Engagement Heat Map: What do the colored squares mean?

• The green square represents the highest performing posting day/time for engagement historically.
• Dark purple squares represent the next best performing posting days/times for engagement historically. As the squares become lighter, engagement performance decreases.
• Grey squares represent days/times where the account received very little to no engagement historically, or did not post at all.

You can view the average engagement rate for any particular day/time by hovering over the square.
