Seeking to make Facebook Inc. advertising more interesting to consumers, the social network says it has rolled out two updates to the news feed to help show more relevant ads, while also testing a feature that would let brands set a time for their status updates—including exclusive offers—to disappear.

“When someone sees an ad that is relevant to them, it’s a good experience for them as well as the marketer trying to reach them,” writes Max Eulenstein, Facebook’s product manager, in a blog post

Facebook has begun asking users who click “I don’t want to see this” to hide an ad the reasons they’re hiding the ad.

“We’ve learned that the reason why someone hides an ad can be just as important as the hide itself,” Eulenstein writes in a blog post. “If someone doesn’t want to see an ad because it’s not relevant to them, we know we didn’t do a great job choosing that ad and we need to improve. If someone doesn’t want to see an ad because it’s offensive, it probably isn’t a good ad for other people on Facebook, either.”

Facebook says it has begun taking into account the reasons why people give for hiding an ad in its news feed algorithm. When it identifies a trend, it will present the ad to fewer people. “When we identify an ad like this, we’ll show it to fewer people on Facebook,” Eulenstein says.

The social network is also weighing feedback differently based on how often a consumer hides ads or other news feed content. “If someone hides things very rarely, we’ll consider that when we choose what to show them,” Eulenstein writes. “If we think there is even a small chance they might hide an ad, we won’t show it to them. This affects the type of ads we show everyone, but has a bigger impact for people who don’t often hide ads.”

The news feed changes won’t impact most marketers’ ad delivery or how often their ads perform, Facebook says. But it should help the social network show users ads that more relevant to them.

Facebook also says it is testing a feature that would let users set a time for their posts to disappear, a spokesman says.

The tool could eliminate the need for a marketer to manually delete a special offer on his brand page that he didn’t want to live online forever.

The feature takes a page from Snapchat, which lets consumers and brands send messages that disappear after a set time.
