Facebook said on Wednesday that it will crack down on links to sites that contain an excessive number of ads or little substance.

The company announced that users would begin to see fewer links to “low-quality web page experiences” starting later in the day.

The move comes as the social media platform overhauls its news feed amid criticism that the site enabled the spread of misinformation during the 2016 presidential campaign.

“Similar to the work we’re already doing to stop misinformation, this update will help reduce the economic incentives of financially-motivated spammers,” the company said in a post on the website.

Facebook is using artificial intelligence to analyze past links that led to spam sites to determine whether new posts share similar characteristics. Links that are flagged by the system will show up lower in users’ feeds and may not be able to be used as an ad.

“We hear from our community that they’re disappointed when they click on a link that leads to a web page containing little substantive content and that is covered in disruptive, shocking or malicious ads,” the company said. “People expect their experience after clicking on a post to be straightforward.”
