Please don't share outside of STM, this is internal data from the company I work for. This may come in useful for some of you guys when targeting on Facebook, or just for curiosity.
Data dump in this excel file - 2MB (limited release - no longer available)
We collected this data so we could like the top Facebook pages (for brands) in each country to increase our ad spying software's reach. If enough interest, we could work on adding categories, keywords and domains to this list.
Some interesting things to note:
If enough interest in Facebook data mining I may be able to release some more excels.
Something like, top 1,000 ads from Jan 2013, or top 100 from country XX.
Awesome!! Thanks bobliu! Can you share the top100 of germany?
Would LOVE the top 100 from United States
US and DE? Any other countries leave a comment and I'll see what I can do.
Fr 
Im interested in US and FR...
Thanks for the share mate, this is good timing for me 
Should make a tool from it, you have interesting data here!
wow thanks alot. this is great
Data for BE please 
Maybe this tool can also help:
http://us.socialnumbers.com/
SocialBakers.com has country level data as well. Do you have any idea on the Facebook page networks where we could leverage these numbers?
US, DE, FR, BE. Surprised no requests for AU/GB. I'll see what I can share.
Any other data mining/research I could release that people will find helpful?
Unfortunately I was told I'm not allowed to release the top ad data publicly at the moment - I'll keep pestering the decision maker, hopefully at some point in the future.
In the meantime I might be able to share some CPC excels. A drill down of Facebook click prices 2014 vs 2015 vs 2016. Let me know if that's of any interest, perhaps to find unexplored GEOs with a lot of cheap traffic. We all know how unreliable the click price data on Facebook can be, but it's a start.
This is great! Cheers!
Awesome - thanks a ton!
