A free and open web is a vital resource for people and businesses around the world. And ads play a key role in ensuring you have access to accurate, quality information online. But bad ads can ruin the online experience for everyone. They promote illegal products and unrealistic offers. They can trick people into sharing personal information and infect devices with harmful software. Ultimately, bad ads pose a threat to users, Google’s partners, and the sustainability of the open web itself.



We have a strict set of policies that govern the types of ads we do and don’t allow on Google in order to protect people from misleading, inappropriate, or harmful ads. And we have a team of engineers, policy experts, product managers and others who are waging a daily fight against bad actors. Over the years, this commitment has made the web a better place for you—and a worse place for those who seek to abuse advertising systems for their own gain.



In 2016, we took down 1.7 billion ads that violated our advertising policies, more than double the amount of bad ads we took down in 2015. If you spent one second taking down each of those bad ads, it’d take you more than 50 years to finish. But our technology is built to work much faster.



Last year, we did two key things to take down more bad ads. First, we expanded our policies to better protect users from misleading and predatory offers. For example, in July we introduced a policy to ban ads for payday loans, which often result in unaffordable payments and high default rates for users. In the six months since launching this policy, we disabled more than 5 million payday loan ads. Second, we beefed up our technology so we can spot and disable bad ads even faster. For example, “trick to click" ads often appear as system warnings to deceive users into clicking on them, not realizing they are often downloading harmful software or malware. In 2016, our systems detected and disabled a total of 112 million ads for “trick to click,” 6X more than in 2015.



Here are a few more examples of bad ads we took action against in 2016:
