When you write articles on LinkedIn, you want to demonstrate your thought leadership, expertise, and industry knowledge. News and updates from your industry make good topics to write about.
You could also answer a question your audience has. What are the frequently asked questions you get when you meet someone from your network? If you’re a member of a Facebook group that contains your ideal clients, keep an eye out for questions that get asked over and over again. I keep a list on the notes app on my computer with ideas for blog posts and articles.
If one of your LinkedIn posts is getting a lot of [engagement(comments and conversation) from your network, that might be a good topic for a long-form article.
