Some Canadian media prepared for Facebook changes, may be "devastating' for others"

Facebook shares slip after News Feed overhaul

To try to keep you glued to Facebook, it regularly updates the formula that decides what posts you see.

More clicks mean the posts would move higher in people's news feeds, even if people don't really want to see them.

What does this mean for Pages and public content?

Facebook has been under fire for months over what it shows people and whether its site has negatively influenced millions of its users. Today, fake news, which allegedly affected the 2016 USA presidential election, is widespread on the social media platform all over the world. Last year, Facebook disclosed that Russian agents had used the social network to spread divisive and inflammatory posts and ads to polarize the US electorate.

"The most hard thing about this", Chavern said, "is that it will impact some publishers more than others, but it really emphasizes that all are subject to these Facebook rules and they can change whenever without much rationale and without much consultation". "We will also be looking for any signs that the weighting of news sites is politically motivated".

"We started making changes in this direction past year, but it will take months for this new focus to make its way through all our products", Zuckerberg wrote in his Facebook post. Shares tumbled more than 4 percent during trading on Friday. While publishers' and businesses' organic reach will decline with the algorithm update, that means the content users do see from businesses (organic or paid) could have a much bigger impact.

So arguably the company can afford to shift its focus a bit away from quarterly profit gains and metrics like "user engagement" that get advertisers salivating.

A warning by Zuckerberg that people could spend less time on Facebook in the short term as a result of the changes sent the company's stock $8.29 lower to $179.47. At least, that's what the company hopes. The company has long pushed users to spend more time on the social network.

"The research shows that when we use social media to connect with people we care about, it can be good for our well-being", Facebook CEO Mark Zuckerberg wrote in a post Thursday.

Facebook tweaked its news feed in 2014 to clamp down on "clickbait", posts with grabby headlines like "you won't believe what happened next" yet ultimately disappoint. Many creators who post videos on Facebook prompt discussion among their followers, as do posts from celebrities. "It has never been this black and white", Stelzner said. It wants people to feel better each time they use the social network. So yes, this is possible. In Groups, people often interact around public content. We gravitate toward people like us.

Facebook's artificial intelligence is certainly good enough to identify infant images, and let people choose to see fewer of them-or, if they wish, even more of them. Of course, this is hard to verify independently, since the company doesn't often show that data to outsiders.

That will leave businesses that want publicity on Facebook no choice but to spend more on advertising, and as a result prices will climb, predicted Eric Schiffer, chairman of Reputation Management Consultants, which advises corporate brands on social media. Smaller, less-known outlets, especially those that do not produce content on the platform (such as live videos), could face major financial losses from the move.
