Soon, you might not be able to see the number of likes on others' Facebook posts, videos and more as the social media giant is conducting a world-first trial aimed at boosting users' wellbeing. Facebook on Friday said it began hiding the number of "likes" for posts in Australia, a trial designed to ease social pressure that could be rolled out worldwide.

Account holders across the country will also be blocked from viewing the number of reactions and video views on other people's posts from Friday, but will still be able to see how people respond to their own.

"We don't want Facebook to feel like a competition," the company said in a statement. "This is a test to see how people engage with this new format. We hope to learn from this over time in order to see if we will roll this out more broadly." More than one billion people use Facebook worldwide, but the social media giant has come under pressure to combat the platform's impact on mental health.

In Australia, one in five children report experiencing cyberbullying, according to the country's eSafety commissioner. The problem received national attention last year when a 14-year-old girl — who starred in adverts of an iconic Australian hat brand — killed herself after being bullied online.

Facebook's decision comes after it launched a trial in July to hide "likes" on the company's other major social media platform, Instagram. What began as a test on Instagram in Canada was expanded to Australia, Brazil and several other major markets.

The Facebook trial was described as "a limited test in order for us to get some early learnings." "While this has been testing on Instagram, Facebook and (Instagram) are different surfaces and we will likely see different data come from this test." The social media giant did not confirm how long the trial would run for.

"We want to understand from people whether removing the total counts improves their experience, while also not limiting any positive interactions," said Mia Garlick, of Facebook Australia.
