Facebook Scraper For Multiple Pages

Scrape multiple public Facebook pages en masse to help yield social analytics. Automatically fetch more detailed insights for owned pages' posts and videos to see what content strikes well. Go all the way back in time or specify two dates and watch the goodness happen at lightning speed via multi-threading!

Distinguishing Features

  • Multi-threaded for rapid data collection from multiple pages simultaneously (as many as you want!)
  • Collect detailed performance metrics on multiple owned business pages automatically via the insights and video insights endpoints
  • Retrieve number of public shares of a link by anyone across Facebook via the URL Object
  • Custom metrics computed:
    • Impression Rate Non-Likers (%): explore virality of your posts outside your typical audience
    • Engagement Rate: (Shares + Reactions + Comments) / Total Unique Impressions
    • Adjusted Engagement Rate (%) and Adjusted CTR (%): normalise rates across pages of different audience sizes and account for uncertainty in small numbers i.e. 5/10 CTR < 100/200 CTR as detailed by Evan Miller
  • Proper timezone handling

Sample Output

What can be collected from public page posts?

Post ID, Publish Date, Post Type, Headline, Shares, Reactions, Comments, Caption, Link

... and optionally with a performance cost:
Public Shares, Likes, Loves, Wows, Hahas, Sads, Angrys

What is additionally collected from owned page posts?

Posts

Video Views, Unique Impressions, Impression Rate Non-Likers (%), Unique Link Clicks, CTR (%), Adjusted CTR (%), Engagement Rate (%), Adjusted Engagement Rate (%), Hide Rate (%), Hide Clicks, Hide All Clicks, Paid Unique Impressions, Organic Unique Impressions

Videos

Live Video, Crossposted Video, 3s Views, 10s Views, Complete Views, Total Paid Views, 10s/3s Views (%), Complete/3s Views (%), Impressions, Impression Rate Non-Likers (%), Avg View Time

Setup

1) Add the page names you want to scrape inside PAGE_IDS_TO_SCRAPE

Grab the @'handles' or in url (e.g. 'vicenews' below).

2) Grab your own temporary user token here and place inside OWNED_PAGES_TOKENS:
Get Token -> Get User Token -> Get Access Token

OWNED_PAGES_TOKENS is the dictionary that stores the token(s) necessary to scrape public data. If the token is a permanent token for a business page, it is used to scrape private data provided that the page is placed in PAGE_IDS_TO_SCRAPE and its corresponding key is identically named in this dictionary.

3) Install python dependencies with pip install requests scipy pandas

N.B OSX users should have installed Homebrew and python with brew install python

Execution

Specify number of days back from present:

python get_fb_data.py post 5 (Public & owned pages)
python get_fb_data.py video 5 (Owned pages only for video-specific data)

Specify two dates (inclusive) in yyyy-mm-dd format:

python get_fb_data.py post yyyy-mm-dd yyyy-mm-dd
python get_fb_data.py video yyyy-mm-dd yyyy-mm-dd

The csv file is placed in the facebook_output folder by default
