Suspending triple the number of advertiser accounts
As we shared in our 2020 report, we’ve seen an increase in fraudulent activity during the pandemic. In 2021, we continued to see bad actors operate with more sophistication and at a greater scale, using a variety of tactics to evade our detection. This included creating thousands of accounts simultaneously and using techniques like cloaking and text manipulation to show our reviewers and systems different ad content than they’d show a user — making that content more difficult to detect and enforce against.
We’re continuing to take a multi-pronged approach to combat this behavior, like verifying advertisers’ identities and identifying coordinated activity between accounts using signals in our network. We are actively verifying advertisers in over 180 countries. And if an advertiser fails to complete our verification program when prompted, the account is automatically suspended.
This combination of efforts has allowed us to match the scale of our adversaries and more efficiently remove multiple accounts associated with a single bad actor at once. As a result, between 2020 and 2021, we tripled the number of account-level suspensions for advertisers.
