Google posted some of their Google Ads preventative measures from 2019 saying they blocked over 5,000 bad ads per minute last year. Google blocked and removed 2.7 billion bad ads, suspended nearly 1 million advertiser accounts, terminated over 1.2 million publisher accounts and removed ads from over 21 million publisher web pages.
Google did a lot of work on “trick or click” ads, saying “nearly a 50 percent decrease of bad ads served in both categories from the previous year. In total, we blocked more than 35 million phishing ads and 19 million “trick-to-click” ads in 2019.” Trick or click ads are ads designed to trick people into interacting with them by using prominent links (for example, “click here”) often designed to look like computer or mobile phone system warnings.
