Writing high quality content for social media is about deciding on your goals. What action do you want your user to take? How will you compel them to take this action? And, if they have doubts what information will you provide to help prevent those doubts?
I find most people struggle with connecting with their audience with the right message at the right time. You don't know what works until you try a few different posts, right?. Today you see more video and picture posts doing well while text post are not as popular. You'll want to keep your character counts down when posting to Facebook or Twitter. More people today use their mobile device to look at social media so keep in mind that screen space is limited so keep it brief.
Next, you'll want to analyze your social media stats. For Facebook this is located under Insights and for Twitter it is analytics.twitter.com. Find out what time of day does your audience see your posts. This varies depending on where you live and time of day. I find that 8 am and 3 pm EST are the best times to post.
Finally, if the post is important enough for you, you should consider advertising on social media to keep the topic top of mind.
