Google said it also blocked 10,000 websites selling fake goods in 2015, closed 18,000 accounts that sold fake items and blocked 12.5 million non-compliant drug ads. In addition, Google blacklisted 30,000 sites selling weight-loss products, blocked nearly 7,000 phishing sites, banned more than 10,000 spam sites, reduced the number of junk downloads through Google ads by more than 99 percent, and resisted more than 17 million fake ads that misled and tricked people into interacting with them.

　　
Google's definition of "bad" ads includes ads that spread malware, promote fake or illegal products, and intrusive ads that block content.While Google does have policies that explain the various programs it licenses and bans, it does not prevent marketers and fraudsters from circumventing the rules.

　　
Google blocked 524 million bad ads in 2014, 214,000 advertisers, 350 million bad ads in 2013 and more than 270,000 advertisers. The company did not disclose the number of advertisers it blocked last year.

　　
Google blocked 25,000 mobile ads last year, in large part because marketers placed ads too close to the button, causing users to accidentally click on them. But last June, Google revealed that it was developing a technology to solve the problem. For example, if a user clicks too close to the edge of an ad, Google might decide that the click was an accidental click, not only by not jumping the user to the target page, but also by charging advertisers.

　　
Google says that for the 780 million malicious ads blocked in 2015 that broke the law, it would take a person 25 years to see them if they were viewed at a second's speed. It also said that the existence of these ads seriously damaged and affected the user's online experience. What's more, these ads can harm users.

　　
In addition, Google says that some ads can sometimes be offensive even if they provide useful, demand-related content, because they sometimes block what they want to see and sometimes, ignoring the wishes of users, and force them to direct them to advertisers' websites. In response, Google banned some ads that were highly offensive.

　　
In addition to advertising, Google terminates or refuses to work with bad websites and mobile apps that don't comply with Google's policies. In 2015 alone, more than 1.4 million applications for cooperation were rejected.

　　
In addition to using technology to block malicious ads, Google has introduced user feedback measures, google said. When a user believes that an ad violates Google's policies, they can resolve the issue by submitting feedback and informing the Google team in a timely manner. Or by clicking the "Close" button on your ad, the "Ignore this ad" feature will stop you from seeing certain types of ads.

　　
In addition, in 2015 Google introduced a new "Ad Settings" interface to help you better control your ad experience. By updating your interest settings, you can receive ads that are more in line with your needs, or block specific types of ads as a whole.

　　
While Google's move to block bad advertising is in the public interest, it is also in Google's own interest. If a netizen clicks on a fraudulent digital ad, it will have a negative impact on their willingness to click on the ad, which is clearly not in Google's interest.
