As from PageLever
The chart above, using data from the advanced Facebook page analytics company PageLever, shows that for pages with large fan bases, the shortest post lifespan was 11 to 13 hours. The longest is 50 hours, which is over a weekend.
The ‘impressions’ are a much reliable way as they get updated in an irregular way. Likes are much more reliable, and tend to happen in larger numbers than comments. So likes are the best metric to watch for post-die-off.
