A list format blog is a type of blog post that uses a list as its primary structure. The content of a list format blog post can vary widely, but the most common topics include top 10 lists, how-to guides, and resource roundups. List format blog posts are typically shorter and easier to read than traditional blog posts, making them ideal for busy readers who want to get straight to the point. In addition, the use of lists makes it easy to scan the content and find the information you're looking for.
