Thinking about how to put a subscribe button on Facebook to grow your audience? You’re in exactly the right place. This guide will show you how to do it, walking you through every option available - from enabling a simple “Follow” button on a personal profile to setting up paid subscriptions on a Business Page for your most loyal fans.
First, it’s helpful to understand that the term “subscribe” on Facebook can mean a few different things depending on your goal. A decade ago, Facebook had a literal “Subscribe” button for personal profiles, but that has since been renamed to “Follow.” Today, your strategy depends on whether you're using a personal profile or a professional Business Page.
Here are the three main ways you can add a subscribe-style button, each serving a different purpose:
Let's go through the steps for each one.
If you're a public figure, content creator, journalist, or leader who uses their personal profile for professional purposes, enabling the "Follow" button is essential. It allows an unlimited number of people to see your public updates without you having to accept thousands of friend requests. It effectively turns your personal profile into a public broadcasting platform.
Setting it up is quick and easy.
And that’s it! Once you set this to Public, a "Follow" button will automatically appear on your profile for anyone who isn't already your friend. People who click it will see your posts that you share publicly, but they won't have access to content you share only with friends.
For any business, brand, or creator with a dedicated Facebook Page, the blue Call-to-Action (CTA) button directly under your cover photo is your most valuable piece of digital real estate. This button is designed to drive your audience toward the single most important action you want them to take. While there isn't one "Subscribe" option, there are several powerful choices that can achieve the same goal.
The best part? You can choose a CTA that perfectly aligns with your specific marketing objective.
Here are the best options for growing your audience and a little on when to use each one.
This is the most direct equivalent to a subscribe button. It’s a simple, low-commitment action for visitors. When they click it, they’re choosing to see your content in their feed, making it a great choice if your main objective is purely to grow your on-platform Facebook audience.
This is arguably the most powerful option for long-term brand building. Instead of just getting a Facebook follower, you get an email subscriber. Link this button directly to your newsletter or email list landing page. An email list is an asset you own, making it immune to algorithm changes. You can drive traffic, announce products, and build a relationship directly in people's inboxes.
If you're a video creator, this is a fantastic option. You can link this button directly to your YouTube channel, a recent video premiere, or a landing page that hosts your flagship content. It tells visitors exactly what to expect and sends them to the platform where your core content lives. This helps you build subscribers on multiple platforms simultaneously.
If you have an established community of dedicated fans, Facebook Subscriptions lets you monetize your content directly on the platform. This feature is for eligible Pages and allows your followers to pay a monthly fee in exchange for exclusive content, special access, and a supporter badge. When you activate this, Facebook adds an official "Subscribe" button to your page, making it clear how fans can support you.
Facebook's eligibility criteria for Subscriptions can change, but generally, you'll need to meet requirements related to:
Once approved and set up, the "Subscribe" button will appear, giving your most devoted followers a clear path to supporting your work.
Simply having the button isn't enough, you need to encourage people to click it. Here are three simple ways to increase your conversions.
Your Facebook cover photo is the first thing people see when they land on your Page. Use this space strategically. Create a design that subtly or directly points visitors toward your CTA button. You can add a small arrow or include a text call-out like, "Click 'Sign Up' below for our free email course!"
Don't be afraid to remind people about your subscribe or sign-up button. When you publish a post, finish your caption with a direct call to action. For example:
Show people the value of subscribing. If your CTA is "Sign Up," create a post about a recent newsletter that was particularly valuable. If your CTA is "Follow," make a quick video explaining what people can expect to see from you when they follow your page. Giving people a peek behind the curtain makes the click feel much more worthwhile.
Whether you're activating the "Follow" button on your personal profile, optimizing the call-to-action on your Business Page for email sign-ups, or monetizing with paid subscriptions, you have plenty of strong options to grow your audience on Facebook. Choose the method that best aligns with your goals, and don't forget to actively promote it in your content.
