Schedule the Content You Publish
Many people don't take into account the fact that their followers are from all over the globe, living in multiple time zones. If you post an image at 6 p.m. EST, your followers in Europe probably won't see it, because the vast majority of them will already be asleep when your post shows up. Before you publish any content, think about who you're trying to reach and what's going on in their part of the world.
Over time, you'll notice that content you publish at certain times of the day and on specific days of the week gets the most interaction. There's no universal schedule. Get to know your followers, and track your own levels of interaction (see Figure 7).
Figure 7 Posting content between 11 a.m. and 1 p.m. MST gives me the highest potential engagement on Google+.
