NEW YORK — Facebook says it plans to marginalize what it considers to be “clickbait’’ news stories from publishers in its news feed, in another step to keep its 1.71 billion members regularly coming back to its social network.

In a change to its news feed algorithm Thursday, Facebook said certain types of headlines would be classified as clickbait, those that “withhold or distort information.’’ Those stories will then appear less frequently in users’ feeds, the company said.

“We want publishers to post content that people care about, and we think people care about headlines that are much more straightforward,’’ Adam Mosseri, Facebook’s vice president for product management for the news feed, said.

Facebook has been working to maintain the integrity of the news feed to keep users happy and spending as much time on Facebook as possible. The Silicon Valley company constantly tweaks its algorithms, and in June it made a sweeping set of changes that would rank publisher content in general less favorably in the news feed.

Thursday’s algorithm change is not the first time ­Facebook has cracked down on clickbait. In 2014, the company said it was moving to feature spamlike articles less prominently by looking at other factors, such as if a user has “liked’’ and then quickly “unliked’’ a story that appeared in the feed. Other factors, such as how much time people spent reading an article, also contributed to Facebook’s calculations.

Thursday’s announcement goes a step further. Facebook spent months classifying phrases commonly used in clickbait headlines. Mosseri offered examples like “The Dog Barked at the Deliveryman and His Reaction Was Priceless,’’ or “When She Looked Under Her Couch Cushions and Saw THIS . . . I Was SHOCKED!’’

The company’s algorithms then took note of the websites from which the articles were coming, and could detect patterns of traffic coming from those sites over time. That process was then automated, and content identified as clickbait will now appear lower in the news feed than before. Mosseri likened the practice to a kind of e-mail spam filtering process.

The move will most likely heighten the anxiety of publishers that rely heavily on Facebook for traffic and often complain about having little insight into the company’s decision-making on how its all-powerful algorithm functions.

The social network’s vast user base and sophisticated targeting capabilities allow publishers to reach new audiences far beyond the direct traffic a media company receives at its own site. As a result, Facebook has been able to largely dictate the terms on which it engages with publishers, which have few other options for distributing their articles.

Julie Hansen, president and chief operating officer of the online publication Business Insider, said it would take Facebook’s latest algorithm change under consideration.

“We don’t do what we consider to be clickbaity headlines,’’ she said, “but we’ll certainly consider Facebook’s guidance when we look to post our content onto Facebook and adapt the headlines if needed.’’

For now, Facebook said it planned to improve relationships with publishers by becoming more transparent about its news feed practices.

“It’s becoming clear to us how there’s a lot of anxiety over what we do,’’ Mosseri said. “I spend a lot of time trying to ease that anxiety.’’
