This is more common than you might think so don’t worry, you’re in good company. 

Here’s my suggestion for you to get started, answer the most common questions that your audience wants to know. 

For example, take 5 questions that your audience wants to have answered and you could make one piece of content that briefly talks about each question or you can make a series of 5 pieces of content. That will allow you to give more complete and detailed answers. 

And to solve the question of where to start one of my favorites resources is answerthepublic.com. 

Go to answerthepublic.com, enter a keyword or two related to your audience and click search.

That will produce a vast amount of questions that real people are actually searching for so you can create a variety of content from those results. 

Let me know in the comments 3 items that you find which you plan to make content about. 

Good luck.
