Mobile content services ads are restricted. We allow the advertisement of mobile content services only upon certain conditions noted below. Mobile content services include, but are not limited to, sites that promote downloading ringtones, wallpaper, or text messages for predictions, love life advice, news, personality quizzes, or other entertainment services. We allow the advertisement of mobile content services only when the promoted website clearly and accurately displays the pricing. If your site promotes mobile content services and requires users to submit personal information, your site must prominently display the price and billing interval (such as per week or once per month) on the page where users first enter personal information (such as a name or phone number). If users sign up to your service by transmitting a code by text message, the price and billing interval must be clearly and prominently displayed beside the code. If your service is a subscription, you must provide a prominent opt-in checkbox or other clear mechanism indicating that the user knowingly accepts the price and subscription service. This should be on the first page users enter personal data, and the user should not be able to proceed without opting in. All of the items above should be located in a prominent place on your webpage and should be easy to find, read, and understand.
