Blackberry benefits from the merging of its pages, as it makes all pages appear healthy with customer engagement regardless of region. For example, from the screenshots below, the U.S. page helps to bolster the Australia/New Zealand page’s PTAT by contributing to the total global PTAT. Global brands in the future could introduce a metric calculating the overall engagement ratio for all of their pages. For instance, Facebook could start to tell brands the percentage of region specific page contributions to the total PTAT.

No. 3 on this week’s list, Grammarly is a service which provides an automated proofreading for text. The company uses its page as a way to share pictures with jokes about proper punctuation and grammar. This strategy has caused many of their posts to go viral as you can see the post below has earned over 10k shares.

As for other pages on the list this week, Trident is No. 2, adopting global pages as well. No. 4 Wexley School for Girls, a new-media advertising agency with only 3,086 likes, went viral receiving over 358k comments for a picture of Santa. No. 7 Mozilla Firefox found much of its engagement after Christmas, highlighting its Android application for tablets and cellphones.
