Long Domain Names: What Alphabet’s abcdefghijklmnopqrstuvwxyz.com Teaches Us (2026)

In October 2015, days after Google reorganised itself under a new parent company called Alphabet, the company registered one of the internet’s most playful addresses: abcdefghijklmnopqrstuvwxyz.com, the whole alphabet as a domain. It made headlines, but it also raises a question every site owner faces: are long domain names a good idea? Here is what Alphabet did, and what it teaches about choosing and protecting a domain in 2026.

Quick answer: Long domain names are usually a bad choice for your main website because they are hard to remember, type and say out loud. Alphabet used the short abc.xyz as its real website and registered abcdefghijklmnopqrstuvwxyz.com mainly as a novelty and to protect its brand. For your own site, pick a short, easy-to-spell name and register a few close variations so nobody else can grab them.

Why Alphabet registered the whole alphabet

Alphabet’s corporate website was, and still is, abc.xyz (external site). The obvious address, Alphabet.com, belonged to BMW’s fleet-leasing business, which had no reason to sell it. So Alphabet went short and quirky with abc.xyz, and also registered the 26-letter .com, most likely to stop cybersquatters and for a bit of fun. Big brands own thousands of defensive domains for the same reason. Around the same time, an ex-Googler even managed to buy Google.com for $12 for a minute before Google cancelled the sale.

Long domain names: pros and cons

Pros

• Easy to find available: most short .com names are taken, long ones usually aren’t.
• Can describe exactly what you do, such as a city plus a service.
• Memorable as a gimmick, if the long name is itself the joke.

Cons

• Hard to remember and easy to mistype, which sends visitors to the wrong site.
• Awkward to say on a podcast, video or phone call.
• Long email addresses and cut-off links in social posts and print.
• Keyword-stuffed names look spammy and give no ranking advantage in Google today.

Other famous long domain names

Alphabet was not the first to play with length. A Welsh village with a 58-letter name, Llanfairpwllgwyngyll, has used its full name as a .co.uk address for years, and several novelty sites have competed for the “longest domain name in the world” title using the full 63 characters. They get attention and the occasional news story, but almost no one types them in, which is exactly why businesses keep their main address short and point the long one at it.

How to choose a domain name in 2026

1. Keep it short: ideally under 15 characters, with no hyphens or numbers.
2. Make it easy to spell: if you have to spell it out loud, it’s too hard.
3. Choose a brandable name rather than a string of keywords.
4. Try other extensions if the .com is taken: .co, .io, .ai or newer ones like .xyz from the XYZ registry (external site), which Alphabet used. Country extensions such as .in work well for local audiences.
5. Register close variations: common misspellings and other extensions, so others can’t cybersquat your brand. We did this ourselves when we picked up quickonline.tips.
6. Lock it down: turn on auto-renew, registrar lock and two-factor sign-in. See our guide to domain name security.
