Google’s bad ads report for 2018 is
out, and according to Director of Sustainable Ads Scott Spencer, 2.3
billion non-compliant ads were taken down
for violating policies, almost 1
billion fewer than the 3.2 billion ads detected in 2017. Many represented malvertising
and phishing scams for tech support, bail bonds, garage doors and ticket
resellers, with phishing scams totaling 58.8 million.

To improve its lucrative ad
business and put an end to the scams, malware and abusive content that have plaguing
the company, Google’s team blocked bad ads on 1.5 million applications and 28
million pages. The credit for this achievement goes to the company’s newly
introduced machine learning algorithm as well as some serious manual reviews.

On a monthly basis, Google took
down 2 million non-compliant pages containing “dangerous and derogatory
content,” and ads on 8,700 pages violated the company’s April 2017 publisher policy
about “discrimination and intolerance.” Although the number of bad ads removed
is nearly 1 billion lower than last year, Spencer writes the number of
advertisers and publishers that don’t follow the rules has doubled to “1
million advertiser accounts and 734,000 publishers and app developers.”

Last year Google added “28 new
advertiser policies and 20 new publisher policies to combat new threats and
improve the ads experience online,” but now they’ve updated the policies to
“address ads in unregulated or speculative financial products like binary
options, cryptocurrency, foreign exchange markets and contracts for difference
(or CFDs)” and gambling, Spencer explains.
