What Are Subdomains?
Basic Explanation
A subdomain is a prefix added to your main domain:
Main Domain:
yourcompany.com
Subdomains:
blog.yourcompany.com shop.yourcompany.com help.yourcompany.com support.yourcompany.com www.yourcompany.com (yes, www is a subdomain!)
Structure:
[subdomain].[maindomain].[tld] blog .yourcompany .com
Technical Details
DNS Configuration:
Subdomains are separate DNS records
Point to same or different servers
Appear as different websites to visitors
Share same root domain
Common Uses:
blog.site.com - Company blog
shop.site.com - E-commerce store
help.site.com - Support center
app.site.com - Web application
api.site.com - API endpoints

When to Use Subdomains
Perfect for Subdomains
✅ Use subdomains when you have:
1. Related Content on Different Platforms
Main site: WordPress (yourcompany.com) Blog: Ghost CMS (blog.yourcompany.com) Shop: Shopify (shop.yourcompany.com)
→ All get accessibility from one AllAccessible account
2. Separate Sections of Same Business
Corporate site: www.acme.com Product docs: docs.acme.com Customer portal: portal.acme.com
→ Different purposes, same company, one license
3. Regional or Language Variants
US site: www.company.com UK site: uk.company.com Canada: ca.company.com French: fr.company.com
→ Serve different markets with one accessibility solution
4. Development/Staging Environments
Production: www.site.com Staging: staging.site.com Development: dev.site.com
→ Test accessibility before production deployment
When NOT to Use Subdomains
Use Separate Sites Instead
❌ Don't use subdomains for:
1. Completely Different Businesses
❌ Business A: companya.com Business B: subsidiary.companya.com (different company)✅ Better: Business A: companya.com (Site 1) Business B: companyb.com (Site 2)
2. Different Branding Requirements
❌ Main brand: acme.com White-label client: client.acme.com (client shouldn't see acme.com)✅ Better: Use separate site: clientwebsite.com
3. Different Billing/Owners
❌ Your site: yoursite.com Client site: client.yoursite.com (they should pay)✅ Better: Separate site under their account
Rule of Thumb: If it should be billed separately or has different ownership, use separate site.
Subdomain vs. Separate Site Decision Matrix
Scenario | Recommendation | Reason |
Company blog | Subdomain | Same business, related content |
E-commerce store | Subdomain | Same business, different platform |
Help center | Subdomain | Same business, support function |
Staging environment | Subdomain | Testing for same site |
Client website | Separate Site | Different owner/billing |
Sister company | Separate Site | Different business entity |
Multi-language versions | Subdomain | Same content, different language |
White-label resale | Separate Site | Different branding/billing |

In Your Dashboard
Main Sites View:
Shows all your primary domains
Click a site to see its subdomains
Add subdomains to any site
Subdomain List:
All subdomains for a site
Individual settings per subdomain
Separate analytics per subdomain
Unified billing
Per-Subdomain Customization:
Each subdomain can have different widget colors
Different widget positions

Common Subdomain Scenarios
WordPress Multisite
Setup:
Main blog: myblog.com (WordPress) Author 1: john.myblog.com (WordPress Multisite) Author 2: jane.myblog.com (WordPress Multisite) Author 3: mike.myblog.com (WordPress Multisite)
AllAccessible:
Add main domain: myblog.com
Add subdomains: john, jane, mike
Install plugin once
Widget works on all subdomains
Cost: $10/month for all 4 sites
Shopify + Blog + Support
Setup:
Corporate site: company.com (WordPress) Store: shop.company.com (Shopify) Blog: blog.company.com (Medium/Ghost) Help: help.company.com (Intercom/Zendesk)
AllAccessible:
Main site: company.com
Subdomains: shop, blog, help
Each gets same accessibility
Different customization per subdomain
Cost: $10-19/month for all 4 sites
Regional/International Sites
Setup:
Global: www.brand.com (English) UK: uk.brand.com (English) France: fr.brand.com (French) Germany: de.brand.com (German) Spain: es.brand.com (Spanish)
AllAccessible:
Main: www.brand.com
Subdomains: uk, fr, de, es
Different default language per subdomain
Same accessibility features
Cost: $19/month for global accessibility (5 sites!)
Technical Considerations
Widget Behavior Across Subdomains
User Preferences:
Saved per subdomain OR globally (configurable)
User's accessibility settings on blog.site.com can carry to shop.site.com
Or each subdomain can have independent preferences
Widget Appearance:
Can be identical across all subdomains
Or customized per subdomain
Your choice
Analytics:
Track usage per subdomain
Or aggregate across all subdomains
Dashboard shows both views
Limitations and Requirements
What Counts as a Subdomain
✅ Included (Unlimited):
blog.site.com
shop.site.com
help.site.com
any-text.site.com
❌ Separate Site (New License):
differentdomain.com
site.differentdomain.com (different root domain)
site.co.uk (if main is site.com)
Key: Must share the same root domain
DNS Requirements
For subdomain to work:
Subdomain must be configured in DNS
Must resolve to a web server
Must be accessible via browser
AllAccessible Doesn't:
Create DNS records for you
Host your subdomain
Configure your web server
You Must:
Set up subdomain in your DNS
Have website running on subdomain
Then add subdomain to AllAccessible
