Facebook will adjust the rules of flow algorithm to crack down on "Click-Bait". The title may use misunderstanding content to catch users' eyes to read the article on Facebook, but when you enter it, there is no related contents to support the title. This will be the first step to deal with users complains like "spammy and that they don't want to see".

Research Scientist Khalid El-Arini and Product Scientist Joyce Tang, who both work for Facebook, posted the content "with a headline that encourages people to click to see more, without telling them mush information about what they will see", this is a kind of spammy the Facebook will wipe out. "Posted like these tend to get a lot of clicks, which means that these posts get shown to more people, and get shown higher up in New Feed", they wrote.

Joyce Tang takes an example from Celeb Style Weekly, which was headlined - "You'll never believe which two stars got into a flight on the red carpet last night!! Click to find out which starlet they were fighting over!!". Facebook said that most of users hate such kind of headline, and 80% Facebook users "preferred headlines that helped them decide if they wanted to read the full article before they had to click through".

There are two ways to judge whether a report is "click-bait" or not. "One way is to look at how long people spend reading an article away from Facebook," El-Arini and Tang added, "if people click on an article and spend time reading it, it suggests they clicked through to something valuable. If they click through to a link and then come straight back to Facebook, it suggests that they didn't find something that they wanted".

The way that users interact with posted contents will also be analyzed by Facebook. "If a lot of people click on the link, but relatively few people 'like' or comment on the story when they return to Facebook, this also suggests that people didn't click through to something that was valuable to them," these two scientists explained.
