FAQs

What is an APID?

An Ad Placement Identifier (APID) is a placement id number given to you by Millennial Media. This unique identifier tells us which site is calling for ads, and allows us to keep track of your revenue and advertising statistics in the mMedia portal.

Where can I get an APID?

Visit mMedia.com to create an account, register your site, and recieve an APID.

Why is my site not showing any ads?

It takes some time to activate an APID in our system, so you may not see ads right away. If you are still not seeing ads after 2 hours, please contact us for more help.

Why is allowing location information to be passed on the placeAd call so important? Is it required?

Passing the location object is important because it allows us to deliver targeted and contextually relevant ads to your users. While it is not required, better targeting often results in higher conversions and higher eCPMs.
