Originally a contraction of the phrase “web log,” a blog is a type of digital publication in which one or more authors regularly post content, generally on a specific topic.

Many brands use a blog as a way to share engaging content with their audience and establish their industry expertise. The Hootsuite blog, for example, shares up-to-date content about social media marketing and how to use social tools.

“Blog” can also be a verb: When you write for a blog, you’re blogging.
