There is no one-size-fits-all answer to this question, as the cost of hosting and maintaining a blog can vary depending on the size and content of your blog. However, some popular blogging platforms (including WordPress, Blogger, and Medium) offer free accounts that allow you to create a blog without having to pay any fees. Additionally, many blog hosting services (such as Bluehost and HostGator) offer affordable plans that include premium features such as domain name registration and private server hosting.
If you don’t want to pay for a platform or host, there are many free blogging platforms available, such as Tumblr, WordPress.com, and Blogging Plugins for WordPress.
Ultimately, the cost of writing a blog depends on your specific needs and preferences. However, if you’re looking for an affordable way to get started with blogging, many popular platforms offer free accounts that allow you to create a blog without having to pay any fees.
