Domain Buying Guides

When you buy a domain name, you purchase a piece of digital real estate. But what, exactly, are you getting for your money? NameExperts.com Director Joe Uddeme unravels the elements of a domain name – so you’ll have a clearer understanding of the architecture behind them.

 

A domain name is an address you type into your web browser whenever you want to visit a website. It is arguably one of the most important assets any business can own.

While ‘domain name’ is an all-encompassing term, a domain is actually made up of multiple parts. Understanding these elements can give you a clearer picture of the domain name investing world and ensure you’re well-informed before buying a domain name or asking a skilled domain broker to negotiate the purchase of one on your behalf.

What are domains?

A domain name is a human-readable address that directs you to a particular website available on the internet. It’s akin to the address for your official residence or workplace. When someone wants to visit you, they come to your address. Similarly, when someone wants to visit a website, they type in the domain address in their web browser.

Any domain name has four main components;

  1. Domain name: The name of the domain itself.
  2. Top-Level domain (TLD): The suffix that appears after the domain name, e.g., .COM and .NET.
  3. Subdomain: A domain that is part of another primary domain. It is also known as a third-level domain.
  4. Protocol: The system that specifies how information from the domain is transferred to your web browser. It is either HTTP (insecure) or HTTPS (secure).

Take https://www.nameexperts.com/, for example.

  • NameExperts is the domain name
  • .COM is the top-level domain
  • WWW is the subdomain
  • HTTPS is the protocol

The 3 Types of Domain Names

There are three main types of domains, including:

1. Top-Level Domains

A top-level domain (TLD) is the final section of a domain name. It is the last segment of text appearing after the dot symbol. For example, in Google.com, .COM is the top-level domain.

Ever since the world wide web’s inception, .COM has been the most common top-level domain. It was originally used to designate commercial businesses but has become the de-facto TLD for most websites.

Another popular TLD is .NET. It was initially meant for internet service providers and networks but is now available to anyone who wants it. Because NET signifies network and technology, this is an ideal option for technology companies.

Yet another well-known TLD is .ORG, which was originally used to designate not-for-profit organizations. Till today, most people associate this TLD with non-profit organizations and social causes rather than commercial businesses. The .ai TLD is another popular one today – especially for tech firms.

There are two main types of top-level domains;

Generic TLD

A generic top-level domain refers to domain name endings with three or more characters, the type that you’d most likely recognize. .COM, .NET, .ORG, .INFO, and other common domain endings fall under this category.

Before 2011, there were barely two dozen domain extensions classified as generic. That year, the Internet Corporation for Assigned Names and Numbers (ICANN) expanded the number of generic domain extensions from 22 to over 1,200, opening up more opportunities for individuals and businesses to acquire domain names.

Country-Code TLD

As the name implies, these are domain extensions associated with specific countries. ICANN assigns country domain endings to each formally recognized nation and sovereign state, and these nations collect a royalty on every sale of their assigned TLD. For example, Tuvalu, a small island nation, earns 1/12th of its annual income from its .TV domain extension.

Other popular examples of country domain endings include

  • .US for the United States of America
  • .AU for Australia
  • .DE for Germany
  • .CA for Canada
  • .CC for Cocos Islands
  • .AE for the United Arab Emirates (UAE), etc.

2. Second-Level Domains

A second-level domain is directly below a top-level domain in the domain hierarchy. It is the part of the domain name that comes right before the top-level domain. For example, in NameExperts.com, NameExperts is the second-level domain.

The second-level domain is usually a combination of words describing the business or service of the domain name owner – and it pays to match this to the name of your business whenever possible to strengthen your brand. In the above example, NameExperts describes the business of a professional domain name broker that helps customers to acquire valuable domains.

A second-level domain can include letters, numbers, and hyphens. Symbols are not allowed.

3. Third-Level Domains

The third-level domain, or subdomain, is the part of the URL that comes before the second-level domain. The most common subdomain is www., which refers to the world wide web. Third-level domains are not mandatory, so you can have a fully functional domain name without the www part.

Some website owners create third-level domains to represent a different section of their website. Examples include:

  • Shop.mywebsite.com refers to the e-commerce section of a website.
  • Blog.mywebsite.com refers to a blog attached to the website.
  • Support.mywebsite.com leads to the customer support section of a website.

Understanding Domain TLDs

A domain name is the most important property for anyone who conducts business online. Hence, it’s crucial to understand what they are and the different types of domain name extensions to use for a website.

The information above should help you figure out how to structure your domain, but if you need help, we’re experts at domain selection and helping you buy the perfect domain.

Biggest Trends That Will Help You Buy Premium Domain Names In 2025

Looking to buy domain names in 2025? Here’s Name Experts Director Joe Uddeme with a roundup of emerging trends and things to look for when adding a name or two to your portfolio.   Buying the right domain is crucial for a successful business, which is why our professional team at NameExperts.com makes sure to stay on top of emerging trends. What was right for your business a decade ago – probably your brand name + .com – might still be relevant today, but there are newer alternatives and domain name combinations that consumers are comfortable with, too. Purchasing premium domain names is a great idea for any emerging business that wants to scale their brand. Top companies around the world are teaming up with domain brokers to help them buy premium domain names at the best prices – and with their anonymity preserved if necessary, too. Save money, add credibility, and give your company equity value when you work with experts like us. Key Takeaways GDPR has changed the rulebook There are now more TLDs (.com, .ai, .io, etc.) than ever – but not all are popular Catchy ‘meaningless’ names can become very valuable   Trend #1: Easier Identity Protection Have you heard of GDPR? When it comes to identity and privacy online, it can be very difficult to identify actual ownership of domains – which is why we recommend working with a top domain broker who has the skills to properly identify owners and help you navigate the domain world. The General Data Protection Regulation, or GDPR, is a new and strict set of rules and regulations that mandate how businesses that gather customer data and also how they must protect that data. It also outlines severe penalties for companies that violate the GDPR. This can make it that much more challenging to identify who owns what. No matter the size of your company, if you’re doing business in Europe, you should be thinking about how you’re protecting your employees’ and clients’ information online.   Trend #2: Reduction In GTLD Registrations TLDs are the letters found at the end of an internet address, such as .com, .net or .org. Any TLD that isn’t representing a country or territory is known as a generic top-level domain. The New gTLD Program was an initiative coordinated by the Internet Corporation for Assigned Names and Numbers (ICANN), which has increased the domain name system. With the introduction of new top-level domains, it was meant to enhance competition and consumer choice when it comes to domain names. It also brought many new safeguards to help support a secure, stable and resilient internet. Though there is a rise in new generic top-level domains or gTLD registrations, the trend is that many registrations are not being renewed – meaning there is limited value in this type of asset. There are so many different domain identifiers, like .law, .brand, .legal that it is easy to get carried away. We believe these new registrations will continue to decline and buyers will focus much more on sensible and dependable options such as .com, .co, .net, and .org. However, there are several newer options that can be worth investigating. These include .ai domain names and also .io, which are beloved of tech brands.   Trend #3: Interesting Combinations and Lateral Thinking Verbs and action phrases at the start of a domain name are in vogue. Things like ‘get’ or ‘try’ – resulting in www.getselfhelp.co.uk, for example. Thinking laterally also leads to the likes of Zyro and Figma, which have become highly-prized brands based around words that didn’t exist. We regularly help clients to align themselves with strong and/or catchy names that appear to be unavailable. It’s one of the many reasons that people turn to a domain broker. As well as helping you to choose a strong brand name that has long-term value, we bring expert negotiation skills to the table. We also take care of every element of the transaction – from soup to nuts. Our team offers a full-service domain name brokerage experience for each one of our clients. It’s our mission to protect our clients’ anonymity and deliver great results. From domain name acquisition to the divestment process, we have the knowledge you need to help you grow your business and protect your assets.   About the author Joe Uddeme is Director and Principal of Name Experts, one of the world’s leading domain name brokerage services.

How Much Do Domain Names Cost? Everything You Need To Know

Ready to start a business? Then get set to enter the world of domain name buying. In this post, NameExperts.com Director Joe Uddeme covers all the pricing information a newcomer to domain names needs to know.   When it’s time to start your business online, securing a domain name is the first step. Regardless of whether or not your business is established, you can’t create a website without a domain name. If you’re like most business owners, you’re probably wondering how much do domain names cost? You might also have questions about how much time you should spend looking for the right URL or even how to buy a domain name. We’ve got the inside scoop on what you need to know. Your domain name essentially functions as your website’s address, so you want to make sure you have one that is simple and relevant. You’ll also want to make sure it’s easy to remember so that people can easily find you and your business online. With all of that in mind, it’s easy to see why some people are willing to break the bank to get the domain name they want. If your domain name is just right, it can greatly increase website traffic. Discover everything you need to know about domain names and how much they cost right here. Key Takeaways A beginner’s guide to domain names Pricing details for domain name buyers How a domain broker can secure a better price and streamline the process   Pricing for Domain Names – the Inside Guide Ready to delve into domain names and what they cost? Let’s start with the basics: What Is A Domain Name You don’t want to shell out a ton of money on a domain name without first understanding what you’re paying for. We mentioned it earlier, but a domain name is the web address you type into a browser to bring up your specific website. It typically will start with https or www and will end with something common like .com. You’ll recognize some of the higher profile (read: high traffic volume) domain names like www.google.com or www.irs.com. Why Do You Need To Purchase One If you want to have a website, then registering your domain is absolutely necessary. There are three main reasons why you might need to buy a domain. 1. You’re building a website. You’ll most likely use a domain name that ties in with your business name or utilizes keywords that are related to your company. This is a non-negotiable part of the business world – you need a domain name. 2. Another reason you might register a domain name is when you’re considering starting a business or website. If you have a great idea for a business or a website, then you might want to jump on registering the domain you want. Stake your claim before anyone else comes along and takes it before you’re ready to execute. Check out our guide to finding a great brand name for your business. 3. The third reason that people start to wonder how much domain names cost and start registering domain names is when they are investing. Domain name investing was really popular at the start of the internet age, when popular keywords were still available. Nowadays, a lot of domain names are already taken (read: what to do if the domain you want is taken), but domain investing can still be a great way to earn money. If you’re working with a broker who is managing your domain portfolio, you can find domains that have the potential for significant value and buy them now so that you can sell them for a profit later. How Much Do Domain Names Cost In general, you can purchase a domain name for $2-$20 a year, depending on discounts available and who you’re purchasing it from. Newer domain extensions, the part at the end of your address, like .app or .info might cost more, as they are newer on the market. We can break down how much domain names cost based on a couple of factors. Like we just said, the domain extension can increase the price – for example, using .com might be more expensive than .shop. Where you purchase your domain name is another factor. A reputable registrar might be less expensive than an aftermarket service or private seller. Additionally, if you choose to register for multiple years and elect to include domain privacy it can also increase or decrease the price of your domain name. You’ll find that the most expensive domain names will be the ones you’ll find on auction houses, through private sellers, or aftermarket services. Unfortunately, there are no hard or definitive prices for domain names, regardless of the avenue you choose to purchase from. The domain name industry varies, just like real estate. Sometimes it’s a seller’s market, sometimes it’s a buyer’s market – as our guide to domain name valuation illustrates. Scarcity, though, is what drives domain name prices to eye-watering levels. Add in desirabilty, and you have a recipe for domain name costs that can shoot through the roof. The most expensive domain name ever sold – cars.com – went for just a little short of a billion dollars. Make sure you consult a domain broker if you’re looking to buy from a private seller, or are looking to purchase a domain that is already owned. Brokers are experienced and can handle all of the ins and outs of the acquisition and negotiation process so that you get the domain you deserve at a fair price. Why You Should Consider Hiring A Broker As mentioned above, hiring an experienced domain broker might be the best idea to make sure you get the domain you want. However, for a readily-available name, such as parkmylimo.com, there’s no need – it’s yours from any of the registration companies for just a few dollars. If you can be flexible when the domain you want isn’t available, that’s another great way to snap up a bargain, too. Sometimes, though, you can’t proceed without a certain domain name. Even the mighty Tesla struggled to do what they wanted with the brand because they didn’t own tesla.com. They eventually bought it – after many years of negotiations and a price tag thought to be in the many millions. A broker with experience will know the market inside out. He or she will have a thick contact book, and their years of experience provide leverage when negotiating the best price for you. If going it alone, look out for hidden fees, discount scams, and even hidden costs in your written agreements. This is where having a domain broker on your side comes in handy. They know the lingo, they’ve negotiated before, and they aren’t emotionally invested, which means they just want to get you the best deal. Let a broker help you navigate this industry and help you determine what might be too good to be true. Sometimes, when a great domain seems really cheap, it might be because there are hidden fees when registering. A domain broker can help you choose a reputable registrar and find the right price.   About the author Joe Uddeme is Director and Principal of Name Experts, one of the world’s leading domain name brokerage services.

What is AI Domain – And Does the .ai TLD Work for Your Business?

Super-popular since the launch of chatGPT, .ai domain names are an attractive option for tech and machine learning businesses. Domain name expert Joe Uddeme explains the pros and cons.   The .ai domain extension is a top-level domain (TLD – check out our comprehensive guide to domain levels) that originated as the country code domain for Anguilla, a picturesque Caribbean island. Initially designated for local use, the .ai domain has since evolved far beyond its geographic roots. Today, it is recognized as a specialized domain extension tailored for companies involved in artificial intelligence and related technologies. The .ai domain stands as a beacon of innovation and technological prowess, particularly in the realms of artificial intelligence and technology. The .ai domain extension has become synonymous with cutting-edge advancements, making it a sought-after choice for businesses and organizations aiming to showcase their expertise in AI and related fields. In this post, we’ll look at the originals of the .ai TLD and discuss why it might be right for your business when you want to buy a premium domain name. Key Takeaways Origins of the .ai TLD What are the benefits of a sector-specific domain name? Popular .ai brands thriving today Is the .ai TLD safe?   Brief History of AI Domain The .ai domain has a fascinating history that dates back to 1995, when it was introduced as the country code top-level domain (ccTLD) for the island of Anguilla. Initially, the domain was restricted to businesses based in or tied to Anguilla, but in 2009, it was made available worldwide without restrictions. Since then, the .ai domain has gained popularity among tech companies and organizations globally, representing artificial intelligence and innovation. Today, the .ai domain is a sought-after domain extension, with many to establish a strong online presence.   AI Domain Names: Significance and Purpose AI domain names, which end with the .ai extension, are more than just web addresses—they are powerful tools for brand recognition and online presence. For tech companies and organizations, a .ai domain name signals a commitment to innovation and technological excellence. These domain names are particularly valuable for businesses in the AI sector, as they instantly convey a focus on artificial intelligence. By choosing a .ai domain, companies can create a unique and memorable web address that reflects their dedication to advancing technology and AI. This not only helps in establishing a strong online identity but also in attracting a tech-savvy audience. The concept of ‘ai domain growth’ is closely tied to the adoption and future prospects of .ai domains, driven by factors such as innovation in AI technologies, the number of AI-focused startups, and the consumer perception of .ai branding.   Benefits of .AI Domains SEO Benefits for AI-Related Topics One of the standout benefits of .ai domains is their potential to enhance search engine optimization (SEO) for AI-related content. Google treats certain country code top-level domains (ccTLDs), including .ai, similarly to generic top-level domains (gTLDs) like .com, .net, and .org. This means that a .ai domain can be just as effective in reaching users who are searching for AI-related information. By leveraging a .ai domain, businesses can improve their visibility in search engine results, thereby attracting more visitors interested in artificial intelligence. This SEO advantage, combined with the inherent brand recognition of the .ai extension, makes this kind of domain name branding a powerful asset for companies in the AI sector. Anyone involved in domain portfolio management today is quite likely to have one or more .ai domain names in their collection – if only for future-proofing reasons.   Popular AI Domain Examples The .ai domain extension has been embraced by numerous influential companies and organizations within the tech industry. Here are some notable examples that showcase the versatility and appeal of this domain extension: Open.ai Open.ai is a pioneering research organization dedicated to advancing artificial intelligence to benefit humanity. Their website, open.ai, serves as a hub for their groundbreaking work and mission in the AI field. By using the .ai domain extension, Open.ai underscores its commitment to innovation and leadership in artificial intelligence. Facebook.ai Facebook.ai is the dedicated platform for Facebook’s extensive research and development in artificial intelligence. The website provides a comprehensive overview of Facebook’s AI initiatives, including their cutting-edge AI-powered tools and technologies. The .ai domain extension helps Facebook highlight its focus on AI advancements and its role in shaping the future of technology. AI.google AI.google is Google’s showcase for its artificial intelligence research and development efforts. The website offers detailed information on Google’s AI projects, tools, and technologies, reflecting the company’s dedication to pushing the boundaries of what AI can achieve. The .ai domain extension reinforces Google’s position as a leader in the AI industry.   AI Domain vs Other Domain Extensions When it comes to choosing a domain extension, tech companies and organizations have several options, each with its unique advantages. The .ai domain stands out as a niche domain extension specifically associated with artificial intelligence and machine learning. While .com remains the most popular and widely recognized domain extension, .ai is rapidly gaining traction among businesses focused on cutting-edge technology. On the other hand, .io is another popular choice for tech companies, but it doesn’t carry the same strong association with AI as the .ai domain does. For businesses aiming to highlight their expertise in artificial intelligence, the .ai domain offers a distinct and memorable web address that sets them apart from the competition. (Need help securing a domain name that seems out of reach? Check out our guide to the top domain brokers for 2025). Comparison to .com Domain The .com domain is the most widely recognized and popular domain extension, with over 160 million registered domains. In contrast, the .ai domain has around 533,000 registered domains as of October 2024. While .com is a more established and traditional domain extension, .ai is gaining popularity as a niche domain extension for tech companies and organizations focused on artificial intelligence and machine learning. Google treats some ccTLDs, including .ai, .me, and .biz, the same way as .com, .net, and .org, making .ai a viable option for businesses looking to establish a strong online presence. Comparison to .io Domain The .io domain is a popular domain extension for tech companies, but it is not as closely associated with artificial intelligence as .ai. While .io is a more established domain extension, .ai is gaining traction as a niche domain extension for tech companies and organizations focused on artificial intelligence and machine learning. The .io domain has around 1.5 million registered domains, compared to the .ai domain’s 550,000. Why not check out our guide to choosing a domain name? It’s full of helpful tips and advice.   Acquiring and Configuring an AI Domain Acquiring and configuring a .ai domain is a straightforward process. To register a .ai domain, you can search for available domain names on a domain registrar’s website and proceed to check out. The registration process typically involves verifying the availability of the domain name, choosing your registration term, and paying the registration fee. Once the registration is complete, the domain name will be registered and available for use. To configure your .ai domain, you can set up website hosting, email hosting, and other services to establish a strong online presence. By securing a .ai domain, businesses can effectively signal their commitment to innovation and technological advancement in the AI industry.   AI Domain Safety and Security Features When it comes to online security, the .ai domain extension offers robust features to ensure a safe and reliable web presence. Here are some key safety and security measures associated with .ai domains: Overview of Safety Features Domain Name Dispute Resolution Policy: The .ai domain extension adheres to the Uniform Domain-Name Dispute-Resolution Policy (UDRP), providing a structured process for resolving disputes related to domain name registrations. This policy helps protect domain owners from potential conflicts and ensures fair resolution. Domain Name System Security Extensions (DNSSEC): The .ai domain extension supports DNSSEC, which adds an extra layer of security to domain name lookups. DNSSEC helps prevent certain types of cyber attacks, such as cache poisoning, by ensuring the authenticity of the DNS responses. Two-Factor Authentication: Many registrars offering .ai domain registrations provide two-factor authentication (2FA). This security feature requires users to verify their identity through an additional method, such as a mobile device, adding an extra layer of protection against unauthorized access. Domain Locking: Some registrars offer domain locking services, which prevent unauthorized changes to the domain name registration. This feature ensures that only authorized individuals can modify domain settings, reducing the risk of domain hijacking. WHOIS Protection: WHOIS protection services are available through some registrars, which hide the registrant’s contact information from public view. This feature helps protect domain owners’ privacy and reduces the risk of spam and identity theft. Overall, the .ai domain extension is a secure and reliable choice for businesses and organizations aiming to establish a strong online presence in the tech industry. With these comprehensive safety features, .ai domains provide peace of mind and robust protection against various online threats.   Who Uses .AI Domains? .ai domains are embraced by a diverse array of businesses and organizations within the AI and technology sectors. Here are some of the key users: Tech Companies: Many tech companies opt for .ai domains to establish a robust online presence and enhance brand recognition. The .ai extension underscores their commitment to technological innovation. AI Startups: For AI startups, a .ai domain is a perfect fit. It conveys a sense of cutting-edge technology and forward-thinking, which is crucial for attracting investors and customers.
