The 8am rush: France's biggest timing trap

This is the flagship finding of the French data. Watch what happens between 7am and 9am:

French posting volume explodes at 8am: about 138,000 weekday posts in our sample went out in that single hour, five times more than at 7am. Everyone schedules for 8am, just before the French workday starts. And precisely because everyone does it, 8am posts underperform 7am posts (57 versus 70), and by 9am the average post does no better than mid-afternoon.

It comes down to who you are competing against, not the clock. LinkedIn hands every post a small first audience, and how that audience reacts in the first hour sets the ceiling on its reach. At 8am you are one of tens of thousands fighting for the same French commuter's attention. At 7am the same people are waking up and checking their phone, but your post is one of a handful in front of them. In France, the crowd is the obstacle, and an hour earlier walks right around it.
