The promise of header bidding: Opening up premium inventory to programmatic channels

This article was originally published in Venture Beat on November 29th, 2016. I have written previously about the conundrum of header bidding. While my thoughts back then are still valid, the technology has progressed and the market is following. Following this, I’ve posted the good, bad and ugly of header bidding.

Everyone is talking about the promise of header bidding, but what does it really mean to the future of publishing and mobile monetization? Header bidding is leveling the playing field by allowing sellers to make more intelligent inventory allocation decisions between traditional and programmatic demand. For advertisers, it allows for better campaign delivery and optimization by providing more access to audiences at scale.

By implementing header bidding, publishers and app developers are able to expose every single impression to a programmatic marketplace. Many sellers are already reporting 40-50-percent increases in CPMs, and buyers have a new ability to bring their data to bear across multiple inventory sources.

Page Performance and Ad Tech: Speed is still a feature on the open web

Maintaining a good user experience while delivering quality content, and paying for it

Page Performance - A cautionary tale

Page performance has been cited as a reason to install an ad-blocker. In fact, a recent straw poll suggests that 71% of ad-blocker users would whitelist a publisher website if the page performance didn’t suffer. Blocking ads, which can be half of the content of a web page, will almost certainly improve the page performance. Mozilla Firefox even has a “reader view” available for many pages that removes all the content except the main body copy. That feature goes as far beyond ad blocking as you can get.

The four things that slow down page performance are:

  • the number of requests the browser is making
  • the time it takes for a response
  • the payload associated with each request
  • the code executed on the page once the request is fulfilled

In many cases the executed code will make additional requests and the dance starts all over again. This process takes a toll on page performance and each browser responds a little differently to the tasks. The browser may appear sluggish or unresponsive while the page elements are loading, executing or rendering. It may present the loading icon in the tab, which itself can freeze.

Floors In RTB: Are hard and soft reserve prices known to the DSP?

I assumed that before bidding, DSPs could not be sure whether an SSP applies floor price rules to an auction. Now, I saw some remarks in the academic literature implying that buyers know about the existence or even the exact quantity of floor prices.

In practice, do SSPs communicate their floors?

This question was asked on quora, below is my answer.

Floor Prices in an AuctionThe answer is: sometimes. Exchanges sometimes express floor or bid guidance in the bid request. This is not required for the market to operate; so many exchanges do not provide any guidance. Floors are almost always in play. In most cases they are dependent on a wide variety of variables including: the site, browser, device, day of week, time of day, audience data, user’s language, and geographic location of the user.

Auction Mechanics

Floor prices, from an academic standpoint, are there to protect the base value the publisher has placed on the inventory. Bids falling below the floor, or reserve, are usually rejected by the exchange. Losing bid information might be recorded to give the publisher insight on the value advertisers are placing on the inventory and accompanying traffic. Next: Price Floor Discovery

Disrupting the Bid in the RTB Auction

RTB Bid Keys

Your eyeballs are on the block, but they don’t always go to the highest bidder.

“In RTB, will the bid with the highest CPM always win? If not, what are the other factors?”

This question was asked on quora, below is my answer.

In a pure auction, the highest bid should always win. In many cases an RTB auction ends with this result, but not always. There are two or three things that will adjust the auction mechanics to give a lower bidder the impression. Most of the time a modified auction is at the behest of the publisher. Read more
