How the best posting times are calculated
The windows come from aggregated studies of engagement by day and hour: Sprout Social (2024), HubSpot (2024) and Hootsuite (Q4 2024). Each platform has a handful of peak windows, scored by how strong engagement was relative to the platform's best slot.
These are the same benchmark values Social media studio uses as a starting point for new accounts. They describe audiences in general, not yours, so treat them as a first draft of your schedule rather than a rule.
