Question: Understanding SupportDeals(PBS), PreferDeals (PBS), SupportDeals (PBS), dealPrioritization (PBJS), prioritizeDeals(PBJS)

[ShriprasadM]

@bretg / @SyntaxNode / PrebidTeam , can you confirm if following understanding is correct?

Use Case	Should pass following params and configs in PBS go	Should pass following params and configs PB JS	Should use following keys in Ad Server Targeting
Deal Prioritisation for Long Form Video (LFV)	#1174	https://docs.prebid.org/dev-docs/modules/adpod.html#cpm-adjustments-by-deal-tier-for-csai	hb_pb_cat_dur https://docs.prebid.org/prebid-video/video-long-form.html#deal-support
Prefer Deals - In Prebid Auction only	ext.prebid.targeting.preferdeals: true #1355 #1528	dealPrioritization: true https://docs.prebid.org/dev-docs/publisher-api-reference/setConfig.html	hb_deal https://docs.prebid.org/adops/deals.html#deal-key-value-pairs
For LFV - To Prefer and prioritise deals	support deals = true, preferdeals = true	priortizedeals:true, dealPrioritization:true	hb_pb_cat_dur
Prefer Non-LFV Prefer and prioritise deals	preferdeals = true	dealPrioritization:true	. hb_deal

I can confirm the behavior of

• PBS ext.prebid.targeting.preferdeals: if true, this causes PBS to let deals win over non-deals when choosing the winning bid, which is the one that populates hb_pb, hb_size, etc
• PBJS dealPrioritization: basically the same as PBS ext.prebid.targeting.preferdeals

Unfortunately I cannot comment on the history of long-form video deal support. Will ask @SyntaxNode to weigh in on that. I would like to hope that we can obsolete any special support there for deals as we migrate LFV functionality into the main auction endpoint.

Thanks @bretg for an update. @SyntaxNode can you update on LFV part?

Another Question: What is the way one can prioritise the deals for non-lfv (banner, native) using existing flags, in both the cases server side and JS side? @bretg / @SyntaxNode

What is the way one can prioritise the deals for non-lfv (banner, native) using existing flags, in both the cases server side and JS side?

There's not a silver bullet here.

1. PBJS - https://docs.prebid.org/dev-docs/publisher-api-reference/setConfig.html#configure-send-bids-control

pbjs.setConfig({
  sendBidsControl: {
    dealPrioritization: true
  }
});

2. PBS invoked from Prebid.js

pbjs.setConfig({
  s2sConfig: {
     ...
     extPrebid: {
         targeting: {
             preferdeals: true
         }
     }
  }
});

It wouldn't be impossible to have the PBS bid adapter add this logic when sendBidsControl. dealPrioritization is set.

3. PBS invoked from SDK

host company needs to add ext.prebid.targeting. preferdeals: true to the 'top-level' stored request

4. PBS invoked from AMP

host company needs to add ext.prebid.targeting. preferdeals: true in the AMP stored request

Thanks @bretg.

1. Which targeting key, should be used to prioritise deals on GAM side in case of non-lfv format?

[bretg]

Which targeting key, should be used to prioritise deals on GAM side in case of non-lfv format?

Not following the question @ShriprasadM .

Prebid.js sends the hb_deal (or hb_deal_BIDDER) key-value pair to GAM. That's it.

Prioritizing in GAM is in how you set up the line items. https://docs.prebid.org/adops/deals.html

What's left on this issue @ShriprasadM ?

[bretg]

Are we good here @ShriprasadM ?

Deal support on the /video endpoint is a separate thing, not related to deal support on the main /auction endpoint. The /video endpoint is deprecated.

[ShriprasadM]

Yes @bretg . Thanks.
