We removed 100 bad ads per second
In 2017, we took down more than 3.2 billion ads that violated our advertising policies. That’s more than 100 bad ads per second! This means we’re able to block the majority of bad ad experiences, like malvertising and phishing scams, before the scams impact people. We blocked 79 million ads in our network for attempting to send people to malware-laden sites, and removed 400,000 of these unsafe sites last year. And, we removed 66 million “trick-to-click” ads as well as 48 million ads that were attempting to get users to install unwanted software.
Last year, we removed 320,000 publishers from our ad network for violating our publisher policies, and blacklisted nearly 90,000 websites and 700,000 mobile apps. We also introduced technology that allows us to better protect our advertisers by removing
Google ads from individual pages on a website that violate our policies. Last year, we removed 2 million pages for policy violations each month. This has been critical in scaling enforcement for policies that prohibit monetization of inappropriate and controversial content. In fact, after expanding our policy against dangerous and derogatory content in April 2017 to cover additional forms of discrimination and intolerance, we removed Google ads from 8,700 pages that violated the expanded policy.
