Domain Name

What is a domain name?

A domain name is the address people type into their browser to reach your website. For example, convertilab.fr is a domain name. It has two parts: the name (convertilab) and the extension (.fr, .com, .net, .org and so on). Technically, a domain name is a friendly alias for an IP address (for example 185.199.108.153): nobody would remember a string of numbers.

Your domain name is your permanent address on the internet. It is the basis of your online identity, your professional credibility and your search strategy.

How to choose a good domain name

Simplicity is the golden rule. Your domain name should be short (ideally 6 to 14 characters), easy to remember, easy to spell (avoid hyphens, numbers and doubled letters) and easy to say out loud (the phone test: if you have to spell it over the phone, it is too complicated).

The extension should match your geographic target. .fr is preferred for a French audience, because it inspires local trust. .com is universal and ideal for an international audience. The newer extensions (.tech, .shop, .agency) are available but less familiar to the general public. At a minimum, register both the .fr and the .com to protect your brand.

How it relates to your brand is essential. Ideally, your domain name is your company name: brand.fr. If the exact name is not available, avoid convoluted variants (my-brand-paris-2024.fr) and consider changing the name or buying the domain instead.

How a domain name affects SEO

A domain name influences SEO in several ways. Domain age is a factor: a domain registered 10 years ago inspires more trust in Google than one registered a month ago. Domain history counts too: a domain that hosted spam in the past can carry a bad reputation, so check archive.org before buying an expired domain.

The .fr extension gives a slight advantage for ranking in France, as a geographic signal. An EMD (Exact Match Domain) such as "plombier-lyon.fr" carried a significant SEO advantage before 2012, but Google has reduced that bonus. In 2026, a strong brand name beats a generic EMD.

The HTTPS protocol (an SSL certificate) is mandatory. Google penalises sites served over HTTP and browsers display a "Not secure" warning. Most hosts include a free SSL certificate (Let's Encrypt).

Managing and protecting your domain

Renew your domain before it expires. An expired domain goes back on sale and can be snapped up by a competitor or a cybersquatter. Turn on automatic renewal and register your domain for 3 to 5 years at least.

Protect your brand by registering the main variants: .fr, .com, and possibly common misspellings. Whois privacy hides your personal details from the public domain directory.

Never hand ownership of your domain to your web provider. The domain should be registered in your company's name, in your own account with a registrar (OVH, Gandi, Cloudflare, Namecheap). Plenty of businesses discover they do not own their domain only when they change provider.

Where to buy a domain name

The main registrars in France are OVH (the cheapest, from 6€ a year for a .fr), Gandi (known for its support), Cloudflare (at cost, with no margin) and Namecheap (international). Prices range from 6€ to 15€ a year for a standard .fr or .com. Premium domains (short, generic) can cost thousands of euros.

DNS records: how they work

Owning a domain is not enough: you also have to configure it through its DNS records, which tell the internet where each service lives. The most common are the A record (points the domain to a server's IP address), the CNAME (points a subdomain at another domain, for example www at your host), MX records (send your email to your mail provider), and TXT records (used in particular for email authentication with SPF, DKIM and DMARC).

A classic mistake is changing an A record without understanding DNS propagation: any change takes anywhere from a few minutes to 48 hours to spread across the whole internet. So do not panic if your site is not reachable straight after a change.

Common mistakes with domain names

Some mistakes cost business owners dearly:

- Leaving the domain in the provider's name, which makes changing agency difficult or even impossible. - Forgetting to renew and losing the domain to a competitor or a reseller. - Choosing a name that is too long or complicated and that customers mangle over the phone. - Not registering the variants (the .com as well as the .fr), leaving the door open to confusion. - Buying an expired domain without checking its past, and inheriting a damaged SEO reputation. - Turning off whois privacy, which exposes your personal details to cold calling and spam.

Checklist to secure your domain name

To sleep soundly, follow these practices:

- Register the domain in your company's name, in your own registrar account. - Turn on automatic renewal and register for 3 to 5 years. - Register at least the .fr and the .com of your brand. - Turn on whois privacy to protect your data. - Turn on two factor authentication on your registrar account. - Check at regular intervals that your SSL certificate is still valid. - Keep your registrar login details somewhere safe.

A telling example: a company that protects its domain from day one spends around 24€ a year for the .fr and the .com. Recovering a lost domain, or buying back a variant held by someone else, can cost several thousand euros and months of paperwork. Prevention is incomparably cheaper than repair.

Your domain name is your permanent address on the internet and the pillar of your online identity.
