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.
