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

Why I Built Scrypter

Buying the (Blueberry) Farm

One of the more interesting decisions I’ve made was buying into the blueberry farm. It came about “innocently” enough. My brother and father conspired to pitch an investment opportunity in the form of blueberries.

From Email to Farm

Blueberry FarmersIt was 2006 and I was reaping the benefits of the email business I started with a partner back in 2002. We, of course, starved and scrambled to find work for the first two years, but then something hit. One of our clients, a good friend from before the bubble burst, got us pointed at an email platform. We built it, and then managed to find another client who needed one. So we licensed it, and so began our email business.

By 2006 the business was humming along. We had several clients and were expanding into other opportunities. There was a substantial surplus of cash that we opted to take out of the business. This allowed me to pursue other ventures, like farming. Internet technology and farming go hand in hand, right? Read more

How is an RTB winner chosen in the case of identical bids?

When multiple advertisers are bidding for a certain (impression) and more than 1 enter the same bid amount, (each) being the highest, how does the RTB (auction) determine which ad should be displayed.
This question was asked on quora, below is my answer.

Identical BidsIdentical bids are not unheard of, but they are rare.  Bid prices are presented as a CPM value with up to five decimal places.  That means that the actual impression can bid upon with precision down to eight decimal places.  So in that rare event, when there are two or more matching top bids, the winner is chosen at random.  This is only the tip of the iceberg, though.

Features are being added to RTB systems that allow for preferential treatment of preferred DSPs, agencies, trading desks and even advertisers.   Deals that are struck between site owners and buyers are being executed through the RTB infrastructure.  Those deals can supersede standard auction mechanics, resulting in a winning ad from a preferred partner in the presence of matching (or higher) bids from other parties.

As time goes on and the RTB system is exploited for more and more features, having equal footing in an auction will be more rare, relatively speaking.  There will always be general auctions where no bids are given special consideration.  We are, however, entering an era where premium inventory is available to buyers through RTB.  With that inventory comes a more carefully crafted environment to buy and sell.
