Bidder Price & Latency Analysis

While implementing Prebid.js’ adaptors for different bidders, we’ve noticed not all bidders return exact price to the publisher’s page. Different bidders also have vastly different response latency. We hope the analysis here can help you make smart decisions when implementing header bidding.

Bidder Price *Latency (rough estimate)
AOL Unknown Unknown
AppNexus Exact 200ms, however async calls have to be made for multiple slots
Casale Exact Unknown
OpenX Exact 500ms
Pubmatic Exact 400ms
Rubicon Exact 400ms
Sonobi Exact Unknown
YieldBot Exact 300ms

*Note that the above latency estimate was done in New York, US with fast Internet connection. To provide more accurate report, publishers can implement latency trackers through Prebid.js Analytics.
