"Bad ads" consist of any advertising that violate Google's advertising policies, including ad fraud, phishing scams, and malware. The firm said it paid publishers $12.6 billion in the year under review.

"Improving the ads experience across the web, whether that's removing harmful ads or intrusive ads, will continue to be a top priority for us", said Spencer. Google said it took specific actions against violating adverts involved in scraping; tabloid cloaking; malicious activity; malware and trick to click formats.

These websites earn a fee for referring new customers to these products but are lightly regulated.
In a what looks like a pre-emptive strike Google says it will add policies addressing ads in unregulated, overly complex, or speculative financial products like binary options, crypto-currencies, foreign exchange markets and contracts for difference (CFDs), an exotic financial bet.
