Who sees your ad
Each creative can be limited to a language (the English or the Russian site) and to the registration country of the player. Without a limit it is shown to everyone. Players who are not signed in see only creatives with no country limit. When several creatives match, the one with the higher priority is shown.
Video ads repeat for the same player no more often than the interval set for that creative, in minutes. Banners and printed ads have no repeat limit.
Rules
- An ad must not look like a puzzle, a game control or a message from the site.
- Video ads play without sound, and the player is muted.
- Banners link to the advertiser's own site. Printed ads cannot be clicked, so put a web address or a code on them if you want people to find you.
- We do not run ads for gambling, adult content, or political campaigns.
- We check each file before it goes live and may refuse one that does not meet these rules.
