There are a lot of blog categories. Some popular ones are:
-Business
-Design
-DIY
-Food
-Lifestyle
-Real Estate
-Travel
-Home Improvement
There are many, many more. It really depends on what your blog is about. If you’re just starting out, it might be helpful to use some of these popular categories as a starting point and then research other categories that would be relevant to your blog.
Once you have a good idea of what topics interest you and what types of content your readers would appreciate, it’s easy to create additional categories. Just keep in mind that not all blogs will fit neatly into one category or another, so it’s important to focus on the content and audience of your blog rather than trying to shoehorn it into a pre-determined mold.
Ultimately, the number of categories that work best for a given blog is ultimately up to the individual blogger. There are no set rules or guidelines, so feel free to experiment and find out what works best for you and your readers.
