A Comprehensive Comparison of WordPress Commenting Plugins

Share this article

Engagement, engagement, engagement.

My brother Lee and I are web developers and entrepreneurs. We try to capitalize on every opportunity available to increase user engagement. A critical part of any strategy aimed at improving user engagement involves allowing users to comment on website articles/blog posts. Commenting is possible on any WordPress site via WordPress’ default commenting functionality or by installing a third party plugin. However, WordPress’ default commenting lacks some important features that tend to increase user interaction. It also requires the installation of the Akismet plugin to keep your site’s comments spam free. In addition, there was recent news uncovering a cross site scripting bug (the 0 Day Bug) in WordPress’ commenting when Akismet is absent (but a patch has been released). For these reasons, we opt for alternatives to WordPress’ default commenting functionality.

We researched four popular third party WordPress commenting plugins: Disqus, Facebook, Livefyre and Google Plus. We delved into the user and admin features offered by each plugin, their configuration processes, and some shortcomings to provide an in depth comparison of your options.


Disqus Comments

Disqus

The Disqus Comment System plugin has the highest number of active installs of all of the plugins that we checked out (200,000+). At the time of writing, this plugin was last updated by Disqus on December 9, 2014, it is compatible with WordPress version 4.0.4 or below (but we used this plugin on version 4.1.5 and it worked great) and is rated 3.5 out of 5 by 80 people. The following websites currently use the Disqus Commenting functionality: wired.com, npr.org, politico.com, ew.com (Entertainment Weekly). You can find this plugin in the WordPress Plugin Directory at https://wordpress.org/plugins/disqus-comment-system/. Collectively, this information gives us a good indication of what we can expect from the plugin. The Disqus plugin will likely work reliably and consistently (even at high levels of traffic), will likely be supported/updated by the creators if bugs are found and its ubiquity likely points to its ease of use and implementation. However, we’re not going to let them off that easy; we need to see it to believe it. We installed and activated the Disqus Comment System plugin on a WordPress site. We documented the configuration process as well as the different user and admin features.

Configuration Process:

  1. Add, Install and Activate the Disqus Commenting System. Follow the onscreen instructions
  2. Sign in – Login via Facebook, Google plus or Twitter OR sign up for a Disqus account
  3. Add the site name and url that you’ll be adding Disqus Comments to in your Disqus account
  4. Select your site
  5. You are good to go! You should see a Disqus commenting box (like that shown below) on any blog post on your site.

Disqus Performance

Disqus had a total of 46 HTTP requests related to loading the commenting functionality.

Facebook Comments

Facebook Comments

Another commenting plugin that we checked out uses Facebook’s commenting plugin. You may not have heard of this little social network called Facebook ;). They have over 1.4 billion users and a $220+ billion market cap. According to the WordPress Plugin Directory, the most popular WordPress Facebook Comments plugin has 90,000+ active installs, a 4.5 out of 5 rating from 81 people, is compatible with WordPress version up to 4.1.4 (but we used this plugin on version 4.1.5 and it worked great) and was last updated on April 4, 2015. Facebook commenting is visible on techcrunch.com, espn.com and foxsports.com (and of course the functionality stems from Facebook’s internal commenting engine). This background provides a solid foundation for use; it shows that the plugin is likely easy and very reliable to use on the user and admin side (which we can attest to). You can get this plugin at https://wordpress.org/plugins/facebook-comments-plugin/ or use Facebook’s documentation to add it to your WordPress site. We installed the Facebook Comments plugin on a WordPress site and documented the configuration process as well as the different user and admin functionality.

Configuration Process:

  1. Create a Facebook App (choose WWW) at https://developers.facebook.com/apps
  2. Enter the App Id that you get after you create the app into the Facebook Comments Plugin settings page
  3. You are good to go! You should see the Facebook comments box (visible below) on all of your blog posts. You can disable the Facebook comments on each individual post by checking a box on each post edit page.
  4. *It’s important to keep in mind that if you use this Facebook commenting plugin you will want to disable WordPress comments on your site (otherwise both the WordPress default commenting and Facebook commenting will show up on the page). In order to remove the default WordPress comments, we recommend installing the WordPress Disable Comments plugin. Download the plugin at https://wordpress.org/plugins/disable-comments/, add it as a new plugin to your WordPress site and then activate it.
Facebook Comments Box

User Features

  • Allow users to comment on your blog post once they’re signed into their Facebook account or by signing up for Facebook. Users cannot comment using other login providers (used to be able to do this but can’t as of Graph API v2.3)
  • Responsive design to fit different devices – The commenting functionality is set to 100% width of whatever container it is in. So, how it looks depends on how well crafted the theme is.
  • Reply, edit, delete or like each individual comment
  • Threaded comments and replies
  • Users have ability to like, flag and reply to each individual comment
  • Comment sorting – by time, top (most active discussions are highlighted and spam is hidden and higher quality comments are bright to the top)
  • Increased exposure of your comments to the Facebook community (Not sure how much exposure you get out of this though)
    • Users can simultaneously post their comment and share their comment on Facebook by checking the box next to “Also post on Facebook.” This gives users the ability to easily share their activity with friends
    • If a friend comments on the same article that you commented on, you will get a notification alerting you to their comment.
    • If a user responds directly to your comment, you’ll receive a Facebook notification – alerting you to the reply.
    • Ability to Follow a Post (follow a comment) associated with an article (allowing you to keep up to date with a comment you’re interested in).
    • Ability to Unfollow a Comment (removing any additional notifications that you would receive).

Admin Features

How to Access: Sign into the Facebook Account that you used to create the Facebook App associated with the comments plugin. Then, you can either go to the following link https://developers.facebook.com/tools/comments OR click on the Moderator Tool link at a page of your site with the Facebook comments plugin. For more information check out the following link https://developers.facebook.com/docs/plugins/comments#moderation-setup.

  • Free to use
  • Create blacklisted words (could be Standard Facebook restrictions or a custom list)
  • Add/Remove Moderators
  • Ability to make all comments public by default and add to moderator view, make all comments public by default and add only comments with blacklisted words to moderator view, or make all comments hidden by default and add all comments to moderator view
  • Approve or Hide comments. You can approve or hide multiple comments at once using the checkboxes or the select all checkbox in the left column.
  • Set the default comment sorting (social ranking, oldest, newest).
  • Automatically correct common grammar mistakes
  • Always show the comments composer or collapse when there are greater than 5 comments
  • Create a list of banned users (they will still be able to comment but only them and their friends can see the comment).
  • The language of the comments plugin can be changed to fit the language of your site (these languages are supported http://www.facebook.com/translations/FacebookLocales.xml)
  • Set width of the plugin
  • Set color scheme of the plugin
  • Set number of comments to show
  • Technical Notes* You have the ability to add a class and a data-href attribute to an HTML element and it will output the number of comments associated that href. You can also Export Facebook Comments as a Backup. You could get all comments associated with a particular URL by using a Facebook Graph API call but it would be tricky for a non-technical person to figure out. Also, there’s not much else you could do with those comments (because you can’t import them into Facebook).

The list below outlines some functionality that is absent from Facebook Comments.

Shortcomings:

  • Don’t get email addresses associated with your commenters
  • Cannot add images to the comment
  • Cannot allow guests to comment
  • Cannot import existing comments
  • Comments are unable to be crawled and indexed by search engines (it doesn’t appear to be the case, but if we’re wrong feel free to correct us in the comments below)
  • Doesn’t have analytics.
  • Comments made with Facebook are NOT synced with your WordPress database (making it very very difficult to switch from Facebook comments to a different commenting solution and retain those existing comments)
  • Unable to delete comments from Facebook
  • Must have a Facebook Account or sign up for one to comment

Facebook Comments Performance

Facebook required 8 HTTP requests to load the commenting functionality on our demo site.

Livefyre Comments

Livefyre Comments

Livefyre Comments 3 is another popular alternative to WordPress’ default commenting functionality. Livefyre Comments 3 has 8,000+ active installs, 4 out of 5 stars from 4 users, was last updated on December 5, 2014 and is compatible with sites up to WordPress version 3.5.2. (We used this plugin on a WordPress version 4.1.5 site and it worked exactly as it should BUT the avatar image was too large for the design and overlapped a bit of the comment box. So, you should definitely stick to the listed compatibility on this one.). You can download this plugin from the WordPress Plugin Directory at https://wordpress.org/plugins/Livefyre-comments/. The following sites are using Livefyre’s commenting functionality: tennis.com, hootesuite.com, spinsucks.com and thecommunitymanager.com. Below, you can check out the configuration process for the Livefyre Comments 3 WordPress plugin along with a comprehensive list of user and admin features.

Configuration Process:

  1. Click on the confirm your blog configuration with Livefyre.com link at the top of your WordPress dashboard
  2. Login to your Livefyre account (or create one)
  3. Once Livefyre is done importing your existing comments, you’re good to go! Create a Facebook App at https://developers.facebook.com/apps

Google Plus Comments

Google Plus - Comments Evolved

The final WordPress Commenting plugin that we investigated is Comments Evolved for WordPress. The Comments Evolved plugin allows you to include several commenting options on your WordPress site via a tabbed interface. We just wanted to use Google Plus Commenting so we made sure that there was only one tab corresponding to Google Plus. While Google doesn’t officially support Google Plus Comments outside of use on Blogger.com, the creator of this WordPress plugin figured out a way to make it work on WordPress sites. This plugin has 10,000+ active installs , is rated 4.5 out of 5 stars from 65 people, was last updated on March 31, 2015, and is compatible with WordPress versions less than or equal to 3.6.1 (but we used it on a site with WordPress version 4.1.5 and everything worked as it should). This plugin can be found at https://wordpress.org/plugins/gplus-comments/.

Configuration Process:

  1. Once you’ve activated the plugin, make sure that the only value in the Tab Order input is gplus. If you have multiple values in this field, then your users will have multiple commenting options.
  2. Save Changes and you’re good to go!
  3. *It’s important to keep in mind that if you use this Google Plus commenting plugin mentioned below you will want to disable WordPress comments on your site. In order to remove the default WordPress comments, we recommend installing the WordPress Disable Comments plugin. Download the plugin at https://wordpress.org/plugins/disable-comments/, add it as a new plugin to your WordPress site and then activate it.
Google Plus Comments Box

User Features

  • Comment after logging into your Google Plus account.
  • Mention people in your comment
  • Comment Sorting – sort by newest and top comments as well as public comments versus only those in your Google Plus circle
  • Reply, +1 and Flag each individual comment
  • Link, Report Spam or Abuse, or Mute any comment
  • Edit, Link, Delete, Disable Replies to a comment thread that is authored by you
  • Responsive design to fit different devices – The commenting functionality is set to 100% width of whatever container it is in. So, how it looks depends on how well crafted the theme is.
  • Comments are able to be crawled and indexed by search engines

Admin Features

  • None. Since the Google Plus Comments are meant for Blogger.com, they offer moderation tools for Blogger blog authors (https://support.google.com/blogger/answer/3007766?hl=en). However, using Google Plus Comments on other sites is not officially supported and we couldn’t figure out a way to use the moderation tools on WordPress.
  • Free to use

Below is a list of the shortcomings of Google Plus Comments.

Shortcomings:

  • Doesn’t have any moderation functionality when used on a site other than Blogger.com.
  • Unable to create default comment approval settings.
  • Unable to delete, mark as spam, approve or hide comments from Google Plus.
  • Must have a Google Plus Account or sign up for one to comment
  • Don’t get email addresses associated with your commenters
  • Cannot add images to the comment
  • Cannot allow guests to comment
  • Cannot import existing comments
  • Doesn’t have analytics.
  • Comments made with Google Plus are NOT synced with your WordPress database (making it very very difficult to switch from Google Plus comments). So, if you decide to switch commenting plugins down the road, you will not be able to carry the comments made here with you to another plugin
  • Using Google Plus Comments on sites other than Google or Blogger.com is not officially supported by Google. So, if there are issues with use on other sites, Google may not fix them.

Google Plus Commenting Performance

The Google Plus plugin required 11 HTTP requests to load commenting.

In Conclusion

While you can use any of these commenting plugins, certain plugins prove to be much more useful than others in certain situations. For example, you may have existing WordPress comments and want to make sure they are carried on to your new commenting functionality. You will lose existing WordPress comments if you switch to Google Plus or Facebook Comments. However, Disqus and Livefyre have import capabilities for existing comments; making them the obvious choice in this circumstance. You may also have no existing comments but you want the flexibility to switch to a different commenting platform later. Again, you do not want to use Facebook or Google Plus Comments in this instance. We would suggest using Livefyre or Disqus. In choosing between Livefyre and Disqus, we would recommend using Disqus. Disqus offers more features, gives you access to the email addresses associated with all your commenters, has the most number of active installs and has a better design than Livefyre.

In all other situations, we would discourage you from using Google Plus. Google Plus has no moderation functionality and is not officially supported by Google for use on any site other than Blogger.com. The last updated date and the compatibility information are also strong indicators that you should not use Google Plus Commenting via the Comments Evolved for WordPress plugin.

So, Facebook, Disqus and Livefyre are your best alternatives to WordPress’ default commenting functionality. We tend to lean towards Facebook and Disqus because both are more ubiquitous than Livefyre, have functionality that we prefer and boast more of a modern and beautiful design. Facebook Comments has some simple and reliable admin functionality, but we prefer having the additional admin features that Disqus offers. But, Facebook is a staple and nearly everyone knows how their functionality works. We also love the prospect of easy and increased user engagement by users sharing their Facebook comments to Facebook and receiving Facebook notifications to continue their conversations on different comment threads. However, being able to share a conversation or comment on Twitter and/or Facebook, subscribe to a comment thread, add images to a comment, up or down vote a comment and recommend a conversation via Disqus provides more opportunities for users to engage with your website than Facebook comments. Lastly, Disqus is more open than Facebook Comments and provides more sign in and sign up pathways, the possibility of guest commenting and gives you access to all of your commenters’ email addresses. These features are incredibly valuable in building an engaged community.

So, at the end of the day, it’s hard for us lovers of user engagement not to land in the Disqus camp.

Continue the Conversation: We always love more insight, so please comment on which commenting plugin you love and why.

Frequently Asked Questions about WordPress Commenting Plugins

What are the key features to look for in a WordPress commenting plugin?

When choosing a WordPress commenting plugin, there are several key features to consider. Firstly, the plugin should be easy to use and integrate with your existing WordPress site.
