There is no one-size-fits-all answer to this question, as the answer will vary depending on the size, location, and audience of your blog. However, generally speaking, it is possible to have a free WordPress blog if you meet certain criteria.
To start with, your blog must be hosted on a WordPress site. This means that you will need to have a WordPress account and host your blog on a WordPress site.
If you already have an account and host your blog on a WordPress site, then all you need to do is add a free plugin to automatically generate and publish your blog posts.
Next, your blog must have at least 500 subscribers. This means that your readers must be interested in what you have to say and be willing to sign up for email notifications about new posts.
Once your blog has 500 subscribers, you can begin charging for access to your content via Patreon or other subscription services.
Finally, make sure that you are abiding by WordPress’s terms of service and copyright rules. For example, make sure that all of your content is original and does not violate any copyright laws.
If you are unsure whether any of your content violates copyright laws, then it is best to consult with an attorney before publishing it online.
