By Sneaking Into Ads.txt Files, The 404bot Cost Advertisers $15 Million

For two years, the 404bot worked unchecked, exploiting a flaw in the ads.txt spec that cost advertisers $15 million in wasted video ads. The 404bot served 1.5 billion video ads, according to Integral Ad Science, which revealed the scheme Tuesday with a warning for the industry, including for publishers to audit their ads.txt files.

More Publishers Are Breaking Up With Resellers

Publishers of all sizes are cutting ties with programmatic resellers. Just as buyers are employing supply-path optimization to eliminate exchanges that provide little value, publishers are removing ad tech intermediaries that clutter their setups or harm monetization. By working with fewer partners, publishers are prioritizing control over their ad setup and site experience over the... Continue reading »

Meet Sellers.json: It’s Like Ads.txt, But For The Buy Side

First there was Ads.txt, then there was App-ads.txt. Now there are Sellers.json and OpenRTB SupplyChain Object Specifications. The two new specs, released for public comment by the IAB Tech Lab on Thursday, are both meant to help advertisers get a better understanding of whether the inventory they’re buying is legit and where it’s coming from....

2018: The Year Programmatic Cleaned Up And Grew Up

This year’s theme was transparency. Marketers wanted transparency so they could make better decisions. Marketers, agencies and DSPs showed increased interest in the programmatic supply chain. They wanted to know the rules of programmatic auctions and the fees involved in advance, not find out hidden practices afterwards. They also wanted to know where to tread... Continue reading »

How Ads.txt Took Down 3ve, As The FBI Took Down Its Creators

Over a year before the FBI brought down 3ve’s human creators, the ad industry rolled out ads.txt, an anti-domain spoofing standard that slowly throttled the botnet. 3ve visited spoofed domains and sold fake traffic to publishers and, when it was active, was responsible for 1% to 2% of all bid requests, according to Google product...

Heads Up, Fake Apps: Ads.txt Is Coming For You

Ads.txt is headed to the app ecosystem. What form will it take? That’s still shaking out. The IAB Tech Lab released guidance on Wednesday with several proposals for how to implement Ads.txt within an app environment.

Google’s Buy-Side Boss: ‘There Are Issues Preventing Us From Growing As An Industry’

Brad Bender will speak at AdExchanger's upcoming Industry Preview conference on Jan. 17-18, 2018, at the Grand Hyatt New York. Google’s rallying cry for 2018? Better and possibly fewer ads. While that theory may seem counterintuitive for a company whose revenues come almost exclusively from advertising, rethinking the ad experience may mean recutting standard formats or reducing...

Ads.txt research released Tuesday shines a new light on the extent of the harm done to major publishers by inventory resellers and lax supply chain standards. A joint study from Google, Amobee and Quantcast that examined Ads.txt data found rampant counterfeit inventory available to DSPs that seemingly came from 16 media companies, including Turner, The...

Will Ads.cert Be The IAB’s Next Big Inventory Clean-Up Play?

Both the adoption of Ads.txt and commercialization of blockchain solutions have the IAB optimistic about the prospects for Ads.cert, a follow-up to Ads.txt that uses cryptographic security measures to authenticate inventory. While Ads.txt helps authorize inventory sources, it doesn’t solve the authentication problem, said Neal Richter, CTO of Rakuten Marketing and co-chair of the IAB’s... Continue reading »
