If the Siteimprove plugin in Kentico is not displaying any information after you have installed and logged in, you may need to enable the plugin in your Siteimprove settings:

Login to Siteimprove > Settings > CMS plugin > Agree to the terms and conditions > Save

Note: You may need to re-login to the plugin widget in the Kentico pages application after you have enabled the plugin in the Siteimprove dashboard.
