i already posted a topic about this...
my country got explore feed and all marketers are suffering... all major pages are losing their engagement and reach because of that
there is a popular page here that has 300k+ likes and used to have about 20k+ likes and 200+ comments per post at least, now it has 500-2000 likes and 20 comments per post
people were busting their asses off to make great content and great pages just so that facebook can shut them down since they are not boosting posts and paying, because they did it by investing their skill and time instead of money...
now, to be in news feed, you have to boost posts or they will not show there
and dont say that it is not like that, because if it is not, you still did not get the full package explore feed like my country did...
facebook is testing this option in third world countries + my country which might be poor compared to other central european countries, but it is nowhere near third world
