Subdomain vs Custom Domain: Choosing the right domain strategy
For new site owners, is a custom domain worth the investment? Or is a free subdomain sufficient?
Comparison
| Aspect | Free Subdomain | Custom Domain |
|---|---|---|
| Example | your-site.github.io | yoursite.com |
| Cost | $0/year | $8-15/year |
| Branding | Unprofessional | Professional |
| SEO Control | Platform-dependent | Full control |
| Portability | Hard to move | Fully portable |
When You Need a Custom Domain
Personal Blog/Portfolio
Even for a personal blog, a custom domain's brand value and professionalism far exceed the $10/year cost.
Startup/SaaS
Mandatory. Using yourstartup.platform.com signals informality and harms conversion.
16IDC Takeaway
A domain costs $8-15/year — less than a coffee per month. But its impact on brand, credibility, and long-term development is enormous. Even the smallest personal project deserves a custom domain. Your domain is your site's permanent address on the internet — it shouldn't be a parasite on someone else's platform.
