Google removed over 3.2 billion ‘bad’ advertisements in 2017 – up from 1.7 billion in 2016 according to the company. The company removed the ads to avoid the ad network falling victim to malicious purposes.
A whopping 79 million ads were blocked on the network last year which sent consumers to malware-containing sites. Google also removed 400,000 of these sites.
In addition, the company blocked 66 million ‘trick to click’ ads which look like system warnings to most users in order to entice them to click the link.
Another 48 million ads were removed that tried to get users to install unwanted software.
However, that’s not all. On the publishing front, Google got rid of 320,000 bad publishers from its advertising network and blocked 90,000 websites and 700,000 mobile apps that violated its policies.
Over 7,000 ‘tabloid cloaking’ violation on AdWords accounts were detected. That’s an increase of 1,400 from 2016. Tabloid cloaking is when a website or content piece pretends to be news. However, upon clicking the link, users are taking to sites that aim to sell items.
Another 12,000 websites were removed for duplicating or copying content.
Google said that it added 28 advertising policies and 20 new publisher policies in 2017 in order to address threats from malicious or misleading ads and content.
In 2018, the company will focus on addressing speculative financial products such as cryptocurrencies.
