250 Million Ads Rejected at Bing
Bing revealed recently that it rejected over 250 million ads, blocked 50,000 websites and banned 150,000 advertisers in 2015.
The performance advertising space has long been subject to "bad actors" and search engines are constantly on the lookout for problematic participants in their programs.
Tech support scams, according to Bing, are still a major problem. In fact, Bing blocked more than 15 million ads and 25,000 sites promoting illegitimate third-party tech support services.
Bing has relatively lax trademark usage policies, but says it still dismissed more than 50 million ads last year for trademark infringements. Phishing attacks and ads for pharma and counterfeit goods were also at the top of the list. Additionally, more than 3 million misleading pages and 30 million ads were blocked for spam and misleading content.
"At Bing Ads, we take the safety and security of our search users very seriously," wrote Darshat Shah and Neha Garg of the Bing Ads team.
"We start with an extensive team of domain experts who are up-to-date with latest attack patterns, as well as an operations team that is constantly refining policy enforcement to keep the ecosystem clean from new threats and compliant with laws in 40+ countries and multiple languages. In addition, we incorporate escalations from users and advertisers into policy enforcement improvements. Coupled with an extensive backend infrastructure, we work 24/7 to ensure ads that are shown are policy compliant and safe for our users. Each and every ad entering the system is scanned using automation powered by machine learning and then manually reviewed when necessary to ensure correct policy decisions."
