Disqus offers a simple one-click installation that seamlessly integrates with WordPress, keeps users engaged on your site longer with a commenting experience readers love, brings users back to your site with web and email notifications, improves SEO ranking with user generated content, keeps spam out with a best-in-class anti-spam filter, and provides a single profile for commenting on over 4 million sites including social login support for Facebook, Twitter, and Google accounts.
