The Six Companies Fueling an Online Ad Crisis

Suspect traffic vendors

As the controversy swirls over publishers selling advertisers bogus nonhuman traffic, many of the accused have screamed, “It wasn’t me! We bought bad traffic from somebody else!”

So, who are these traffic dealers? At Adweek’s request, close to a dozen industry experts—representing publishers, ad buyers, DSP and other ad tech execs—have identified six companies that they believe may be selling low-quality, potentially bot-generated traffic—starting at half a penny a click. They are AdOn, Adknowledge, eZanga, Jema Media, MGID and BlueLink Marketing.

One insider shared multiple URLs for bot-filled sites featuring AdOn as a traffic source. According to analytics generated by the firm SimilarWeb, eZanga and BlueLink are among the biggest referrers of traffic to Brightline Media’s and, as well as Bluefin Media’s GossipCenter—all bot-fueled sites identified in Adweek’s ongoing investigation. (It’s unclear whether these sites know where their traffic comes from.)

Harvard Business School professor Ben Edelman, who has tracked Web fraud for years, has cited Adknowledge for suspicious behavior in 21 different reports for his clients last year and six more this year. He’s flagged AdOn 10 times.

“Certainly AdOn, Adknowledge, Jema and eZanga sell plenty of non-user-initiated traffic, such as adware, popups, forced visits and the like,” he said. For most advertisers, this isn’t what they’re looking for. It’s the very opposite of targeted traffic.”

Edelman walked Adweek through an example of a site with ties to bots,, that received traffic from Jema and Adknowledge. In one case, the entire site’s home page, ads and all, was delivered to users within an iFrame—that is, the entire site was rendered invisibly as a user visited another site.

“Of course the advertisers and networks agreed to buy this traffic in anticipation of users being able to see the ads, click to visit advertisers’ sites, make purchases, etc.  None of that was possible here,” said Edelman.

Despite that example, the most infamous vendor of the bunch is AdOn, which last year was acquired by the British Web video firm Blinkx (which according to published reports has sold non-viewable ads in the past). “AdOn is just about the worst,” said one publisher victimized by bots.

“They are notorious for having the worst quality traffic in the industry,” said another publisher. “We worked with them very briefly several years back and dropped them immediately once we saw the overall quality. Just crazy traffic patterns, wildly inconsistent ad click rates, etc.”

Yet other vendors don’t have much better reps. “Adknowledge appears to be a total scam that is generating only fake impressions, whereas MGID is a legitimate blog network that seems to be juicing the numbers, maybe through leased bots,” said a DSP exec.

To be fair, Adknowledge does have its defenders. “They seem like a real company to me,” said one exchange buyer.

Adknowledge president Marco Ilardi emphasized that point exactly, noting that the firm has offices from New York to Shanghai. “We have 300 people and have invested millions in this business. We are not this company that is out there just trying to make a buck. In fact, we want to know about it if we have any traffic issues.”

Ilardi said that Adknowledge’s traffic can start at one-third of a cent but can run as high as 15 cents.

Meanwhile, MGID’s business operates a bit differently. The firm is known for providing referral traffic via a widget, albeit one that first redirects users to MGID’s own sites, then often sends them to completely irrelevant sites. Its come-ons include the promise that “We could supply your site with unlimited volumes of targeted traffic, so you will enlarge its audience even more and improve your ad revenue.”

One major exchange buyer claimed to have flagged MGID for suspicious behavior about a year ago and immediately stopped working with the company.

Naturally, MGID defended its practices. “Traffic that we send to websites consists of real Internet users who click on the content because they like it,” said a spokesperson.

Why do publishers need some much help getting extra traffic, anyhow? As one mid-sized site owner explained, advertisers won’t even entertain doing direct business with a Web company unless they reach a few million unique users. Those that don’t are forced to go the ad exchange route, where CPMs are sometimes painfully low. So many turn to buying traffic.

But buying quality traffic from a company like Google doesn’t pay off in bigger ad sales. So sites turn to cheap traffic vendors, even though they may not be sure where their traffic comes from. Even the "best" cheap traffic may come from links on domains based on misspelled URLs. “You’re marketing to morons, basically,” said a publishing exec.

There are numerous forms of bad traffic, according to insiders. Some of these vendors may sell pure bot traffic, or even hire humans in third-market countries to click on ads. Others bake entire websites into invisible 1×1 pixels that live on other sites. A few even mix good and bad traffic—a form of "impression laundering.”

Several of the companies Adweek’s team of experts has identified were tough to track down. For example, the majority of the email addresses on Jema’s website yielded bounce backs. Eventually, founder and CEO Jeff Long contacted Adweek, though he declined to name any of the company's advertisers or publishers. "Our servers block non-human traffic," he said. "I don't really want to talk about our pricing. It's not relevant." According to Jema's customers, it sells traffic for a tenth of a penny.

Others, once reached, vehemently defended their practices.

“Absolutely not,” said BlueLink CEO Declan Carney when asked if his company sells bot traffic. “We have a list of 8 million domains that we will not serve ads to. Does some get through? Absolutely it does. We try to minimize the percentage. We’ve got it down to 5 percent.”

Rich Kahn, CEO of eZanga, echoed Carney’s sentiments. Bots are a nuisance, but don’t define the business, he said. “I don’t care who you are,” he said. “Everybody in this business is touched by bot traffic at some point. And fraud isn’t unique today. Look at USA Today. More than half of its papers are delivered to hotel rooms, and people never pick up the paper.”

There’s plenty of debate in the industry over whether publishers who buy traffic from these vendors are really victims or at fault themselves. Or whether these companies are just fronts for even more shady players. Some wonder how you can blame an independent publisher for not understanding how ad networks work. But as one publisher put it, “Real publishers build an audience, they don’t buy it.”

Said another: “I’m fine with paying for traffic. I just want to reach humans, not R2D2 or C3PO.”

Edelman puts some of the burden on the publishers. “Clearly, Smartmomstyle knows it’s buying from Jema Media and Jema’s click fraud traffic and other low-quality traffic are well-known among traffic buyers. So I see plenty of cause to blame [sites like] Smartmomstyle as well as the traffic brokers.”

However, there’s a growing chorus of voices arguing that agencies and advertisers are complicit in this process. A buyer might even know that his client is running ads on lousy traffic and essentially juicing a brand’s performance metrics. “But how do you have that conversation about how bad a job you’ve been doing all along?” asked an exchange insider.
