Facebook has deprecated the old follow button, but there are still easy ways to add it. If you’re not comfortable with HTML or CSS, you can use third-party tools like Elfsight or SociableKit. They let you create a follow button without any coding, you just generate the embed code and paste it into your post. If you prefer a simple method, you can also just add a text link like "Follow me on Facebook!" and style it a bit if you want. Both options work depending on what you're comfortable with.
