There may be times when you know that a large portion of your social media audience is online, but you don't have anything prepared. One of the best ways to eliminate this problem is to have multiple posts ready to publish and use a scheduling tool to post them when you want. This way you don't have to worry about running out of ideas when you need to post something, with plenty of time to brainstorm and create posts beforehand.
Getting many posts out of the way can free up time to focus on other aspects of your campaign while making sure that your account stays active on a consistent basis. You won't have to remind yourself when to post if you forget or find yourself distracted.
Many scheduling tools out there even include an algorithm that determines when your audience is online, providing suggestions about the best time to post. Once you find the right scheduling tool for publishing new social media posts, you can simply browse for appropriate topics, whip up a high-quality and engaging post, and schedule it for a time when most people following you are likely to see it.
There are plenty of high-quality tools you can use to schedule social media posts, including Moz's Zoho tool that digs deep into Twitter analytics and determine the best times to Tweet.
