Today we’re pleased to announce availability of the Page Diagnostics Tool for SharePoint. The Page Diagnostics Tool for SharePoint is a Chrome Browser Extension designed to help you identify potentially problematic Classic pages in SharePoint Online that may not be delivering optimal performance based on characteristics discovered about the page by the Page Diagnostics Tool.
The Page Diagnostics Tool works by comparing discovered characteristics of one or more Classic pages in SharePoint Online to known best practices and provides guidance to remediating those issues to ensure you are delivering the best possible experience across these pages. In addition to addressing performance of existing pages, the Page Diagnostics Tool can also be used to evaluate existing pages before they are published in your environment.
The Page Diagnostics Tool is currently available as a Chrome Browser Extension that can be downloaded directly or installed through the Chrome web store.
The baseline rules currently evaluated by the Page Diagnostics Tool are detailed below. Each rule has an associated “more info” link which will take you to the supporting page providing more insights on the rule.
For additional information on using the Page Diagnostics Tool and in-product help, you can also use the About link in the tool to get links to the “How to use this tool”, “Tune SharePoint Online Performance”, “Third Party Notice” in addition to a link to “give feedback” which links to the tools and extensions section in User Voice.
We look forward to your feedback as we continue to consider scenarios for future versions of the Page Diagnostics Tool for SharePoint.
