The company said it down more than 3.2 bn ads that violated its advertising policies in 2017, as well as blocking 79m ads in its network that attempted to send users to malware-laden sites. They dictate what ads are acceptable, and what aren't acceptable. It also blocked almost 90,000 websites and 700,000 mobile apps for policy violations. The spread of such activity has led platforms and networks to question the value of allowing cryptocurrency-related advertising and to clamp down on the same. It also removed 400,000 unsafe sites. Essentially this means that you can't serve ads if you're pretending to be a legitimate news website based in London when you're actually a content scammer in a different city.
The company did, however, say the ban also applies to content related to cryptocurrencies "including but not limited to initial coin offerings, cryptocurrency exchanges, cryptocurrency wallets and cryptocurrency trading advice".
Of the 1.7 billion ads, 79 million were attempting to send people to malware-laden sites - Google removed 400,000 of these unsafe sites a year ago.
Speaking to selected journalists via Video Conferencing on Monday, Monetized Products, Google Trust and Safety, EMEA, Jessica Stansfield, said digital advertising plays an important role in making the web what it is today - a forum where anyone with a good idea and good content can reach an audience and make a living.
"Bad ads" consist of any advertising that violate Google's advertising policies, including ad fraud, phishing scams, and malware. In 2017, Google blocked 650 sites for running ads alongside fake content, 12,000 sites for scraping or copying content from other sites, and suspended 7,000 AdWords accounts for tabloid cloaking violations (running news headlines but redirecting users to sites that sell dubious products).
As Google implement these new changes, the Google ad's network becomes a lot safer, resulting in websites and blogs not having to worry about the ads that appear via Google's Adsense program.
