Custom Domains

Master this essential documentation concept

Quick Definition

Custom domains are personalized web addresses that replace default platform URLs (like platform.com/your-docs) with branded URLs (like docs.yourcompany.com). They help documentation teams maintain professional brand identity while using third-party documentation platforms. This creates a seamless user experience where documentation appears to be hosted directly on the organization's domain.

Understanding Custom Domains

Custom domains allow documentation teams to replace generic platform URLs with branded web addresses that align with their organization's identity. Instead of directing users to platform-generated URLs, teams can create professional addresses that reinforce brand trust and provide seamless navigation experiences.

Key Features

  • Brand-consistent URL structure that matches organizational domains
  • SSL certificate management for secure documentation access
  • DNS configuration options for flexible subdomain setup
  • Automatic redirects from old URLs to maintain SEO value
  • Integration with existing domain management systems

Benefits for Documentation Teams

  • Enhanced professional credibility and brand recognition
  • Improved SEO performance with domain authority inheritance
  • Simplified user navigation and bookmark management
  • Reduced confusion about documentation authenticity
  • Better analytics tracking and domain-specific insights

Common Misconceptions

  • Belief that custom domains require complex technical setup when most platforms offer guided configuration
  • Assumption that custom domains significantly impact page loading speeds
  • Thinking that custom domains automatically improve SEO without proper content optimization
  • Misconception that custom domains eliminate the need for platform-specific features

Real-World Documentation Use Cases

Enterprise API Documentation Branding

Problem

A software company's API documentation hosted on a third-party platform appears unprofessional with generic URLs, causing developers to question the authenticity and reliability of the documentation.

Solution

Implement a custom domain (api-docs.company.com) that seamlessly integrates with the existing corporate website while maintaining the documentation platform's functionality.

Implementation

1. Purchase or configure subdomain through domain registrar 2. Set up DNS CNAME records pointing to documentation platform 3. Configure SSL certificates for secure access 4. Update all internal links and references 5. Set up redirects from old URLs 6. Test thoroughly across different browsers and devices

Expected Outcome

Developers experience consistent branding throughout their journey, leading to increased trust, better adoption rates, and improved perception of API reliability.

Multi-Product Documentation Hub

Problem

A technology company with multiple products struggles with fragmented documentation across different platforms, making it difficult for users to navigate between product docs while maintaining brand consistency.

Solution

Create a unified custom domain structure (docs.company.com) with subdirectories or subdomains for each product, all pointing to the same documentation platform but maintaining distinct product identities.

Implementation

1. Design URL structure (docs.company.com/product-a, docs.company.com/product-b) 2. Configure DNS records for main domain and any subdomains 3. Set up platform routing rules 4. Implement consistent navigation menus across all product docs 5. Create landing page for documentation hub 6. Update all marketing materials and product links

Expected Outcome

Users can easily discover and navigate between different product documentations while experiencing consistent branding, resulting in improved user satisfaction and reduced support tickets.

Customer Support Knowledge Base Integration

Problem

A SaaS company's help documentation hosted on a generic platform creates a disjointed experience when customers navigate from the main website to support resources, breaking brand continuity.

Solution

Deploy custom domain (help.company.com) that matches the main website's design and navigation, creating a seamless transition from product to support documentation.

Implementation

1. Set up help.company.com subdomain with appropriate DNS configuration 2. Configure platform to use custom domain 3. Implement CSS customizations to match main website design 4. Add consistent header/footer navigation 5. Set up analytics tracking with same domain property 6. Create cross-links between main site and help docs

Expected Outcome

Customers experience uninterrupted brand journey from product exploration to support, leading to higher self-service rates and improved customer satisfaction scores.

Partner Portal Documentation

Problem

A B2B company needs to provide partner-specific documentation that appears professional and trustworthy while using a cost-effective documentation platform, but generic URLs undermine credibility in partner relationships.

Solution

Establish a custom domain (partners.company.com) with access controls and branded experience that reinforces the company's commitment to partner success.

Implementation

1. Configure partners.company.com with DNS provider 2. Set up documentation platform with custom domain 3. Implement authentication and access controls 4. Create partner-specific branding elements 5. Organize content with partner-focused navigation 6. Set up analytics to track partner engagement

Expected Outcome

Partners perceive higher value in the relationship due to professional documentation experience, leading to improved partner satisfaction and stronger business relationships.

Best Practices

✓ Choose Intuitive Subdomain Names

Select subdomain names that clearly indicate the purpose and are easy for users to remember and type. The subdomain should align with user expectations and organizational naming conventions.

✓ Do: Use descriptive subdomains like 'docs', 'help', 'api', or 'support' that immediately communicate the content type
✗ Don't: Use cryptic abbreviations, numbers, or overly long subdomain names that are difficult to remember or type

✓ Implement Proper SSL Certificate Management

Ensure secure connections by properly configuring SSL certificates for your custom domain. This builds user trust and meets modern web security standards while supporting SEO rankings.

✓ Do: Use automated SSL certificate renewal and monitor certificate expiration dates regularly
✗ Don't: Ignore SSL warnings or use self-signed certificates that create browser security warnings

✓ Set Up Comprehensive URL Redirects

Create proper redirect strategies to preserve SEO value and user bookmarks when transitioning from default platform URLs to custom domains. This ensures no content becomes inaccessible.

✓ Do: Implement 301 redirects from old URLs and create a redirect mapping document for reference
✗ Don't: Leave old URLs broken or use temporary redirects that don't pass SEO authority to new URLs

✓ Maintain DNS Configuration Documentation

Keep detailed records of DNS settings, including CNAME records, A records, and any special configurations. This documentation is crucial for troubleshooting and future maintenance.

✓ Do: Document all DNS changes with dates, reasons, and responsible team members in a shared knowledge base
✗ Don't: Make DNS changes without documentation or fail to communicate changes to relevant team members

✓ Test Cross-Platform Compatibility

Verify that your custom domain works correctly across different browsers, devices, and network configurations. This ensures all users can access documentation regardless of their technical setup.

✓ Do: Create a testing checklist that includes various browsers, mobile devices, and network conditions
✗ Don't: Test only on your primary development environment or assume configuration works universally without verification
