Ad Serving for VAST #32

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
There should not be a separate mechanism for retrieving VAST markup.  The 
auction conversation between exchange and bidder should not vary by ad unit.  
I’m not sure if the intent is to call both the win notice and then the VAST 
URL or just the VAST URL, but either way the VAST URL should be eliminated and 
returned on the win notice URL; in the case of a VAST video, this is 
essentially the served ad markup.  The seller and/or SSP are quite capable of 
detecting whether the response markup is XHTML or VAST XML and will be 
expecting to make that determination based on the fact that it allowed VAST 
video in the bid request.

To amplify the point, when serving the ad in the bid itself (Section 4.4.1), 
the spec allows the VAST XML to be returned in the “adm” parameter just 
like XHTML.  The seller and/or SSP will have to make exactly the same 
determination in that case.  There is no reason for the win notice URL to be 
any different.
