Frequently Asked Questions
Take a look at some of the most common questions and answers we get regarding Bidder Adapter.
Why isn’t Project Agora Bidder Adapter on prebid.org?
Bidder Adapter technology has been built using the Appnexus Server-Side technology. That’s why the first step of the implementation is to include Appnexus as a bidder adapter in the prebid library.
Therefore, Project Agora Bidder Adapter is not necessary to be directly listed on prebid.org.
Does Bidder Adapter affect the sites or ads loading time and viewability?
The delay added is the same as adding a new demand source (bidder) in your header bidding solution, which does not mainly affect the page content load time or the ads load time.
More specifically, the latency added when adding a bidder is marginal (on average 50-100 ms).
Due to the low latency tax added, viewability is also not affected.
Am I able to exclude any of the SSPs that are integrated in Bidder Adapter?
Even if you are having SSPs overlapping with the ones we utilize for Bidder Adapter there is no need to exclude any of them. The total overhead added by our bidder is minimal (50-100ms) and is not affected by the number of SSPs connected on our side.
Additionally, due to our volumes and our global presence, we are able to get better terms than the average publisher and also negotiate deals with advertisers across our inventory. Thus, even if the Demand Sources are the same, the demand is not. Also, Bidder Adapter’s bidding is “Net”, which means that it bids in real time the exact amount publishers will make from each auction.
At the same time, our team of Yield Optimization Experts maximizes the value of every impression by selecting the optimum combination of these Demand Sources, tailor-made per Ad Unit, device, geolocation, etc. In case the performance of the overlapping Demand Sources is poor, our team will identify it and remove them.
Lastly, you are able to exclude/block specific ads from appearing on your pages (by entering a top-level domain) via our Partner Center.
Should we update the configuration in every new build of prebid version?
No additional changes are needed every time you build a new prebid version. More specifically, you only need to ensure that:
- Appnexus bidder is included in the prebid library
- The code added in the site’s header bidding configuration with regards to Bidder Adapter has not been affected
