The Siteimprove CMS Extension bridges the gap between the Sitefinity content management system (CMS) and the Siteimprove Intelligence Platform. Now you can scan your website for errors as soon as a page is published, allowing you to fix mistakes, optimize content, and manage your site more efficiently.

What does it do?

The seamless integration between Siteimprove and Sitefinity streamlines workflow efficiencies for your web team. With the extension, your team can fix errors and optimize content directly within the editing environment. Once the detected issues have been assessed, you can re-check the relevant page in real-time and determine if further actions are needed. 

The Siteimprove CMS Add-On provides insights into*:

  • Misspellings and broken links
  • Readability levels
  • Accessibility issues
  • High-priority policies
  • SEO: technical, content, UX, and mobile
  • Page visits and page views
  • Feedback rating and comments
  • Get insights into the impact of unpublishing a specific page.
  • URL Shortener data and its impact on your digital assets

Review impact before unpublishing

You can now use the plugin to check if unpublishing a page will have an impact on your site. For example, you'll be able to see if deleting a page will affect your SEO, or if users would lose access to important documents and links.
If the plugin identifies any potential issues, you'll be able to make informed changes if you decide to unpublish a page. Read more about our CMS plugin
