WordPress does provide a default comments system. However, many people find the default comments to be limited and hard to manage.
I've seen a lot of WordPress sites move to Facebook comments so that they can provide a better alternative. 
In this post, I'm going to show you how to run Facebook comments on your WordPress site.
Step #1. Install the Facebook Comments plugin
[*] Login to your WordPress site.
[*] Go to Plugins > Add new and search for "Facebook Comments".
[*] Click "Install Now" and activate the plugin
Step #2. Create a Facebook App ID
[*] Go to the Facebook Developers page.
[*] Click "Add a new app".
[*] Choose "Website".
[*] Type in a custom name for the app.
[*] Click "Create new Facebook app ID".
[*] Choose a Category, which in my case is "Apps for pages".
[*] Click "Create App ID".
Your app ID is almost ready!
In the next page, you will see a bunch of code. Look for the "appId" reference and copy its value without the quotation marks. This will be the ID to use in the next step.
[*] Scroll down and type the URL of your WordPress site.
[*] Then, click "Next" to finish this part.
Step #3. Add Facebook App ID to your WordPress site
Go back to your site's dashboard.
[*] Settings
[*] Facebook comments
[*] Type in the App ID from the previous step.
[*] Scroll down to click the "Save changes" button.
Step #4. End result
Visit one of your posts to confirm the Facebook comments plugin is indeed working!!!
With this current setup, your site now allows you to post Facebook comments, but also the regular WordPress comments below.
