Add Facebook or Disqus comments to your Kartra pages to encourage visitor interaction, boost engagement, and invite ongoing conversations.

Comment widgets let your page visitors leave replies and interact publicly, just like they would on a blog or social media post. You can embed these directly into your Kartra pages using third-party tools like Facebook Comments or Disqus.

These widgets are perfect for:

  • Blog-style content where feedback and discussion are encouraged
  • Event pages with real-time engagement
  • Product pages where social proof and testimonials drive conversions

Key details:

  • Quick Facebook Comments widget: Load instantly for visitors who are already logged into their Facebook account in the same browser.
  • Disqus Setup: Requires a one-time setup through your Disqus account, including retrieving and adding a Universal Code.
  • Disqus Compatibility: Once configured, the widget works across all modern browsers and devices.
  • Disqus Guest Commenting: To let users comment without signing in, be sure to enable guest commenting in your Disqus settings.
