Issues with Multi-Format requests to AppNexus

[generic10one]

Type of issue

Bug

Description

Using mediaTypes native+banner literally always responds with a banner ad. If I switch to native only, I instantly get native ads (with rates > than the banner ads). It seems like the only way to get native and banner demand to compete on a given ad unit is to use the same ad unit code twice with two different mediaTypes. I'm either missing something very simple or there is a problem with multi-format requests to AppNexus.

Steps to reproduce

Set an adUnit with both native and banner mediatypes. (with AppNexus as a bidder)

Test page

Multi-Format test page -> only banner ads

Same ad unit code twice with 2 different media types -> both native and banner ads are displayed

i've got a similar problem to this but i'm one iteration on, as in I have banner & video working but when I add native, I only ever get banner or video in a multi format unit
@generic10one did you find a fix?

@generic10one Sorry about the delay here; I was taking a look at your first test page and I don't see anything inherently wrong about the setup that should prevent the multi-format request from working.

There are some factors to consider though:

• what are CPM values associated to the banner and native creatives you're testing? Are they both using the same value or differing values?
• for the native creative you have setup in appnexus, is the icon asset actually using the dimensions 50x50? The sizes field in the native image/icon fields needs to be an exact match to the uploaded asset's dimensions, otherwise the appnexus adserver won't think that creative is a valid match.

Additionally, are your test placements/creatives still active? I tried both pages, but I'm not seeing any appnexus bids return.

When I made a copy of your test pages and swapped to a test placement we have setup - I was seeing some bids return, which made me think something happened to the original placements/creatives.

@jsnellbaker
Sorry for the delay as well.
The test order in DFP was paused for a while, now it is active again.

I don't think the icon asset is the issue here, since native ads are being displayed on the second test page

---

So, the issue remains -

1. Using mediatypes (native+banner) -> bids for banner ads only.

---

2. Same ad unit code twice with mediatypes for native only -> bids for both native and banner ads.

@spormeon

Did you try separating the different media types?

@generic10one
no i haven't yet as i'm using multi format units, one thing i have noticed though, is if i just have native and outstream, i get lots of native bids on good cpm 1-8 range, as soon as i add the banner mediaType back in, the bids all pretty much go to banner and on alot less cpm 0.10-0.50 range, so there seems something funny going on somewhere?
my multi format setup:
code: 'inreedvid4Slot',
mediaTypes: {
banner: { sizes: [[300, 250],[728, 90],[250, 250],[468, 60],[320, 50],[320, 100],[336, 280],[580, 400],[550, 310],[1, 1]] },
native: { image: { sizes: [300, 100], sendId: true }, title: { len: 50, sendId: true }, sponsoredBy: { required: true, sendId: true }, clickUrl: { required: true, sendId: true } },
video: { context: 'outstream', playerSize: [[550, 310]], mimes: ['video/x-flv', 'video/mp4', 'application/x-shockwave-flash', 'application/javascript', 'video/webm'], playbackmethod: [2], minduration: 0, maxduration: 45, protocols: [1,2,3,4,5,6,7,8,9,10], linearity: 1, api: [1,2,3,4,5,6] }
},
renderer: {
url: 'http://cdn.adnxs.com/renderer/video/ANOutstreamVideo.js',
render: function (bid) {
ANOutstreamVideo.renderAd({
targetId: bid.adUnitCode,
adResponse: bid.adResponse,
});
}
},
renderer: { options: { adText: 'Advertisement' } },
bids: [

can confirm i see that behaviour now, split the bids to banner & outstream, native on own and it bids for all, the offset of that is that nows endId: true doesn't seem to be being obeyed, where as it was when native, banner & outstream all in 1 multi format.:

@spormeon

I had the same issue with sendID - moving mediatypes:native above my banner bidders fixed it.

[spormeon]

@generic10one
again confirm, native first order, banner and outstream and sendid works again. offset again then though, is if you have more than one native bidder, you need to add, as without, it puts all the bids strings of url, image etc in the targeting: ( its all a bit of a mess really)

adyjs.bidderSettings = {
standard: {
adserverTargeting: [
{ key: "hb_bidder", val: function(bidResponse) { return bidResponse.bidderCode; } },
{ key: "hb_adid", val: function(bidResponse) { return bidResponse.adId; } },
{ key: "hb_pb", val: function(bidResponse) { return bidResponse.pbMg; } },
{ key: 'hb_size', val: function (bidResponse) { return bidResponse.size; } },
{ key: 'hb_source', val: function (bidResponse) { return bidResponse.source; } },
{ key: 'hb_deal', val: function (bidResponse) { return bidResponse.deal; } },
{ key: 'hb_format', val: function (bidResponse) { return bidResponse.mediaType; } },
{ key: 'hb_native_linkurl', val: function (bidResponse) { return bidResponse.native.clickUrl; } },
{ key: 'hb_native_image', val: function (bidResponse) { return bidResponse.native.image; } },
{ key: 'hb_native_brand', val: function (bidResponse) { return bidResponse.native.brand; } },
{ key: 'hb_native_title', val: function (bidResponse) { return bidResponse.native.title; } }
]
},

another offset, this method breaks S2S bidding with:
Invalid request: request.imp[0].id and request.imp[1].id are both "inreedvid4Slot". Imp IDs must be unique.

@generic10one Just to update, I'm still investigating into this behavior. I was having some trouble initially getting ads to return from appnexus while on my work network, but at home I am getting them near consistently.

I am seeing the reported behavior with the multiformat test page you created originally and the consistent delivery of the banner and native bids when you had them split apart.

It's strange that it's acting like this, as I have another test page based off of this page (http://prebid.org/examples/multi_format_example.html) that's properly rotating between the media types in the same ad slot.

It's possible this behavior might be due to something in the ad server setup (if only because the other example seems to be working), but I'm not 100% clear on that. I'm trying to reach out to some colleagues to check on this factor. I'll follow-up as soon as I can.

In regards to some of the other issues(?) that were discussed in the meantime between you and @spormeon - could you clarify a bit if you're seeing something wrong with the sendId flag in native requests?

Additionally @spormeon the setup you tried to use with S2S - is that the setup where you have two adUnits sharing the same adUnitCode but using different mediaTypes? Or is it something else? In either case - could you provide a copy of the adUnit setup so I can review? You can use https://jsfiddle.net/ if you can't provide a hosted test page for us to share the prebid adUnit code.

As a minor helpful note - If you want to paste code in github comments you can use 3 back-ticks (```) above and below your code snippet to make a proper code block. This will preserve the code in the comment when you paste it (and ensure all of it will get included).
