(SAN FRANCISCO) -- Google removed more than 350 million 'bad' ads from its system in 2013 in a continued effort to stop bad advertising practices and protect users on the Internet.
The findings, published by the tech giant on Friday, detailed a significant increase in removal from 220 million last year. Google attributes the growth to the improvement of the company's detection systems and expansion of online advertising.
The number of advertisers disabled declined, dropping from 850,000 in 2012 to more than 270,000 in 2013. This is due in part to scammers searching for less-secure targets, the company said.
Efforts aren't just being made to thwart bad ads. Google seeks to maintain a "healthy ads ecosystem," which means preventing good ads from funding bad content. In the past year, the company blacklisted more than 200,000 publisher pages from serving ads and removed more than 250,000 ad-funded accounts for policy violations.
Examples of bad ads included those promoting get-rich-quick schemes, illegal online pharmacies and those trying to sell counterfeit goods.
