to those users who are accepting cookies and are therefore identifiable. When this option is not ticked, any users who are not accepting cookies will not be eligible for the Campaign/Banner and will be served a different Campaign/Banner.
Frequency capping can be applied at Campaign and/or Banner level. Caps applied at the Campaign level are spread across all Banners within that Campaign. For example, if a cap of 3 impressions per user per session is applied to a Campaign with four Banners, then each user will never see every Banner in that Campaign in one session. Applying a frequency cap to a Banner applies only to the selected Banner.
In cases where caps are applied to both the Campaign and the Banner the stricter setting will overrule the other. For example if a Campaign has two Banners and the Campaign is capped at 2 per user, per 24 hours but each Banner is capped at 3 per user, per 24 hours, the Campaign setting will overrule the Banner setting, each Banner will only deliver once or one of the Banners will deliver twice dependent on the eligibility of each Banner and the traffic on the ad units they are linked to.
