The main web page components to watch for web accessibility compliance are:

• Heading
• Image
• Link
• Color
• Data Table

After identifying the issue in the page content reported by Siteimprove, open your page in SharePoint site to fix, Save, and Publish the updated page.

For stand-alone web pages created outside of SharePoint, use your favorite web page editor to  fix the issues, and then re-upload your page to the SharePoint site. Please note: web pages uploaded to the Pages library must be published.

Last step: Go back to Sitei​mprove and validate your updated page. Make sure all the errors are successfully fixed and the page passes validation.
