You can choose how often vignette ads are shown to your users. Vignette frequency lets you control how much time must elapse before users are eligible to be shown another vignette.
Vignettes are shown when a user leaves a page or comes back to it. If the frequency setting since the last vignette was shown to a user has passed, the user is shown another vignette. By adjusting the frequency you control how often users might see a vignette on your site.
The default vignette frequency is set to 10 minutes. You can choose your own frequency from 1 minute to 1 hour depending on how many vignettes you want to show your users. For example, if you’re looking to earn as much as possible from vignettes, you might select the lowest frequency setting (1 minute). Alternatively, if you'd like users to see less ads, you might set the frequency setting higher (e.g., 10 minutes or more).
