How to Set Up a Knowledge Hub for Copilot With Citations
Build a secure, searchable knowledge base that Copilot can reference with proper source attribution
What You'll Achieve
Deploy a governed knowledge hub in SharePoint that enables Copilot to answer questions with citations and respects permissions

- Identified content owners and governance stakeholders
- Basic understanding of SharePoint information architecture
Readiness Checklist
Before you begin implementation, ensure you have these items in place:
- SharePoint Online environment active with modern sites
- Content owners identified for each knowledge domain
- Content audit workshop scheduled with department leads
- Microsoft Purview available for content scanning
- Azure AD security groups defined for sensitive content
- Executive sponsor assigned to govern knowledge hub
- Budget allocated for content migration (2-4 hours per 100 docs)
- Metadata schema designed (Document Type, Department, Status, etc.)
- Naming conventions documented and approved
- Quarterly content review process agreed upon
Step-by-Step Guide
Audit and Inventory Existing Content
Find and catalog all knowledge sources across your organization
- Run a content discovery workshop with department leads to map where knowledge lives today
- Use Microsoft Purview to scan SharePoint, OneDrive, and Teams for duplicate or outdated content
- Identify authoritative sources: official policies, approved procedures, validated FAQs
- Mark content for migration, archival, or deletion based on relevance and accuracy
- Assess content quality: Is it current? Accurate? Formatted for readability?
- Document content owners and review schedules for each knowledge domain
Design Information Architecture
Create a logical structure that users and Copilot can navigate
- Organize by business domain, not org chart (HR, IT, Finance, Legal, Operations)
- Create hub site in SharePoint with clear naming: "Company Knowledge Hub" or "PolicyHub"
- Build 5-10 spoke sites under the hub, one per major knowledge domain
- Use consistent metadata: Document Type, Department, Last Reviewed Date, Status (Draft/Published/Archived)
- Set up managed metadata term sets for consistent tagging
- Define naming conventions for files: "HR-Benefits-Health-Insurance-2025.pdf" not "policy_final_v3.pdf"
Implement Permission Strategy
Control who can see what while enabling broad discoverability
- Default to broad read access: Most company knowledge should be accessible to all employees
- Use Azure AD security groups for sensitive content (Executive-only, Legal-only, etc.)
- Break inheritance only when necessary - complex permissions confuse Copilot and users
- Document permission rationale: Why is this content restricted?
- Test with non-privileged accounts: Can everyone see what they should? Can they NOT see what they shouldn't?
- Enable audit logging to track who accesses sensitive documents
Migrate and Optimize Content
Move content to the knowledge hub and format for AI readability
- Migrate content in phases: start with highest-value, most-accessed content
- Convert legacy formats (scanned PDFs, Word docs) to modern SharePoint pages or clean PDFs with text layer
- Add descriptive titles and summaries: Copilot uses these to determine relevance
- Structure documents with clear headings (H1, H2, H3) - AI models parse structured content better
- Add FAQ pages for common questions - these become high-value Copilot sources
- Create "last updated" metadata and schedule quarterly reviews with content owners
Configure Search and Copilot Integration
Optimize the hub so Copilot can find and cite the right content
- Promote the knowledge hub site in Microsoft Search so it ranks high in results
- Create search acronyms and bookmarks for common terms (e.g., "PTO" → PTO policy)
- Enable version history so Copilot can reference the current published version
- Add site description and keywords to improve discoverability
- Test Copilot with 20-30 common knowledge questions and verify it cites hub content
- If answers are wrong, refine content titles, summaries, or metadata
Govern and Maintain the Hub
Establish processes to keep content accurate and up-to-date
- Assign content owners with clear responsibilities: review quarterly, update as needed
- Create content lifecycle workflow: Draft → Review → Published → Archived
- Use Power Automate to send reminders when content is due for review
- Track usage via SharePoint analytics: What content is accessed most? What's never used?
- Run monthly Copilot quality checks: Ask test questions, verify citation accuracy
- Establish governance board that meets quarterly to review metrics and plan improvements
- Communicate updates: Newsletter or Teams announcement when major policies change

Common Pitfalls and How to Avoid Them
Copilot cites outdated or incorrect documents
This happens when old content isn't archived or marked as obsolete. Use metadata like "Status: Archived" and move outdated content to a separate archive site with restricted permissions. Copilot will deprioritize content it can't access or that has "obsolete" markers.
Content owners don't keep their sections updated
Content decay is the #1 knowledge management challenge. Assign clear ownership with executive accountability. Use Power Automate to send automated reminders 30 days before review due date. Publish a monthly "Content Health Report" showing compliance by department. Escalate to leadership if owners ignore reminders.
Users can't find content even though it exists in the hub
Discoverability depends on metadata and structure. Add descriptive titles, summaries, and tags. Create FAQ pages that link to detailed policies. Use search synonyms (e.g., "vacation" → "PTO"). Test search with actual user queries and refine metadata based on what fails.
Sensitive content leaks because permissions are misconfigured
Permissions are hard to get right. Default to simple group-based permissions via Azure AD. Avoid granting permissions to individual users. Test with non-privileged accounts. Use Microsoft Purview to audit sharing and flag overshared content. Review permissions quarterly.
Metrics to Track
Content Freshness
Percentage of documents reviewed within the last 6 months
Copilot Citation Accuracy
Percentage of Copilot answers that cite correct, current documents (measured via test question set)
User Satisfaction
NPS or satisfaction score from quarterly knowledge hub user survey
Search Success Rate
Percentage of searches that result in user clicking a result (from SharePoint analytics)
Content Coverage
Percentage of identified knowledge domains that have content published in the hub

Frequently Asked Questions
Should I use SharePoint or another platform for my knowledge hub?
SharePoint is the default choice if you use Microsoft 365 because it integrates natively with Copilot, Microsoft Search, and Viva. If you already have a mature knowledge base in Confluence or ServiceNow, you can connect those to Copilot via Microsoft Graph connectors instead of migrating.
How do I handle content that's confidential or legally sensitive?
Use Azure AD security groups to restrict access to specific user populations. Apply sensitivity labels (Confidential, Highly Confidential) to trigger DLP policies. Copilot respects these permissions and will not surface content users don't have access to. Always test with non-privileged accounts to verify.
What if our content is scattered across Teams, OneDrive, and SharePoint?
Copilot can search across all three, but scattered content creates duplication and version control problems. Establish a "source of truth" rule: official policies live in the knowledge hub, working drafts live in Teams or OneDrive. Use links to redirect users to the authoritative source.
How often should content be reviewed and updated?
It depends on change frequency. Regulatory compliance content may need quarterly reviews. General HR policies can be annual unless regulations change. Use metadata to track last review date and set reminders. Aim for 90%+ of content reviewed within the last 6 months.
Can I migrate content automatically or do I need to do it manually?
It depends on content quality and structure. If your existing content is well-organized with metadata, you can use SharePoint Migration Tool or Power Automate. If it's a mess, you may need manual curation to clean and restructure. Budget 2-4 hours per 100 documents for quality migration.
What happens if Copilot gives an answer based on old content?
This is a risk if content governance fails. Mitigate by archiving obsolete content, adding "Last Updated" dates to all documents, and running monthly Copilot quality checks. If an incorrect answer causes a problem, audit your content review processes and tighten governance.
