What are ranks?

I'm just curious because I've been here for a few months and I don't know exactly what a "rank" is. I see some of my pages have 100% rank or 87% --usually always starts at 47% but what is it and how does it grow?

Hi Kait, it grows based on visits and comments. It also needs a minimum number of days to reach 100%.

What Mira said, plus likes.  Those with a high page rank have been liked, commented, visited (which means probably shared), so the higher the rank the better the article, in theory.

My advice - pay little or no attention to them. I do suspect that there is a large element of internal likes in the calculation because I have pages which are popular with visitors, who don't feel compelled to comment because of the nature of the content and who obviously cannot give them a "Like"
