Ajaxify Comments – Ajax and Lazy Loading Comments


Skip page reloads and separate error screens when posting comments. Ajaxify Comments hooks into your native WordPress comment system and allows comment posting without a page reload. Lazy loading is also supported, which can help speed up your page load time.


Getting Started | Sponsor Us | Ajaxify Home

Ajaxify Comments hooks into your theme and improves the usability of the comment form by validating and adding comments without the need of page reloads. Users can remain on the page and interact with new comments as they’re posted. This plugin also supports lazy loading of comments, which can help speed up your page load time.


When submitting the comment form, WordPress by default reloads the entire page. This can be a disorienting experience for the user. In the case of errors in the comment (invalid email, duplicate comment, empty comment), these often require a separate error screen and the user has to use the back button to edit their comment. This can be a frustrating experience for the user. Adding to that, comments can be resource intensive, and can slow down your page load time.

With Ajaxify Comments, comments are posted without a page reload. If there are errors, the error message is shown immediately, so the user can correct their comment.

Ajaxify Comments also comes with lazy loading of the comments section. For a page with a lot of comments, this can speed things up considerably. You can load comments when the DOM is ready or when the comment section is scrolled into view.

Moreover this plugin includes an option to automatically refresh the comments on the current page while the user stays on your page without requiring a page reload. This can be helpful in busy comment sections where reply response time is important.

The following themes are supported out of the box:

  1. Astra
  2. Blocksy
  3. Divi
  4. Genesis
  5. Ollie
  6. GeneratePress
  7. Neve

Ajaxify Comments should be compatible with most block themes. If Menu Helper can’t find the selectors, please leave a support request.

Technical Note

Since the plugin hooks into the theme on client-side to intercept the comment form submit process, and to add new comments without reloading the page, the plugin needs to access the DOM nodes using jQuery selectors. The plugin comes with default values for these selectors that were successfully tested with WordPress’ default themes « Twenty Ten », « Twenty Eleven », « Twenty Twelve », « Twenty Thirteen », « Twenty Fourteen », « Twenty Fifteen », « Twenty Sixteen ». If required, the selectors can be customized to match your theme in the plugin’s settings.

Menu Helper is available to help you find the theme’s selectors.


Ajaxify Comments is community supported. If you would like to add or change anything about the plugin, please consider assisting with the development on GitHub.

I’m using WPML. How do I translate this plugin?

WPML is an advanced topic, but we’ve put together a guide to help you translate Ajaxify Comments using WPML.

Ajaxify Comments isn’t working when I install it. What’s wrong?

More than likely you need to set up your selectors. Selectors are an advanced topic, which is why we’ve created Menu Helper. Menu Helper will help you find the right selectors for your theme. Please see our Menu Helper guide for more information.

It’s a good plugin, but it didn’t work for me(flatsome theme) . After activating the plugin and lazy load, site comments were visible only to the admin and not to the guest user. After checking, I noticed that when I disable Cache Rocket, the comments appear for guests . The problem is probably the activation of « Delay JavaScript » in wp-rocket or the interference of such items from js files or two lazy loading same time..

From my experience I can say that this plugin is the Best Comment Optimization Plugin so far, without any bugs. I have tested « Ajaxify Comments Plugin » on two of my sites which are heavily loaded with comments. It instantly solved all my wordpress comment optimization related requirements in a second. It increased my website page speed by removing « Avoid Excessive DOM size » warning from Google page speed insights. The author of the plugin is very cooperative and seriously solves all problems raised by the users. I hope that the author never abandons this plugin, and keeps it updated regularly. All the Best!

This plugin is very useful. By default WordPress show missed filed error in a comment in a new page, this behaviour is not really nice on my point of view and, in some cases, made user loose text that was previously inserted in the fields. I tested this plugin with the « Hestia » theme but was not working so I created a support topic and the support is present and replied. This is a good point! I tested the plugin with another theme « Customizr » and works. This plugin is very useful.
