SharePoint Page Checker

A comprehensive Chrome extension for intranet authors and site owners to scan SharePoint (and compatible Office 365) pages for broken links, accessibility issues, and performance problems. Designed to help organizations maintain high-quality, compliant, and user-friendly intranet content.

What It Does
SharePoint Page Checker performs a complete scan of any SharePoint page and identifies:

Broken Links: Detects links that are inaccessible, return errors, or are misconfigured (including mailto: links and document links).
Accessibility Issues: Checks for WCAG compliance problems, including missing alt text, non-descriptive links, missing labels, heading structure, and more.
Performance Issues: Flags large images, slow-loading web parts, unoptimized formats, and other optimization opportunities.

How to Use

Navigate to any SharePoint (or compatible) page in your browser.
Click the SharePoint Page Checker extension icon in your toolbar.
Click “Scan Current Page”.
Wait for the scan to complete (typically 10–30 seconds).
Review your overall quality score and detailed results in the extension panel.

✅ Use hover feature – Locate issues quickly on complex pages
✅ Export regularly – Track improvements over time with CSV exports
✅ Share with teams – Use Copy feature to paste results into emails or docs

Common Questions
Q: Why can’t I see an “Input Without Label” issue?
A: Check the detailed information shown. It may be in a hidden or collapsed section, or in a web part configuration.
Q: Why do some links show as “Unknown (CORS)”?
A: Browser security prevents checking some external links. These links often still work—click them to verify.
Q: Why are working links flagged as needing target=”_blank”?
A: This is a best practice check. Links to documents and external sites should open in new tabs so users don’t lose their place on your SharePoint page.
Q: Are performance checks accurate?
A: Image size estimates are approximate. Actual file sizes may vary. Use as a guide for optimization priorities.
Q: Does this work on non-SharePoint pages?
A: Yes! The extension works on any webpage, though some SharePoint-specific checks may not apply.
Q: How long does scanning take?
A: Typically 10–30 seconds depending on number of links, images, page complexity, and network speed.
Q: Is my data collected?
A: No. All scanning happens locally in your browser. No data is collected, stored, or transmitted.
Q: Can I scan multiple pages at once?
A: Currently, scan pages one at a time. Navigate to each page and click “Scan Current Page.”
Q: What about Yammer content?
A: Yammer web part content is automatically excluded from checks since it’s embedded from an external service.
