Alphabet's (GOOG) - Get Report (GOOGL) - Get Report Google unit said Wednesday it will impose some limits on political advertising by the beginning of 2020.

The move follows Twitter's (TWTR) - Get Report outright ban on political ads, going into effect this month.

Scott Spencer, vice president of product management at Google Ads said in a blog post that the company is "limiting election ads audience targeting to the following general categories: age, gender, and general location (postal code level)." However, "Political advertisers can, of course, continue to do contextual targeting, such as serving ads to people reading or watching a story about, say, the economy."

Spencer insisted that Google policies prohibit false claims "whether it's a claim about the price of a chair or a claim that you can vote by text message, that election day is postponed, or that a candidate has died." The company will, however, be "clarifying our ads policies and adding examples to show how our policies prohibit things like 'deep fakes' (doctored and manipulated media), misleading claims about the census process, and ads or destinations making demonstrably false claims that could significantly undermine participation or trust in an electoral or democratic process."

The new limits will go into effect in the UK ahead of next month's general election, in the rest of Europe by the end of the year, and in the U.S. by Jan. 6, 2020.

"We expect that the number of political ads on which we take action will be very limited -- but we will continue to do so for clear violations," Spencer wrote.
