4 months, 1 week ago: @annfurnivall @kc_kreative There is no one who actually gives a true Edgerank score. The site http://www.edgerankchecker.com gives a score but it’s really just a benchmark based on things that they made up.
Funny thing is Facebook just actually denied that the term Edgerank is real. Bizarre side note.
But there are the People Talking About This score and then you can divide it by the number of Fans you have to benchmark against other sites. For large sites, 2% is a decent, standard score. Smaller pages typically have a higher score running closer to 3-5%.
AgoraPulse has a barometer that you can compare to other Pages in your size range: http://barometer.agorapulse.com/ But I think a lot of their numbers are high personally.
