Use a subdomain for testing
A demo subdomain is ideal when you are still choosing a template, editing content or showing the website to your team. It lets you move quickly without buying a domain on day one.
For example, a business can test a site on a StorefrontLab subdomain, collect feedback and confirm the structure before making a public launch decision.
Use a custom domain for trust
A custom domain looks more professional on business cards, social profiles, invoices and search results. It also makes the brand easier to remember and share.
If the website is part of your long-term business presence, connect a branded domain before running serious marketing campaigns.
Think about SEO continuity
Testing on a subdomain is fine, but your public SEO effort should focus on the domain you plan to keep. Once content is final, connect the custom domain, set canonical URLs and submit the sitemap.
If you change domains later, use redirects and update external links where possible.
The best sequence
Build and preview on a subdomain, publish the final version on a custom domain, then connect analytics and Search Console. This keeps launch friction low while still giving the business a professional public address.
