This is one of the most important questions that every blogger needs to ask themselves. The best way to find your niche topic is by looking at the search engine results.   The last thing you want to do is to write about a topic that already has a ton of content out there and you will be competing with them for traffic.   Niche topics are what you are passionate about and experts in. It could be anything from food, fashion, health, or something else entirely.   If you have a blog related to SEO, then it would make sense for your niche keyword to be "seo blog" or "blogging tips."
