Choosing the domain name for your landing page: short, pronounceable, memorable

Before they even read your headline, visitors see one thing: the address. In the Google ad, in the link shared on a WhatsApp group, in the sender of the follow-up email. A good domain name can be retyped from memory after being heard once; a bad one gets lost between two hyphens and an ambiguous digit. The good news: the criteria that matter fit in a short list, and the main piece of received wisdom ("you need the keyword in the domain!") is outdated. Here is how to choose, check and buy yours — before connecting it to your page deployed on Vercel.

The criteria that actually matter

The phone test: can you dictate it without spelling it out?

The best filter is a single question: if you give the address to someone over the phone — or it's mentioned on a radio show, in a podcast, at the end of a webinar — can they retype it without you having to spell it? lumea.com passes the test; lume-a24.com fails it ("hyphen or no hyphen? the number in digits or in letters?"). This isn't just marketer's intuition: a study by Alter and Oppenheimer published in 2006 in PNAS ("Predicting short-term stock price fluctuations using processing fluency") showed that companies with easy-to-pronounce names — even easy-to-pronounce ticker symbols — outperformed hard-to-pronounce ones in the short term. How easily the brain reads and pronounces a name influences very real judgements and behaviours. For a landing page, the translation is direct: a fluent name gets remembered, shared and trusted; a laborious one creates friction before the first click.

Short, no hyphens, no ambiguous digits

• Short: aim for under 15 characters before the extension. Every extra character is one more chance for a typo, especially on a phone keyboard.
• No hyphens: said out loud, a hyphen forces you to add "with a hyphen" — and half your audience will forget it. The hyphen-free version almost always belongs to a third party or a competitor.
• No ambiguous digits: offer2024.com dictates poorly ("twenty-twenty-four, in digits"), and a number instantly dates the page.
• Easy to type on mobile: more than half your traffic will come from a phone; avoid tricky double letters and words that autocorrect insists on "fixing".
• No awkward homophones: say the name out loud to three people and ask them to write it down. If you get three spellings, change the name.

Which extension: .com, .fr or a new TLD?

For a French audience — LanderKit's home turf — the .fr remains the most reassuring choice: it signals an identifiable business, governed by AFNIC's rules, and it dictates naturally. The .com is the universal reflex — the extension people type by default when they can't remember — and the right pick if you're addressing an international audience or plan to. The ideal, when the budget allows (around €20 a year for both), is to buy both and redirect one to the other. The same logic applies country by country: a national extension reassures a local audience, .com covers everyone else.

What about the newer extensions — .io, .app, .club? They remain readable for a short-lived landing page or a tech-savvy audience, and often offer the short name that .com and national extensions no longer have available. Two caveats, though. First, trust: with a broad audience, an unfamiliar extension can cause hesitation, where .com and .fr go unnoticed. Second, the neighbourhood: a large-scale analysis of the new extensions presented by Halvorson and co-authors at the ACM Internet Measurement Conference in 2015 ("From .academy to .zone: An Analysis of the New TLD Land Rush") showed that a large share of registrations on these extensions were speculative or defensive rather than sites actually in use — which partly explains why some spam filters and some visitors treat them with caution. Also check, before buying, that professional emails sent from that extension won't land in spam.

Brand name or exact keyword?

The temptation is an old one: cram the target keyword into the domain (cheap-plumber-lyon.com) hoping for a boost in search results. That shortcut no longer works: Google confirmed long ago that an exact keyword in the domain no longer brings any decisive advantage, its algorithm having been adjusted to stop rewarding low-quality exact-match domains. What moves a landing page up the results is the content, the structure and the classic SEO signals — not three keywords strung together with hyphens. A short brand name, on the other hand, gets remembered, gets retyped as a direct search (a signal Google does observe) and leaves room to broaden the offer later without changing address. The simple rule: the keyword goes in the page's title and content, the brand goes in the domain.

One domain from the ad to the email

The most neglected criterion isn't in the name itself but in its consistency. If the ad shows myoffer.com, the click lands on promo-myoffer.site and the confirmation email is sent from contact@myoffer-mail.com, every break in the chain is an opportunity for distrust — it's exactly the pattern people have learned to associate with phishing. Align all three: the domain displayed in the ad, the domain of the page, and the sending domain of your emails. This matters all the more because a landing page often lives without a website around it: the domain is then the only marker of legitimacy the visitor can check.

Before you buy: the practical checklist

• Check social media availability: is the matching handle free on Instagram, LinkedIn, X? A domain whose namesake social account belongs to someone else creates lasting confusion.
• Check registered trademarks: in France, a free search of the INPI trademark database (or your country's equivalent) avoids pouring ad money into a name a third party could force you to abandon.
• Pay the normal price: a standard domain costs about €10–15 a year at a reputable registrar (OVH, Gandi, Cloudflare…). Beware of first years discounted to €1 with a €40 renewal.
• Turn on auto-renewal the day you buy, with a card that doesn't expire next month.
• Never let a domain with traffic expire: it would be snapped up within hours by speculators who inherit your residual traffic, incoming email and reputation.

What about a temporary campaign?

If the landing page supports a time-limited operation — a launch, a trade show, a seasonal offer — the real question isn't just the name, but the architecture: a dedicated campaign domain bought for the occasion, or a subdomain of your main site that inherits its trust and rankings? Both options have their case; we compare them in detail — SEO, tracking, cost — in our guide subdomain or dedicated domain for a landing page. The principle: a dedicated domain for what needs to live (or die) independently, the main domain for everything else.

Once the name is chosen and bought, the hard part is done — and the rest goes fast. A LanderKit template (€89 each, €229 for the full pack) goes live in about ten minutes following our Vercel deployment guide, and the custom domain is included in Vercel's free plan: two DNS records at your registrar, and your brand-new name points at a page built to convert.
