Hi Guys,
Facebook updated the way News Feed function, adding a human layer in their evaluation process to get new insights for the Post Rankings.
The updated News Feed algorithm would take into consideration “both the probability that you would want to see the story at the top of your feed and the probability that you’ll like, comment on, click or share a story” ... and you guys know how important is the user engagement for a performance based marketing 
"In the official announcement, Facebook notes that:
“Pages might see some declines in referral traffic if the rate at which their stories are clicked on doesn’t match how much people report wanting to see those stories near the top of their News Feed. This update helps rebalance those two factors, so people are seeing relevant stories to them.”
Facebook’s advice on how to avoid any reach penalty as a result of this update is:
“Pages should avoid encouraging people to take an action (such as encouraging lots of clicks), because this will likely only cause temporary spikes in metrics that might then be rebalanced by feed’s ranking over time.”
In general terms, this only underlines Facebook’s common News Feed principles:
*Make your posts timely and relevant
*Build credibility and trust with your audience
*Ask yourself, “Would people share this with their friends or recommend it to others?”
*Think about, “Would my audience want to see this in their News Feeds?” "

It seems that Organic viewing, like stumbling a pon a post from a group is dead. You have to create something catchy and still advertising it a little and hope for it to pick up in shares and likes from the placement.
