Hi I need some information on facebook. I am running a facebook page. I always share content which includes links, videos & pictures. I have noticed that the pictures & then videos are highly "Liked" as compared to external links. Why this? Also, I have noticed that under each post I share, some content is shown more than the other s. This show information is given under each post which is displayed as "39 people saw this post" while if I share a pictures on the same time, it will say like "250 people saw this post" so I mean that some content is getting more focus than the other content. What policy is this? I need info on this formula of content sharing on facebook. Pls advice and help me. Thank you.
