Google is enabling traffic laundering, where websites with pirated content redirect visitors to shell websites displaying AdSense ads. These ads finance piracy, and Google is taking a cut in the process. Google clients have no clue of the reputational risk they run by using AdSense.

May 11, 2016

Executive Summary

The automatization of ad placement happened at the expense of control and due diligence. This created a market for low quality traffic, dominated by traffic brokers. The new layer of intermediation in the system made fraud harder to detect.

A simple example of how an illegal streaming website monetizes its traffic through AdSense shows how Google is behind the curve in preventing fraud.

Google and the rest of the ad tech industry are putting their clients' reputation and brand image at risk, and directing ad budgets to shady and illegal websites.

The online advertising industrys expansioninto subprime ad space and automated ad placement has put themselves in an intenable position. Its time to differentiate between the good, the bad and the ugly.



The automatization of ad placement has created a market for low quality and fraudulent traffic, runbytraffic brokers

The rise of ad tech since the early 2010s, by enabling more and more websites tosell their ad space, has created a demand for traffic from these websites. Traffic brokers emerged (Chart 1), buying traffic that couldn't besold to ad tech or AdSense, and reselling it to... someone else. The idea was, if you buy traffic cheap enough, and resell it for more, you could make a living. The highest bidders,namely ad tech companies and AdSense, were at the end of the value chain.

By design, traffic brokers dealt with low quality traffic, because anything high quality could be sold to AdSense.Long story short, this meant bots and fraudulent traffic: people that were served popups, misleading links, inside frames, and the like (Chart 2).

The unintended consequence of traffic brokers was thatby spreading outgoing traffic amongmultiple websites, and not telling where a visitor came from,they made it much harder to detect fraud and bots. A website could send millions of bots through a traffic broker's network, and these would be dispatched through thousands of websites, mixed with a natural flow of humanvisitors, and turn into nothing more thannoise. Another website could attract visitors with illegal content, such as online moviestreaming, and resell them to other websites in the network, by hiding the original point of entry of this fraudulent traffic.

A real lifeexample of how an illegal website monetizes its traffic thanks to Google's AdSense, without even infringingGoogle's policies

In a September, 2013 document titled "How Google Fights Piracy", the company outlines its anti-piracy practices. A shorter version of the document has been posted by Fred von Hohmann (, director of Googles legal copyright team.

One of the three major points of the document is "Follow The Money". It states: "When it comes to rogue sites that specialize in online piracy, other anti-piracy strategies will have limited effect so long as there is money to be made by their operators. As a global leader in online advertising, Google is committed to rooting out and ejecting rogue sites from our advertising services, to ensure that they are not being misused to fund these sites."

In all appearances, Google is fighting piracy by removing infringing results from search, and by banning infringing websites from its AdSense program.

However, Google does littleagainst websites that receive traffic from infringing websites. Thus, it creates a market for traffic arbitrage, where infringing websites reselltraffic to intermediaries displaying AdSense ads., a website that aggregates links for illegal streaming of TV shows, is estimated to receive almost 100 million visits a month by SimilarWeb. Obviously, it couldn't useAdSense ads. However, at the bottom of every page it displays a banner of eight click-bait links to other websites, powered by a shady traffic broker, Nativly. When youclick on any of these links, Nativly pays a fewcents, and redirects you to another website, which it charges a little bit more than he pays (that's what traffic brokers do).

For instance, ifyou click on the first link with the "man nostalgic for the 1990s", the browser opens a new tab to a generic article on, and surprise! Its full of AdSenseads:

From time to time, visitorswill click on these AdSense ads, and willget paid by Google for the click. This "traffic arbitrage" worksas long as revenues generated from AdSense clicks are higher than the cost of attracting visitors through Nativly. is afake website. The profiles of its "contributing authors" are illustrated by stock photos, and its content isvague and useless. However, ithas passed Google's controls to become an affiliate of the AdSense network, in particular the "Low value content" rule of Google'sAbuse of the Ad Networkpolicy.

We ran an IP cross-check, and discovered that the server hosting also hosted, at some point in time, otherfake websites with identical layouts and HTML formatting,,,,,,,,,,,,,, All these domain names were registered through a proxy, Their owner obviously desired to remain anonymous.

The scheme for this traffic laundering, and ad money flow, is summarized below:

Follow the money indeed

Google has recently filled the Internet with its PR about how revolutionary its artificial intelligence is. Googles algorithms are now capable of beating humans at the game of Go. And yet, they apparently arent able to look into my browser history to realize that I came to a Google Network affiliate from a website specialized in piracy, through a traffic broker.

The Digital Citizens Alliance, a non-profit focused on Internet safety issues, estimated that websites specializing in pirated content raked in $227 million in ad revenue in 2013. That was three years ago, when automated ad placement and ad tech was only in its infancy. God only knows the extent of piracy ad fraud today.

Every intermediary is taking a cut in the process. In the end, Google AdSense is the go-to guy to monetize all this shady traffic. Ultimately, Googles clients pay for everything.

The worst part is that this whole scam is, technically, in accordance with Google's own policy. The ads are not served on websites with infringing content, and the shell website that hosts them has just enough content to pass the "low quality" test. Maybe that's why they have been running since July 2015,siphoning AdSense's clients ad budgets for the benefit of shady intermediaries and pirates.

Google and the rest of the ad tech industry are puttingtheirclients' reputation at risk, andhurting their brand image

Havoscope, a website specialized in market risk and security threats from the global black market, estimates that the larger piracy websites rake in over $4 million a year in revenue from advertising. They are the last link of the chain; Google AdSense must see much bigger amounts flowing through its system, and does nothing but taking a cut.

By placing ads on shady websites, Google isplaying with fire. We have researched this piece from Paris, France. When we were redirected (the shell website described above) from, wewere served by AdSense-powered ads for SFR, amajor French telecommunications company. Or this ad for IBIS, part of the AccorHotels hotel chain.

How do you think SFR ($14billion of revenue in 2015) or AccorHotels ($6 billion of revenue in 2015) willfeel whenthey learn that their ad budgets are being stolen, and used to finance piracy? Google's spin doctors will have to work nights and weekends to sort this quagmire out.

This is the end-game scenario. The subprime online ads bubble will go on, for as long as advertisers keep pouring ad budgets into automated ad placement, without asking for detailed reports ofwhere the money is going. But when they realize the shady and criminalactivities they are financing, they will stop, and the bubble will pop.

It wouldn't be Google's first SNAFU. Back in 2011,Google settled with the Feds over illicit pharma ads, writing a check for $500 million. Here's an excerpt:

When the sting began in 2009, Google had in place policies designed to block illicit pharmaceutical advertising. Whitaker's orders were initially rejected under those policies. But Whitaker says Google sales reps helped him tweak his sites to skirt the rules.

"It was very obvious to Google that my website was not a licensed pharmacy," Whitaker told the [Wall Street] Journal."Understanding this, Google provided me with a very generous credit line and allowed me to set my target advertising directly to American consumers."

This traffic laundering schemeis but one of many misdemeanors rooted deeply in the ad tech ecosystem. The rise of ad exchanges and automated ad placement has multiplied the number of intermediaries, and made ad placement overly obscure and complex.If Google knows about this scheme, but still lets it happen, it's stealing from content creators. If Googledoesn't know, then it steals from its clients, by directing their ad budgets to criminal activities, and Google'swhole PRabout how intelligent itsuser profiling is, is a scam: Google isjust placing ads randomly on the Internet and lying that itknows what it'sdoing.


The good, the bad and the ugly ofthe online advertising industry

Advertising is about creativity. For decades, artists and marketers have created ad campaigns that made or broke products and companies.

The riseofad exchanges, real-time bidding and programmatic buying of ad space has opened the field forgeeks andanalytical types. The new ecosystem makes it look like an ad campaign isall about algorithms and data. It does have huge and legitimate benefits for a lot of people, as millions of independent content creators can make a living by monetizing ad space on their websites. Ads are a necessary evil if we want to keep the Internet free. However, we needproper controls, and better awarenessofthe system's shortcomings. The fraud and misdemeanors will only grow with time if we keeppretending that everything's fine.

There are still people who are doing an outstanding job, taking care of their clients, tracking and reporting the ways their ad budgets are being spent. The efficiency of ad exchanges is overblown. User experience is paramount, as content producers are at risk of losing their visitors when they give the advertisers the keys to their website, and theseget filled with slow-loading ads and popups. Advertisers' clients should ask for a paper trail of where exactly their ads are being displayed. They should be aware of the rise of bots, viewability fraud, fraudulent traffic and the reputational risk ofadvertising on shady websites.

Advertising intermediaries in return, should take the high road, andfocus on performance, quality, and accountability. A crash is coming, and those who are now chasing the easy dollar will be wiped out.


Roadmap & Playbook


This piece is a follow-up to our first articleGoogle: End of the Online Advertising Bubble. We have received an amazing amount of interest and feedback, and we felt like we needed to do more than outline the conceptual shortcomings of the system.

We also felt like we only did half of the job. In The Big Short, Michael Burry realizes that the subprimemortgage market is doomed, but he can't really explain why. Only a few insiders share his opinion, while everyone else thinks he's crazy. It's only when Mark Baumdiscovers the abandonedhomescovered in weeds and alligators swimming in the pool, that the spectatorsrealizethat something's very wrong.

So here's your smoking gun.
