If...
If each advertiser's media is in a scene.
And in every scene that has:
- The ads file.
- A component SWF or HTML hidden.
The URL that will load the component will be the ID of the ad, and in accordance with this ID, loads the Google Analytics.
That way you'll know the exact time that the media was shown. And also know in real time. And also how many times it was shown.
As example:
www.yourwebsite.com/analytics.php?ads=1And in its database, the ads number 1, you show the correct Google Analytics a Code in accordance with this ID.
It is one of the best solutions. Because you have control over all ads in real time.
Thanks! =)
