Does varying the time of day for scheduled posts help with engagement?

This does not matter as much as following the Facebook warm-up process. The key is consistent engagement rather than the specific time of day.

Also, don't forget to register for our weekly live Group Mentorship sessions. They are key for getting extra help and deepening your understanding of the program. You will automatically receive weekly invite emails on Tuesday of each week with email subject lines that always begin with "[AdV] - REGISTER" where you can register for each week's calls.
