Get interviewed on podcasts, magazines, websites, fellow entrepreneurs, etc. Reach out and ask for the interview. Let them know how your interview can benefit their community.
Talk about your product, why you started your business, why your product, the whole story behind it, your journey - what you learnt, what you achieved, what mistakes you made.
Interviews are great because you don't need to constantly think of new content. It allows you to get in front of many communities and audiences = many eyeballs. It establishes you as an expert in your field. Plus you get to share your product and business everywhere. And interviews are free, because people are always looking for new content.
I hope this was helpful. Feel free to reach out if you have any questions.
