Ad-tech giants typically promote practices surrounding so-called “brand safety.” But programmatic ad networks provide the primary financial foundations keeping junk news and misinformation websites in business. As of 2021, large brands spent an estimated $2.6 billion on programmatic advertising published by disinformation platforms. With the explosion of generative AI, this number is likely much higher today.
NewsGuard’s Reality Check recently published a report exposing the gap between ad-tech PR promises and programmatic realities (“These Ad-Tech Giants Claim to Protect Advertisers’ Brands. They Can’t Even Protect Their Own”). NewsGuard shows how major ad exchanges, such as Google, Amazon, Adobe, and Yahoo, post their own ads on disinformation websites. The ads appear in and monetize untrustworthy digital media that promote conspiracy theories, health disinformation, and pro-Kremlin propaganda.
The Illusion of Exclusion
Ad platforms market sophisticated blocklists and strict publisher standards to reassure Fortune 500 advertisers. Here are some examples of the types of exclusions the advertisers promote:
| Google Ads, Display & Video 360 use Content Theme Exclusions allowing its ad buyers to automatically blacklist placements next to specific verticals, such as “News (sensitive)” (crimes, controversial social issues), politics, religion, and “Health (source undetermined).” Google also offers filters that automatically cut off sites featuring extreme profanity, graphic violence, or recent tragic events. Advertisers can upload custom URL blacklists and block search queries associated with fraud, terrorism, or unvetted news sources. |
| Yahoo DSP (Demand-Side Platform) has a misinformation and deception ban. It specifically bans monetization for domains pushing election conspiracy theories, fraudulent claims, or imposter media layouts designed to mimic legitimate news outlets. Yahoo also uses inflammatory content exclusions intended to block ads from running alongside sites that leverage fear, violent tragedies, or inflammatory language meant to incite hate or division. |
| Adobe Advertising Cloud has a tiered globally blocked sites list. Adobe employs category filters to block sensitive topics like politics, religion, or specific competitors. Adobe also filters out fake system alerts, deceptive URL redirects, and misleading landing pages. And Adobe enforces mandatory exclusions of domains promoting hate speech, unverified medical claims, harassment, or illegal acts. |
| Amazon DSP has an AI and deepfake ban as well as content adjacency policies. Amazon also automatically restricts ad serving across third-party supply networks in sensitive categories like accidents, disasters, arms and ammunition, and hate speech. |
Ads in Practice
In practice, NewsGuard’s audit discovered thousands of blue-chip brand ads served directly alongside toxic content, including election falsehoods and unvetted medical claims on “red-rated” unreliable sites. These are sites that NewsGuard rates as not consistently adhering to basic standards of accuracy, accountability, and transparency. In sum:
“So far in 2026, NewsGuard … identified programmatic advertising for 45 major technology brands appearing next to 162 articles advancing provably false claims identified in NewsGuard’s False Claim Fingerprints database that were published on news websites.”

Among these are 45 ads for products sold by Google, Amazon, Yahoo, and Adobe. Examples include these:
- An ad for the Google Chrome browser ran next to an article suggesting black seed oil as a cure for cancer.
- An ad for Amazon’s Audible was published adjacent to false claims about Joe Biden authorizing force against U.S. citizens leading up to the 2024 election.
- An Amazon Fire TV ad ran beside an article falsely stating Minnesota Gov. Tim Walz signed a bill designating p#doph%ilia as a “sexual orientation”.
- Yahoo Search ads appeared on a pro-Kremlin site publishing disinformation on Ukrainian generals.
- Adobe Acrobat Pro ads ran next to an article claiming the 2020 U.S. presidential election was “stolen.”
CivicHaven contacted the press offices of Google, Amazon, Yahoo, and Adobe. They were asked for comment or to explain what improvements they may be developing. They did not respond.
The Incentive Problem
Programmatic advertising operates as an automated, opaque middleman pipeline that tends to prioritize programmatic scale over publisher integrity:
- Double-Dipping Revenue: Ad networks collect transaction fees from the brand buying the placement and the publisher serving it. This creates an inherent conflict of interest regarding ad bans on low-quality, high-traffic sites.
- Unsupervised AI Content: The issue is also complicated by the proliferation of Unreliable AI-Generated News (UAINS) sites: content farms operating with minimal human oversight. Many of these sites churn out cheap clickbait specifically engineered to host ad scripts from major ad exchanges.

Keyword Bluntness vs. Real Credibility
To date, brand-safety verification relies heavily on blunt keyword blocking, meaning the blacklisting of words like “attack” or “virus”. The problem is that such bans frequently demonetize legitimate, high-quality news outlets covering actual events. Meanwhile, sophisticated misinformation domains, which carefully format propaganda to look like mainstream news, easily bypass these surface-level filters to harvest ad dollars.
To fix this, ad-tech providers will need to secure complete transparency from advertisers. The ad servers must shift budget allocation toward domain-level credibility ratings rather than superficial keyword filters. Until then, ad-tech intermediaries will continue cashing in from both ends of the supply chain while inadvertently subsidizing the disinformation ecosystem.
Basic transparency can go a long way as well. Ad-tech platforms should provide advertisers with improved transparency about where their ads appear could help reduce advertising on disinformation websites. Platforms could also provide clearer and more trackable advertising metrics on misinformation outlets. 🟦
