What is a domain name? E-commerce definition
June 4, 2026
A domain name is the readable web address of your store: for example www.mamarque.fr or brand.com. It replaces the technical IP address of the server and becomes the digital identity of your brand. In e-commerce, owning your own domain (and not just boutique.myshopify.com) strengthens trust, branding, and e-commerce SEO.
Summary
Definition: domain name, URL and extension
The domain name is the central part of the address that an internet user types or clicks. In https://www.exemple-boutique.fr/collections/robes. https://: secure protocol (SSL certificate). www: subdomain (optional depending on configuration). exemple-boutique.fr: domain name (domain + extension). /collections/robes: path (URL path), not the domain.
Components of a domain name. SLD (Second Level Domain): the chosen brand (mamarque). TLD (Top-Level Domain): extension (.fr, .com, .shop, .store…). Subdomain: prefix (www, en, blog).
Useful distinctions. Domain name vs URL: the domain is the root address; the URL includes protocol, path, and parameters. Domain name vs domain authority: the domain is the address; the DA measures the estimated SEO reputation. Custom domain vs myshopify.com: Shopify provides yourstore.myshopify.com by default; the own domain replaces the public display. Domain vs hosting: the domain points to a server; Shopify hosts the store (SaaS). Registration vs ownership: you rent the domain via a registrar (OVH, Gandi, Namecheap…) for a duration (1 to 10 years).
Why the domain name is important in e-commerce
The domain is often the first contact with your brand after an ad, an email, or a packaging.
The essential points to keep in mind are the following. Trust: brand.com reassures more than a generic or marketplace URL. Branding: consistency across packaging, social networks, and invoices (D2C). SEO: history, backlinks, and content accumulate on a stable domain (canonical link). Professional email: contact@brand.fr adds credibility to customer service. HTTPS: SSL certificate linked to the domain, mandatory for payment and browser trust. Platform independence: you keep the domain if you change CMS (with migration). Apple Pay / Shop Pay: domain verification required for certain wallets.
Selling publicly on .myshopify.com without a custom domain often signals a draft or low-investment store. Serious merchants connect a domain before running ad campaigns.
Connect a domain name on Shopify
Configuration in Settings > Domains (Shopify Help Center).
Three options. Buy through Shopify: integrated registration and DNS management. Connect existing domain: modify DNS at registrar (A record + CNAME). Transfer domain: migrate registrar to Shopify (optional).
Common DNS settings for external connection. A record (@): points to Shopify IP (value provided in admin). CNAME (www): shops.myshopify.com or specified value.
Shopify tips. Define a primary domain (primary). Automatically redirect www ↔ non-www (only one canonical version). Check that SSL is active (HTTPS padlock) on all pages. Add the domain to Google Search Console. Enable auto-renewal at your registrar. Maintain registrar access (updated admin email).
DNS propagation: 24 to 48 hours after modification. Test in incognito mode before launching ads.
In summary
The essential points to remember are the following. Domain name = web address of the brand (e.g. brand.fr, brand.com). Distinct from full URL, domain authority, Shopify hosting. Key aspects: trust, branding, SEO, professional email, HTTPS. Choose: memorable, suitable TLD, legal availability. Shopify: Settings > Domains, DNS, primary domain, SSL. Renew, secure access, one canonical version.

FAQ
Do I need a .com or .fr domain for Shopify?
No technical obligation. The .fr provides reassurance in France; the .com is suitable internationally. Choose according to your main market and the availability of the name.
Can you sell without a custom domain on Shopify?
Yes, temporarily via yourstore.myshopify.com, but for a professional image and long-term SEO, connect a custom domain before the public launch.
How much does a domain name cost?
Order of magnitude: €10 to €20/year for a standard .fr or .com (rates vary depending on the registrar and extension). Shopify also offers direct purchase with annual renewal.
Changing domain: SEO impact?
A change without 301 redirects to the new domain can cause a loss of traffic and signals. Plan the migration, Search Console setup, and updates of external links.
