Ad Blocking Benchmarks for Digital Publishers

Thanks to everyone who took the ad blocking survey last week! As promised, the results are posted below.

Ad Blocking Survey Design

There were 57 participants who took part in the survey over the course of ten days. I promoted the survey through various channels, including Twitter, LinkedIn, the Ad Ops subreddit, the AdMonsters forum, and naturally on this site. The survey itself was powered by SurveyMonkey. Here’s how it breaks down in terms of respondent referral source:

Because I also ran this survey as anonymous by design, I can’t make any statement about how many of these publishers are big, premium brands, and how many are smaller shops. That said, Ad Ops tends to be a community that serves larger publisher organizations so my expectation is that we’re looking at trends that reflect professional publisher organizations and not amateur shops.

Summary: Publishers Concerned, Ill-Prepared for Ad Blocking Impact

At best, the survey results show publishers are just starting to confront the issue of ad blocking; at worst, they show publishers as woefully unprepared and without much of a strategy.  Here are the highlights: (more…)

A History of Ad Tech Acquisitions

Updated: Nov 8, 2016

Today I’m publishing a list of over eight hundred ad technology acquisitions as a resource going forward. You can read more about the methodology on how I decide what to include and what not to include on that page, but I will be keeping it up to date moving forward, adding companies each week as transactions happen.

Pulling this list together was a ton of work, but now that I have it, we can do all kinds of interesting analysis on the trends we’ve seen over the past 15+ years.

Overall Trends

No surprises here, there’s been an explosion of acquisitions as the market has grown and capital has been cheap.  Entirely new sectors were created during this timeframe; remember – there was no such thing as mobile ad tech in 2000, no such thing as video ad tech in 2002, no such thing as social ad tech in 2004.

The First Ad Tech Acquisition – LinkExchange

So far as I can tell from my research, Microsoft’s $265 million dollar purchase of LinkExchange was the very first ad tech acquisition – nearly 17 years ago! LinkExchange was the very first ad network model and figured out how to monetize the then-popular concept of a web-ring. For all you whipper-snappers out there, a web-ring is a cooperative effort by many publishers to link to each others’ sites in hopes of driving traffic. Usually, they popped up in common niches, so people who had a site about robotics, or space travel, or nature photography, or the New York Yankees would all put links to other related sites. LinkExchange figured out how to build a business off that concept by allowing publishers to promote their own site across a huge web-ring in exchange for serving paid, promotional links from LinkExchange every so often.  This was good for publishers because it gave them greater exposure, and was good for LinkExchange because it enabled them to create a platform that could reach a very large percent of the internet for advertisers.

LinkExchange is also notable because it was founded by Tony Hsieh, who went on to future greatness as a thought-leader in office culture, and the founder of Zappos which he sold to Amazon ten years after LinkExchange.

Early Years (1998 – 2007)

The early years of ad tech acquisitions are not well documented, so frankly I feel less good about my data, but the dot-com bubble that collapsed in March of 2000 likely put a damper on any significant transactions.  One that just squeaked by though was the NetGravity purchase by DoubleClick for a massive $530 million in 1999.   (more…)

The Display LUMAScape Explained

Ah, the LUMAscape, who in the digital marketing world doesn’t know it as an old friend at this point?

Display LUMAScape

First debuted in 2010 by the ad tech banker Terry Kawaja, the LUMAscape has been through many iterations at this point, adding companies, changing categories and noting acquisitions over the years.  From the very beginning this image was a hit with the digital marketing set as it provided a way to understand a complex industry, as well as a symbol for how difficult it is to work in a space so complex!  The LUMAscape was a great way for ad technology people to explain the growing industry within their own companies in a visual way, as well as understand how new companies were aligned and fit together. Kawaja & team’s image was also a solid way to understand what a whole lot of companies even did, so if you were say, shopping for a data management platform, you could get a quick sense who the four or five companies in the space were.  For Kawaja’s company, LUMA Partners, the LUMAscape was also a great way to show the sheer amount of fragmentation in the industry and possibilities for consolidation through acquisitions, on which his company specializes in advising.

Whatever the motivations, the LUMAscape is an iconic image in the digital marketing industry, and a must-know resource that Kawaja’s company has generously kept up to date for nearly five years now.  But the graphic itself only tells a high-level story and can oversimplify, as the LUMA Partner’s website readily admits, so I thought it could be useful to take this image down one more level and explain some of the nuances and sub-categories within each service.  This article describes what each category coves, what a lot of the companies on the LUMAscape actually do, as well as the differences between key services within specific categories.  For those that are new to the industry, I hope this post not only demystifies this graphic, but gives you a well-rounded sense of how the digital marketing industry functions, and for industry veterans who already know the basics there’s probably still a few things to learn.

Header Bidding Explained Step-by-Step

I’ve gone over what header bidding is in an earlier post and some of the key differences versus traditional tag based setups, but I’ve always strived to technical bluntness on this site as well, hence the diagram and step-by-step path below.  As a point of comparison, it could be a good idea to re-familiarize yourself with how ad serving works and the standard exchange redirect path at this time as well.  Note that header bidding is also sometimes referred to as ‘advance bidding’, ‘tagless’, or ‘pre-bid’ integrations.


How Header Bidding Works

How Header Bidding Works:

  1. User requests a website
  2. Header tag script redirects user to one or many SSPs (or DSPs, or Exchanges)
  3. User calls one or many SSPs in parallel
  4. SSPs conduct auction with DSPs and internal network demand*
  5. DSPs respond with bids*
  6. SSP determines winning bid value and returns to User
  7. User passes bid value into ad request and calls Publisher Ad Server
  8. Ad server determines final line item to serve and redirects User to Marketer Ad Server (let’s assume the ad server determines a pre-bid SSP line item for this example)
  9. User calls Marketer Ad Server
  10. Marketer Ad Server returns final creative (via CDN)
  11. User calls trackback to SSP

* It’s hard to tell if everyone or no one actually runs an auction with their header tags because everything happens quite fast relative to your standard exchange process.  My sense is that there is either some kind of estimation process vs. a real auction, or some fancy stuff happening with the SSP’s CDN, but without the product people or engineers from these companies actually telling me what happens it’s impossible for me to know.  Here’s hoping a few visit the comments section on this article.  The important point is that the SSP determines a value for the impression that the publisher can use in their ad serving decision process. How precisely that happens and if it’s better / worse than the standard auction process is an open question. (more…)

Header Bidding: Holistic Ad Serving Is Here

It’s been nearly three years since I first wrote about the concept of holistic ad serving – the idea of seamless yield management across sales channels, namely direct sold and programmatic – but in the last six months or so this idea has quietly gone from the drawing board to reality via a mechanism known in the industry as ‘header bidding’, ‘tagless’, ‘advance bidding’ or ‘pre-bid’ integrations because they rely on a piece of JavaScript in the publisher’s header to work. Header bidding is a revolutionary enhancement to the way publishers have historically integrated with their SSP partners, and has wide ranging implications for nearly every part of the RTB ecosystem. The future is now!

Header bidding integrations, or something very close to it have been common for years with retargeting networks like Criteo seeking ‘first-look’ relationships with publishers, but it’s only recently that the major sell side platforms started to integrate this way. The major difference between the retargeters and SSPs is that retargeters have all the demand within their own platform, while the SSPs and Ad Exchanges rely on an auction with external parties to fill impressions.
