If your idea is to start working on the creation of online content you can start by creating a free blog in WordPress. This article explains the steps to do so and how to create a blog in the WordPress content manager.
We create an account on https://wordpress.com/ and go to MY SITES. Once here we click on the bar on the left in ADD NEW SITE, and we give it the name we want.
Click on ADD, button next to SITE PAGES and create a page called BLOG and once finished we would click on PUBLISH. After PUBLISHING we would have to confirm that we are going to publish it at that time. With that, the BLOG category would already be created on our WordPress page and within that category is where we would publish the articles.
If we visit our website we would see at the top a button called BLOG. THE URL would be a subdomain, within the domain wordpress.com and it would be very easy for a visitor to go to that category of our page.
In this step we are going to create our first article for the BLOG category. To do this we return to the main menu and now click on ADD.
We created the entry and clicked as before on PUBLISH twice.
It must be said that it is a way to start publishing, but you work in a Subdomain of WordPress, and it does not have all the functionalities of this content manager. For example, plugins cannot be installed. If you want a professional WordPress page you would have to pay for that. You can pay directly to WordPress or talk to a hosting provider to have your website.
