In total, the search giant took down 2.3 billion ads that violated its advertising policies previous year.
Google added new policies in 2017, and highlighted its efforts in this year's report, noting it took down ads on roughly 1.2 million pages, 22,000 apps and 15,000 sites for violating policies around misrepresentative, hateful or low-quality content.
This number is down from the when Google reported it eliminated 3.2 billion ads from its network.
The tech giant also terminated almost one million bad advertiser accounts, about twice as many it axed in 2017.
Google announced that they have removed 2.3 billion bad ads in 2018 for violations of both new and existing policies. Some policies include banning ads from for-profit bail bond providers and higher scrutiny on ticket resellers.
The company also launched 330 new detection classifiers to help detect bad ads at the page level, removing almost 734,000 publishers from its network and bad ads from a total of 1.5m million apps.
Google also kicked around 734,000 publishers and app developers off its ad network and completely removed ads from nearly 1.5m apps. The company removed more than 531,000 ads for bail bonds past year. For-profit bail bond services, addiction treatment services, third-party tech support, ticket resellers, cryptocurrency and some local services such as garage door fix topped the list of sectors Google focused on in 2018. That's about double the number as previous year, Scott Spencer, Google's director of sustainable ads, said in a blog post.
When it comes to fake news and the political sphere, Google shares that it had verified 143,000 election advertisements in the USA, thanks to a it rolled out a year ago.
Google also talks about how the company's new policy for election ads has helped the company prevent ad fraud and fake ads.
Google places ads in apps and on websites, and there, it took action to cut off publishers and developers' revenue. The real challenge going forward, judging by Google's updated policies, is keeping up with the evolving ways of these malicious actors.
