There is no one-size-fits-all answer to this question, as the cost of running a WordPress blog will vary depending on the size, frequency of updates, and features offered. However, many popular WordPress hosting providers offer free plans that allow you to host a blog up to a certain size and number of posts. Additionally, many third-party providers offer free or discounted plans for bloggers.
So if you’re just starting out and don’t have an established readership yet, it’s likely that a WordPress blog will be free to operate. However, if you’re looking to grow your blog into a more comprehensive online presence, you may need to upgrade to a paid plan.
Ultimately, the cost of running a WordPress blog will depend on the specific needs of your site. So while it is generally free to create and host a WordPress blog, there may be additional fees associated with specific features or services required for high-traffic blogs.
