Many newcomers to online ad buying have questions regarding the traffic they can buy through a demand-side platform (DSP). How much does it cost? How much of it is available? What is the quality like? The answers are actually interrelated, and require an understanding of the mechanics behind how real-time bidding (RTB) works. Industry Terminology Explained First, a clarification of some industry terminology. The first page that a visitor views — more often than not the home page — is called the “first impression.” The second page is the “second impression,” and so on. Since most advertisers covet lower session depth (session depth refers to the number of pages viewed by a visitor in a particular viewing session, with lower depth corresponding to earlier views), publishers will often sell these impressions in bulk through direct deals with advertisers. Impressions that are not sold through direct deals (usually those with a higher session depth) are … [Read more...] about The Mechanics of Real-Time Bidding

Update (2008-4-13) – It’s nice when an old post gets pointed to because of recent changes and developments. The official Google Webmaster Central Blog has a new post co-written by Jayant Madhavan and Alon Halevy about technology that they’ve “recently been experimenting with,” in Crawling through HTML forms. It looks like the promise of Transformic’s technology is living on at Google. Anand Rajaraman, a friend and co-author and former intern to Alon Halevy, provides more details about this development from Google in his Datawocky post, The story behind Google’s crawler upgrade. Google Operating System adds some additional thoughts in Google Starts to Index the Invisible Web… ***** Reading a Washington Post article, Google Goes to Market, I noticed a company name in a list of Google acquisitions made that I didn’t recognize, and hadn’t included in my list of Google Acquisitions. The company is Transformic, Inc., which ran … [Read more...] about Google’s Quiet Acquisition of Transformic, Inc.
I’m having a bad day. Aside from my desktop crashing, we get another spate of“let’s blame SEO” to start my morning off. Robert Scoble uses that theme asa launching pad for aseries of videos on how Facebook potentially could bea killer search engine — regardless of the fact he seems to have no cluethat “social graph” or social networking mixing has been tried and abandonedwith search. Having watched his videos, which have sparkedmuch discussion,I’ll do some debunking, some educating for those who want more history ofwhat’s been done in the area, plus I’ll swing around to that New York Timesarticle today that ascribes super-ranking powers to SEO. Robert’s excited about “social graph search,” which is the idea that ifyou know a network of people, you can use their connection to improve searchresults. It’s a “revolution” coming in search that will overtake all themajor search engines, he says. … [Read more...] about The Promise & Reality Of Mixing The Social Graph With Search Engines
As expected, the US Department Of Justice today has filed a list of objections and modifications it would like seen made in the proposed settlement to the Google Book Search lawsuit. It’s not saying that the settlement should go back to square one. In fact, it suggests that “momentum” potentially could be lost to improve access to books if that happened. But it does want the settlement modified, in particular to protect absent rights holders of “orphan works” and to solve anti-trust concerns. You’ll find a copy here (PDF) at the Public Index. The New York Times has a summary up here. Gary Price has a press round-up here. A Google statement is at the end of this article, along with one from the Open Content Alliance, which opposes the settlement. As for the article itself, I’m reading through the entire filing from top to bottom, pulling out parts that seem worth highlighting and providing my own commentary along the way. I’m not a lawyer, … [Read more...] about Department Of Justice Files Objections To Google Book Search Settlement
Want to do a paywall with no “first click free?” That’s fine with Google, says business product manager Josh Cohen. Want to do micropayments? Google will be “flexible” in considering support of new business models like this. But if you charge, expect less traffic, and also expect that your competitors will be “ecstatic” to pick up your loss, he said. Cohen’s comments on paywall issues were part of a wide-ranging interview I had with him about Google and its news service. In the interview, Cohen also repeatedly stressed that publishers are free to deal with Google as they like. And if they wanted to exclude Google in favor of a competitor like Microsoft, they have that choice — though Google would prefer to work with everyone. Indeed, Google’s inclusion of many diverse sources is one reason he thinks Google might take hits from certain publishers that don’t criticize Yahoo News, which is a far more popular news service … [Read more...] about Josh Cohen Of Google News On Paywalls, Partnerships & Working With Publishers
