Rule details and solutions
When using iFrames (such as a link to a video on YouTube, a files that's located in a different document library than the site, etc.) the page load time will slow down because it takes SharePoint longer to retrieve the content. Avoid using iFrames where possible. If you must use an iFrame, learn more in best practices.
Improvement message: This page contains one or more iFrames. iFrames slow page performance because content is loading from an external source. Use images instead of iFrames whenever possible.
