FB makes this EdgeRank metric Public (shown on every page) - now how to access it to collect stats?
Facebook calls this "Stories"... Here's how you get it:
https://graph.facebook.com/PAGE_ID/insights/page_stories/day?access_token=ACCESS_TOKEN
So, you will replace PAGE_ID with the page ID you want to gather the data from... and then ACCESS_TOKEN with the access token.
You can also change the /day? to either /week? or /days_28? to gather that data specifically...
Other options for the story telling insights are:
page_stories page_storytellers page_stories_by_story_type page_storytellers_by_story_type page_storytellers_by_age_gender page_storytellers_by_country page_storytellers_by_locale
Hope that helps!
