Google shared statistical information about fighting with bad ads in 2015. There are so interesting numbers in the blog post written by Sridhar Ramaswamy, SVP, Ads & Commerce. Counterfeiters, Pharmaceuticals and Weight loss scams categories include so interesting numbers. This informations are very good to see the big picture of Darth Vader side.

No one can reject the importance of ads and their economical benefits to keep the web sites and mobile applications free. They are connecting products and services to the users. At the introduction part, it is stated that bad ads can ruin the entire user experience. Google coordinated a global team of 1000+ people dedicated to fighting bad ads. The number of disabled ads in 2015 is 780 million because of violating Google ad policies. Let’s look at the numbers from blog post writer’s own words ;

Busting bad ads

Some bad ads, like those for products that falsely claim to help with weight loss, mislead people. Others help fraudsters carry out scams, like those that lead to “phishing” sites that trick people into handing over personal information. Through a combination of computer algorithms and people at Google reviewing ads, we’re able to block the vast majority of these bad ads before they ever get shown. Here are some types of bad ads we busted in 2015:

Counterfeiters

We suspended more than 10,000 sites and 18,000 accounts for attempting to sell counterfeit goods (like imitation designer watches).

Pharmaceuticals

We blocked more than 12.5 million ads that violated our healthcare and medicines policy, such as ads for pharmaceuticals that weren’t approved for use or that made misleading claims to be as effective as prescription drugs.

Weight loss scams

Weight loss scams, like ads for supplements promising impossible-to-achieve weight loss without diet or exercise, were one of the top user complaints in 2015. We responded by suspending more than 30,000 sites for misleading claims.

Phishing

In 2015, we stepped up our efforts to fight phishing sites, blocking nearly 7,000 sites as a result.

Unwanted software

Unwanted software can slow your devices down or unexpectedly change your homepage and keep you from changing it back. With powerful new protections, we disabled more than 10,000 sites offering unwanted software, and reduced unwanted downloads via Google ads by more than 99 percent.

Trick to click

We got even tougher on ads that mislead or trick people into interacting with them—like ads designed to look like system warnings from your computer. In 2015 alone we rejected more than 17 million.

Creating a better experience

Sometimes even ads that offer helpful and relevant information behave in ways that can be really annoying—covering up what you’re trying to see or sending you to an advertiser’s site when you didn’t intend to go there. In 2015, we disabled or banned the worst offenders.
