Want to buy a domain for your business but don't know where to start? This comprehensive guide reveals the essential aspects of domain selection, extensions, and subdomains that will define your online presence.

Want to buy a web domain for yourself or your business but don't know where to start? Choosing the right domain is one of the most critical decisions you'll make for your online presence. A well-chosen domain can establish instant credibility, improve your search rankings, and become a valuable digital asset for years to come.

In this comprehensive guide, you'll discover the essential aspects of web domains that every business owner and entrepreneur must understand. From the fundamental structure to advanced strategies for securing your perfect domain, we'll cover everything you need to make an informed decision.

By the end of this article, you'll have a clear understanding of how domains work, which extension suits your needs, and the proven strategies to avoid costly mistakes when purchasing your domain.

What is a Web Domain?

Many people don't know what a web domain actually is, and to understand it fully, you need to know its structure.

A web domain is the unique name that identifies a space on the internet. Think of it like a passport for websites. Just as people have unique identification documents to differentiate themselves from others, websites need unique domains to be found and recognized online.

Imagine the internet as a massive city with millions of buildings. Your domain is essentially your street address. Without it, visitors would have no way to find your specific location among the countless other sites.

Why Your Domain Matters

Your domain is often the first impression potential customers have of your brand. Consider these statistics:

  • 75% of users judge a company's credibility based on their website design and domain
  • Memorable domains can increase direct traffic by up to 50%
  • The right domain can significantly impact your email deliverability and professional perception

A domain isn't just a technical necessity. It's a strategic business asset that communicates professionalism, trustworthiness, and brand identity.

Domain Structure Explained

Understanding domain structure is fundamental before making any purchase decision. A domain is composed mainly of two parts: (1) the domain name and (2) the domain extension, and together they represent your web's unique identification.

Think of it like a person's full name and country of residence. The domain name is your unique identifier, while the extension provides context about what type of organization you are or where you're located.

Breaking Down a Domain

Let's examine a practical example:

www.alkitu.com

  • Subdomain: "www"
  • Domain Name: "alkitu"
  • Extension: ".com"
  • Complete Domain: "alkitu.com"

The combination of the domain name and extension creates what we call the fully qualified domain name (FQDN). This is what you'll purchase and what users will type to reach your website.

Additionally, domains usually come accompanied by a subdomain, which we'll explain in detail later in this guide.

Domain Names and Extensions

Domain names are completely free to choose, although they have certain limitations. Remember that several people can have the same "domain name" or the same "domain extension," but never the same complete domain.

Domain Name Rules and Limitations

When choosing your domain name, keep these essential characteristics in mind:

  • Characters allowed: Letters (A-Z) and numbers (0-9)
  • Special characters: Some extensions allow diacritical marks (like n with tilde)
  • No spaces: Use hyphens (-) as separators instead
  • Starting character: Must begin with a letter or number
  • Length limits: Minimum 2 characters, maximum 63 characters
  • Case insensitive: "ALKITU.com" and "alkitu.com" are identical

Understanding Domain Extensions

The domain name must be followed by an extension. Unlike domain names, extensions cannot be freely created. You must choose from an existing list of registered top-level domains (TLDs).

The most popular extensions include:

  • .com - Commercial (most recognized globally)
  • .net - Network (originally for internet companies)
  • .org - Organization (typically non-profits)
  • .co - Company (popular alternative to .com)

Over time, hundreds of new extensions have been created, including ".xyz" by Google and specialized ones like ".agency," ".app," ".auto," and many more.

Choosing the Right Extension

Despite the vast variety of available extensions, developers and marketers prefer the most popular options because they generate more trust among users.

Generic Top-Level Domains (gTLDs)

These are the most versatile and globally recognized:

  • .com - Any commercial business (Highest trust level)
  • .net - Tech companies, networks (High trust level)
  • .org - Non-profits, communities (High trust level)
  • .edu - Educational institutions (Very high trust level)
  • .gov - Government agencies (Very high trust level)
  • .agency - Agencies, consultants (Medium trust level)
  • .app - Mobile applications (Medium trust level)
  • .site - General websites (Medium trust level)
  • .global - International businesses (Medium trust level)

Country Code Top-Level Domains (ccTLDs)

These indicate geographical location and can build local trust:

  • .es - Spain
  • .ie - Ireland
  • .it - Italy
  • .ca - Canada
  • .ve - Venezuela
  • .co - Colombia
  • .us - United States
  • .uk - United Kingdom
  • .de - Germany
  • .fr - France

Multinational Company Strategy

You'll notice that different multinational companies often have multiple domains, each corresponding to countries where they have branches or significant markets.

Example: Coca-Cola's Domain Strategy

  • Main: www.coca-cola.com
  • Ireland: www.coca-cola.ie
  • Italy: www.coca-cola.it
  • Canada: www.coca-cola.ca

One of the biggest challenges companies face is reserving extensions in time. If someone buys a domain before you, they have the right to keep it until they stop paying the annual fee.

The Domain Squatting Problem

It can happen that when searching for the domain you want for your website, you find it's already occupied even though it's not being used. If you still want to buy it, you might discover it could cost hundreds or thousands of euros when it usually costs between 8 to 12 euros per year.

There are people who dedicate themselves exclusively to buying promising domains to resell them later at inflated prices. This practice, known as domain squatting, can be frustrating for businesses trying to establish their online presence.

Alternative Strategies When Your Domain is Taken

Perhaps you already have a business and when creating your website you discover that the domain is already in use by another person. In these cases, the best solutions are:

  1. Buy an alternative extension: If "mybusiness.com" is taken, try "mybusiness.net" or "mybusiness.co"
  2. Add a complementary word: Consider "getmybusiness.com" or "mybusinesshq.com"
  3. Use your location: Try "mybusinessnyc.com" or "mybusinessusa.com"
  4. Negotiate purchase: Contact the current owner (be prepared for premium prices)

Understanding Subdomains

The subdomain is found before the domain name. The most common and well-known by the vast majority of people is "www".

What You Need to Know About Subdomains

First, you should know that by default, subdomains are included with the purchase of your domain. Hosting companies usually specify how many subdomains you can have with your domain purchase, and "www" always comes included by default.

Strategic Uses for Subdomains

Subdomains are particularly useful if you have an online business with different categories or sections and want to make this difference noticeable on your website.

Here are real-world examples of how major companies use subdomains:

  1. Blog Section: Twitter has a completely different subdomain and style for its blog (blog.twitter.com)
  2. E-commerce: Many companies use "shop" for their online store section
  3. Regional Targeting: Some use city or country names to redirect visitors to local branches
  4. Support Portals: "support.company.com" or "help.company.com"
  5. Developer Resources: "developers.company.com" or "api.company.com"

Subdomain Characteristics

  • Position: Located before the domain name
  • Characters allowed: Letters with and without diacritical marks (A-Z, n with tilde, etc.) and numbers (0-9)
  • No spaces: Use hyphens (-) as separators
  • Starting character: Must begin with a letter or number
  • Maximum length: 63 characters per subdomain level

Practical Subdomain Examples

For a domain like alkitu.com, you could create:

  • www.alkitu.com (default)
  • blog.alkitu.com (blog content)
  • community.alkitu.com (user forums)
  • shop.alkitu.com (e-commerce)
  • valencia.alkitu.com (regional office)
  • your_company.alkitu.com (client portals)

Essential Buying Tips

Now that you understand domain fundamentals, here are proven strategies for making your purchase:

1. Act Fast on Your Preferred Domain

If you find a domain you love that's available, don't wait. Domain availability changes constantly, and the perfect domain could be gone tomorrow.

2. Consider Long-Term Investment

While domains typically cost 8-12 euros per year, consider registering for multiple years if you're confident in your choice. Many registrars offer discounts for longer registration periods.

3. Protect Your Brand

If budget allows, consider purchasing multiple extensions of your domain name:

  • Primary: mybusiness.com
  • Backup: mybusiness.net, mybusiness.org
  • Local: mybusiness.es, mybusiness.co.uk

This prevents competitors or squatters from acquiring similar domains.

4. Choose a Reputable Registrar

Popular domain registrars include:

  • GoDaddy - Largest selection, frequent promotions
  • Namecheap - Competitive pricing, good support
  • Google Domains - Simple interface, transparent pricing
  • Cloudflare - At-cost pricing, included security features

5. Enable Domain Privacy

Most registrars offer WHOIS privacy protection. This prevents your personal information (name, address, phone) from being publicly visible in domain registration records.

Mistakes to Avoid

Learning from others' mistakes can save you time, money, and frustration:

1. Choosing an Overly Complex Domain

Avoid:

  • Long, hard-to-remember names
  • Multiple hyphens (my-super-long-business-name.com)
  • Numbers that could be confused (is it "5" or "five"?)
  • Unusual spellings that require explanation

2. Ignoring Trademark Issues

Before finalizing your domain, research trademark databases to ensure you're not infringing on existing intellectual property. This could lead to costly legal battles.

3. Forgetting to Renew

Set up auto-renewal for your domain. Many businesses have lost their domains simply because they forgot to renew, and domains can be purchased by others within hours of expiration.

4. Overlooking Email Considerations

Remember that your domain will also be used for professional email (you@yourdomain.com). Consider how the domain looks and sounds when spoken aloud in email addresses.

5. Not Planning for Growth

Choose a domain that can scale with your business. Avoid overly specific geographic or product names if you plan to expand in the future.
