How to Add a Facebook Like Button to Your WordPress Site (Step-by-Step)

Hey there, WordPress user! 👋 Want to get more likes, shares, and engagement on your website? Adding a Facebook Like button is a smart way to make it super easy for visitors to spread the word about your content on the world‘s biggest social network.

In this in-depth guide, I‘ll walk you through exactly how to add a Facebook Like button to your WordPress site step-by-step, using both a plugin and custom code. We‘ll also dive into some advanced tips and best practices to help you optimize your button for maximum visibility and engagement.

Why Add a Facebook Like Button to Your WordPress Site?

Before we get into the nitty-gritty of implementation, let‘s talk about why you‘d want to put a Like button on your site in the first place. Here are a few key benefits:

1. Social proof and credibility. When visitors see that others have liked your content, they view your site as more authoritative and trustworthy. In fact, 63% of consumers say they are more likely to trust a business with positive reviews and social interactions.

2. Increased engagement. Users are more likely to interact with and share content that has prominent social media buttons. One study found that posts with Like buttons get 3-5x more likes on average than those without.

3. More referral traffic. Every time someone likes one of your posts, it appears in their friends‘ News Feeds, driving brand new visitors to your site. Referral traffic from Facebook has increased 115% in the past year and shows no signs of slowing down.

4. Improved SEO. While Google has stated that social media likes and shares aren‘t a direct ranking factor, there is evidence to suggest that pages with high engagement tend to rank better over time. Plus, all those new backlinks from Facebook certainly don‘t hurt!

Bottom line: If you want to grow your audience, boost engagement, and drive more traffic to your WordPress site, you need a Facebook Like button. Now let‘s talk about how to actually add one!

Adding a Facebook Like Button Using a WordPress Plugin

If you‘re not super comfortable editing code, the easiest way to add a Like button is with a WordPress social media plugin. There are tons of great free and premium options out there – here‘s a quick comparison of a few of the most popular:

For this guide, we‘ll use Smash Balloon, which makes it incredibly easy to add a Facebook Like button and offers additional features like embedding a Facebook feed if you want to level up your integration.

Step 1: Install and activate the plugin

In your WordPress dashboard, head to Plugins > Add New and search for "Smash Balloon Social Post Feed". Install and activate the plugin.

Step 2: Connect your Facebook account

Once activated, you‘ll see a new "Facebook Feed" item in your WordPress menu. Hover over that and click on "Settings".

Click on the big blue "Connect a Facebook Account" button to link your site to Facebook and give Smash Balloon read-only access to your public posts and profile. Follow the prompts to select the Facebook page you want to link.

Step 3: Customize your Like box

Now that your account is connected, you can configure how and where your Like button will appear. In the left-hand menu, go to Facebook Feed > Customize > Like Box.

Here you can customize key settings and preview how your Like button will look, including:

• Choosing a small/large button
• Showing friend faces
• Showing your page cover photo and posts
• Setting custom width/height
• Using a light or dark color scheme

Play around with the settings until you‘re happy with how the Like button looks. You can leave the other plugin settings as their defaults for now.

Step 4: Display the Like button on your site

Alright, your Like button is ready to go – now it‘s time to actually add it to your WordPress site!

The simplest option is to check the box labeled "Show Like Box after every post" to automatically append the Like button to the bottom of all your posts.

If you‘d rather have more control over where the button appears, you can also use a shortcode to manually insert the Like box in specific locations. Just copy this shortcode:

[custom-facebook-feed likebox=true]

And paste it into any post, page, or widget where you want the button to show up.

That‘s it! Your new Facebook Like button should now be live on your site. Go ahead and give it a test click to make sure it‘s working properly.

Adding a Facebook Like Button Using Custom Code

If you‘re comfortable working with HTML and your theme‘s template files, you can also add a Facebook Like button by directly copying and pasting code snippets.

The advantage of this method is it gives you total control over the button‘s appearance and functionality without relying on a plugin. The downside is it‘s a bit more technical and not quite as user-friendly.

As Facebook advises, it‘s best practice to add your custom code via a child theme or plugin rather than directly editing your parent theme‘s files. That way your changes won‘t get overwritten when you update the theme down the road.

Step 1: Create a Facebook App ID

Facebook requires all sites using their social plugins to register an App ID for moderation and tracking purposes. Don‘t worry – the process is pretty quick and painless.

Head over to the Facebook for Developers site and click "Log In" in the upper right to access your account. Mouse over "My Apps" and select "Create App".

Enter an "App Display Name" (this can just be the name of your website) and contact email. Then click "Create App ID" to proceed.

On the next screen, under "Add a Product", hover over "Facebook Login" and click "Set Up". This will enable the platform and social plugins for the app.

Go to "Settings > Basic" in the left sidebar to grab your newly created App ID and App Secret. You‘ll need to add these to your WordPress site next. Keep this page open for easy reference.

Step 2: Install the code snippets

Now armed with your Facebook app credentials, open up your WordPress theme folder and create a new file called facebook-like.php. Copy and paste the following code into that file:

<div id="fb-root"></div>
<script async defer crossorigin="anonymous" src="https://connect.facebook.net/en_US/sdk.js#xfbml=1&version=v11.0&appId=YOUR_APP_ID&autoLogAppEvents=1" nonce="YOUR_NONCE"></script>

<div class="fb-like" data-href="<?php the_permalink(); ?>" data-width="" data-layout="button_count" data-action="like" data-size="large" data-share="true"></div>

Make sure to replace YOUR_APP_ID with your actual Facebook App ID from the previous step.

Next, open your theme‘s functions.php file (or ideally a functionality plugin) and paste in the following:

// Enqueue Facebook SDK
add_action( ‘wp_enqueue_scripts‘, ‘add_facebook_sdk‘ );
function add_facebook_sdk() {
    wp_enqueue_script( ‘facebook-sdk‘, ‘https://connect.facebook.net/en_US/sdk.js#xfbml=1&version=v11.0&appId=YOUR_APP_ID‘, array(), null, true );
}

// Add Facebook Like button to posts
add_filter( ‘the_content‘, ‘add_facebook_like_button‘, 20 );
function add_facebook_like_button( $content ) {
    if ( is_single() ) {
        ob_start();
        include ‘facebook-like.php‘;
        $like_button = ob_get_clean();
        $content .= $like_button;
    }
    return $content;
}

Again, replace YOUR_APP_ID with your Facebook App ID. The first block of code loads the Facebook SDK on your site, while the second function displays the Like button on your single post pages.

At this point, the Like button should be showing up below your post content sitewide, looking something like this:

Step 3: Configure Open Graph meta tags (optional)

You may have noticed in that screenshot that Facebook is pulling in a kind of generic image and description for the post. To control exactly how your content appears when liked or shared on Facebook, you need to add some custom Open Graph meta tags to your site‘s <head>.

I recommend using the free Yoast SEO plugin, which has built-in support for Open Graph tags. With the plugin installed, navigate to SEO > Social and open the "Facebook" tab.

Make sure the "Add Open Graph meta data" box is checked. Then fill out the remaining fields with your site‘s default title, description, and image. These will act as a fallback for any posts/pages that don‘t have a custom social preview set.

Now, when you create a new post, you‘ll see fields to add a custom title, description, and image for Facebook. Whatever you enter there will override the default data when that URL is shared.

Tips & Best Practices for Using Facebook Like Buttons on WordPress

We‘ve covered the step-by-step process for getting a Facebook Like button on your site. But there are a few additional tips and best practices I want to share to help you get the most value from your new social media integration:

1. Put the Like button where it counts. Think about your goals for adding a Like button and place it in high-engagement areas. For instance, if you want to drive post shares, include it near the top of your content or in a sidebar widget that‘s always visible.

2. Consider adding a share button too. Likes are great, but shares are even more powerful for driving click-throughs. Most of the WordPress plugins I mentioned earlier give you the option to enable share buttons alongside your Like button.

3. Prompt visitors to take action. Users are more likely to like or share when directly asked. Try adding a call-to-action above or below your Like button, such as "If you enjoyed this post, please like and share it on Facebook!"

4. Run like and share contests. To really jumpstart engagement, consider running a contest or giveaway on your site that involves liking/sharing to enter. Just be sure to follow Facebook‘s official contest rules.

5. Target your content sharing. Not every post needs to be blasted out to your entire Facebook audience. Use the targeting options in your Facebook page settings to share certain posts only with relevant segments.

Frequently Asked Questions About the Facebook Like Button

Before we wrap up, I want to address a few common questions that come up related to Facebook Like buttons:

Can I customize the Like button style?

Yes! The custom code method gives you full control over the button‘s CSS styling. Plugins like Smash Balloon also offer multiple pre-set button styles and customization options.

Do I need a Facebook page to use the Like button?

Nope, visitors will be able to like and share your content on their personal profiles without you needing a dedicated page. However, having a Facebook page for your website is a smart idea for branding and driving engagement.

What‘s the difference between the Like and Share buttons?

The Like button lets users quickly like your post with a single click. The Share button opens a pop-up where they can add a personal message and choose where to share the post (in their News Feed, in a group, on a friend‘s timeline, etc.)

Will Facebook likes help my WordPress SEO?

Facebook likes and shares are not a direct Google ranking factor. However, the additional traffic and engagement you get from Facebook can indirectly help boost your rankings. Plus, some studies have shown a correlation between social shares and higher search positions.
