I've been doing some reading about APT and couple of questions have come up.
The first question stems from this quote:
If you want your third-party rich media ads to be shown on pages owned and operated by Yahoo!, you will need to make sure that you use one of the third-party vendors approved to serve ads to these pages.
I see a lot of companies that claim to be approved "rich media vendors", but I doubt they have all been officially approved by Yahoo, as the list that Yahoo gives is quite small.
Question #1: Are there two (or more) types of certification here? It seems like there are certifications for:
Third-party Vendor - hosts content outside of APT, but serving to Yahoo pages
Rich Media Vendor - creates standalone ads that are approved by Yahoo, e.g., meet filesize/compatibility requirements, but the ads are actually uploaded to APT and served by Yahoo so the hosting requirements are not a factor
Question #2: If I want to host my ads externally, but cannot meet Yahoo's "third party" hosting requirements (five nines, high requests per second), can I still be a certified third-party vendor, but not serve ads on Yahoo owned pages?
