Everyone who blogs hits the wall every once in a while. With that said, now how can you bounce back with a renewed energy for posting?
First: Review every topic and subtopic that you've covered in the last three months. If you blog every day perhaps a month's review will be sufficient.
Second: Make a list of gaps that you find. For instance, have you just barely touched on a topic that deserves more coverage?
Third: Remember to talk to others about things in your field that really interest them. You may be surprised that something you take for granted is something that they would like to know more about.
Fourth: Expand your reading to related fields and what they are covering. This practiced regularly will broaden your knowledge base and bring new subjects to your attention.
Fifth: If you are a long copy blogger, think about writing occasional short posts. If you normally blog with short posts, consider sprinkling in a few longer ones. The variety may make your posts easier to produce and of more interest to your readers. Why? Not everyone is looking for in-depth on everything and those who are might grasp something new if you take the time to go long.
What you've just read is referred to in the industry as a listicle, which is just what you'd think. It's a summary of things that could each deserve their own article.
