A short history
The word boo has been used in English for a long time, especially in stories, games and parties where someone jumps out to surprise the group. The .boo extension is a generic ending, so it says nothing about a country. Because the word is short and light in tone, it fits sites about entertainment and seasonal celebrations, where a cheerful address is part of the fun.
Who runs it
The registry behind the zone publishes the rules for registering names, and registrars sell those names to the public. Rules for generic zones can be updated, so read the policy that is in force on the day you order. Details about the zone's management can change over time, so use the current information from the registrar rather than an older guide.
Rules in practice
- Open registration: names in generic zones are usually open to individuals and businesses, under the policy in force.
- Content: the policy may limit certain material, so keep the site within the rules and within the law.
- Characters: letters, digits and hyphens are allowed, with up to 63 characters in a single label.
- Renewal: set a reminder well before expiry, since an event site that lapses can leave guests with broken links.
Who uses .boo
- Halloween shops, costume makers and party suppliers.
- Game developers and small studios that publish short games and demos.
- Event organisers who run haunted houses, quiz nights or family fairs.
- Bloggers and fans who write about horror films, ghost stories and folklore.
Strengths
- The word is short, memorable and easy to say, which helps it travel by word of mouth.
- It sets a light and friendly tone straight away, which suits family and entertainment projects.
- It works well on posters, tickets and stickers for events.
Things to keep in mind
- The ending is playful, so it is less suited to a serious financial or legal service.
- Some visitors may not know the word or may read it as a joke, so explain the purpose of the site on the front page.
- Seasonal projects need planning, because traffic may peak over a few weeks and then fall away.
- Visitors may still type .com first, so decide whether you also want that address.
Tips before you register
- Check the name in .com and on the game stores, social platforms and event listings you plan to use.
- Make sure the content matches the age guidance on your product or event.
- Publish a privacy notice if you collect player or guest details, such as e-mail addresses for tickets.
- Set up SPF, DKIM and DMARC records before you send ticket or order e-mails.
- Protect the registrar account with two-factor login so that nobody else can change your event page.
