I did some more digging after my recent post discussing a kind of facebook optimization to improve chances of showing up in the News Feed (FB’s biggest viral point) and came upon a great post on Shoemoney.
The post on Shoemoney is only looking at Pages, but brings to light 2 very interesting points that will help understand your Facebook Page and how Facebook “ranks” it.
1) It would seem that Post Quality could be a good indicator of whether what you’re sharing on your Page is getting placed in News Feeds.
2) The Post Quality of a Page seems to be based on how Facebook is grading your page against similar Pages and their attributes (fans, etc).
I will say that I’ve noticed usually when having a Post Quality (PQ) of around 200 on one of the Pages we run at Talk, frequently those updates get pushed into the News Feed. I need to experiment a bit more, however, to see really what the kind of “breakeven” number may be.
The unfortunate side of this is all is that Profiles owners don’t have the same quantitative measure of whether their own shared items will become “Newsworthy”.
