An example of this is their Adsense policy introduced in late 2016 to take action on ads on misrepresentative content. Google have had long-standing policies prohibiting AdSense publishers from running ads on sites with dishonest content.
Google is joining Facebook in banning advertising for Bitcoin and other cryptocurrencies.

Facebook had banned all advertisements that promote cryptocurrencies to prevent advertisers from marketing "financial products and services frequently associated with misleading or deceptive promotional practices".
In China, paid advertisements and sponsored posts on cryptocurrencies have not appeared in major social networks and search engines following a ban on ICOs implemented past year by the country's central bank.
This year, it plans to add several new policies that "will address ads in unregulated, overly complex, or speculative financial products" like binary options, cryptocurrency, foreign exchange markets and contracts for difference.
At present, Google queries for terms like "binary options" and "buy bitcoin" produce four advertisements at the top of the results. Some aggressive businesses found a loophole: purposely misspelling words like "bitcoin" in their ads.
A Google spokeswoman said the company's policies will try to anticipate workarounds like that.
According to her, last year, Google removed 320,000 publishers from its ad network for violating the publisher policies, and blocked almost 90,000 websites and 700,000 mobile apps.She said the technology firm also introduced new technology that allows it to remove Google ads from more than two million URLs each month, adding: "Page-level enforcement technology allows us to better protect our advertisers by removing more ads from more sites while also minimizing the impact on legitimate publishers". That was up from 1.7 billion in 2016. This is because they are using new technology to remove more bad ads and sites. The company suspended 7,000 customer accounts for ads that impersonated a news article - what Google calls "tabloid cloaking" - and blocked more than 12,000 websites for copying information from other publications.
Of the 1.7 billion ads, 79 million were attempting to send people to malware-laden sites - Google removed 400,000 of these unsafe sites a year ago.
