What Is a Domain Name?
A domain name is the address people type into their browser to
visit your website. Just like a physical address tells people where your house is, a domain name tells the
internet where your website lives. For example, ch7.co is a domain name.
Every website on the internet actually has a numerical IP address (like 192.168.1.1), but domain names exist because humans remember words much better than numbers. When you type a domain name into your browser, the internet's DNS (Domain Name System) translates it into the correct IP address and delivers the website to your screen.
Think of it this way: if your website is like a house, then the domain name is the street address, the hosting is the land the house sits on, and the website files are the house itself. You need all three — but the domain name is what people use to find you.
💡 Key Takeaway
Your domain name is your digital identity. It's the first thing people see, it becomes your brand, and it's nearly impossible to change once you've built traffic and reputation around it. Choose wisely from the start.
How Domain Names Work
Understanding how domain names work helps you make smarter decisions when buying one. Here's the simple breakdown:
📝 Domain Name Structure
Every domain has two main parts: the
Second-Level Domain (SLD) — the unique name you choose (like "ch7") — and the
Top-Level Domain (TLD) — the extension (like ".co" or ".com"). Together they form
your complete domain: yourname.com.
🌐 DNS — The Internet's Phone Book
When someone types your domain name, the browser contacts a DNS server which looks up which server (IP address) your website is stored on, then routes the visitor there. This process takes milliseconds and happens every time someone visits any website.
🏢 Domain Registrars
You buy domain names from domain registrars — companies authorized by ICANN (Internet Corporation for Assigned Names and Numbers) to sell domain names. Popular registrars include Dynadot, Namecheap, and Hostinger.
🔄 Registration & Renewal
You don't actually "buy" a domain — you lease it, typically in 1-year increments. You must renew it annually (or prepay for up to 10 years). If you stop renewing, the domain eventually becomes available for someone else to register.
How to Choose the Perfect Domain Name
Your domain name will define your brand for years to come. Here are the rules that separate great domains from forgettable ones:
The 7 Rules of a Great Domain Name
Keep It Short
Aim for 6–14 characters. Shorter names are easier to type, remember, and share. Compare "bestcheaphostingprovidersreviews.com" with "ch7.co" — shorter wins every time.
Make It Easy to Spell
If you have to spell it out loud, it's too complicated. Avoid unusual spellings, double letters, and words that people commonly misspell.
Avoid Hyphens and Numbers
Domains with hyphens or numbers look unprofessional and are harder to share verbally. "my-best-site-2026.com" is much worse than "mybrand.com".
Make It Brandable
A brandable name is unique, memorable, and evokes a feeling. "Google" didn't mean anything before the company existed. Think about creating a name that can grow with you rather than one locked to a specific product.
Consider Keywords (But Don't Overdo It)
Including a keyword can help with SEO — "hostingguide.com" tells Google what the site is about. But don't force it. Brand names perform better long-term than keyword-stuffed domains.
Check Social Media Availability
Before buying a domain, check if the matching usernames are available on Instagram, X (Twitter), YouTube, and TikTok. Consistent branding across platforms builds trust. Use tools like Namechk.com to check all platforms at once.
Check for Trademarks
Search the USPTO database (United States Patent and Trademark Office) and Google to make sure your desired name doesn't infringe on an existing trademark. This can save you from expensive legal issues later.
⚡ Pro Tip
Brainstorm 10–20 domain name ideas before checking availability. Many of your first choices will already be taken. Having a list prevents you from settling for a mediocre name out of frustration. Try combining words, using synonyms, or inventing portmanteau words.
Domain Extensions Explained (.com, .co, .io & More)
The domain extension (also called TLD — Top-Level Domain) is the part after the dot. Choosing the right extension shapes how people perceive your website.
| Extension | Best For | Price Range/Year | Trust Level |
|---|---|---|---|
| .com | General purpose, businesses, blogs | $8–$15 | ⭐⭐⭐⭐⭐ |
| .co | Startups, modern brands | $10–$30 | ⭐⭐⭐⭐ |
| .io | Tech companies, SaaS, startups | $30–$60 | ⭐⭐⭐⭐ |
| .net | Tech, networking, .com alternative | $10–$15 | ⭐⭐⭐ |
| .org | Non-profits, communities, open source | $10–$15 | ⭐⭐⭐⭐ |
| .store | E-commerce, online shops | $5–$20 | ⭐⭐⭐ |
| .blog | Bloggers, content creators | $5–$30 | ⭐⭐⭐ |
| Country TLDs (.uk, .de, .fr) | Country-specific businesses | $5–$20 | ⭐⭐⭐⭐ (locally) |
Our recommendation: Always try to get a .com first. It's the most trusted, most recognized, and easiest to remember. If your ideal .com is taken, .co is the best alternative for modern brands. For tech companies, .io is well-respected. Avoid obscure extensions like .xyz, .info, or .biz — they tend to look spammy.

Step-by-Step: Buy Your Domain Name
Here's exactly how to register your domain name, whether you're buying through Hostinger (with hosting) or Dynadot (domain only):
Option A: Buy Through Hostinger (Recommended)
Visit Hostinger and Choose a Hosting Plan
Go to Hostinger and select a hosting plan. The "Premium" plan ($2.99/month for 48 months) includes a free domain and is the best value for beginners.
Create Your Account
Sign up with your email address, Google account, or Facebook. Choose your payment period — longer plans have the biggest discounts.
Claim Your Free Domain
After purchasing, you'll be prompted to choose your free domain name. Search for your desired name — if it's available, claim it. Hostinger will automatically configure DNS, SSL, and nameservers for you.
Set Up Your Website
Your domain is now connected to your hosting. Install WordPress with one click, choose a theme, and start building your website.
Option B: Buy Through Dynadot (Domain Only)
Search for Your Domain on Dynadot
Go to Dynadot and use the domain search tool. Enter your desired name — Dynadot will show you availability across hundreds of extensions with pricing for each.
Add to Cart and Create an Account
Select the domain and extension you want, add it to your cart, and create a Dynadot account. You can register for 1–10 years at a time.
Enable WHOIS Privacy & Complete Payment
Dynadot includes free WHOIS privacy, which hides your personal information from public domain records. Complete your purchase via credit card, PayPal, or cryptocurrency.
Point DNS to Your Hosting Provider
If you have hosting elsewhere, go to your domain's DNS settings in Dynadot and update the nameservers to point to your hosting provider. Your host will provide the nameserver addresses (usually two addresses like ns1.hosting.com and ns2.hosting.com).
How to Protect Your Domain Name
Your domain name is a valuable digital asset. Here are the essential security measures every domain owner should enable:
🔒 WHOIS Privacy Protection
When you register a domain, your name, address, phone number, and email become publicly visible in the WHOIS database. Privacy protection replaces your details with the registrar's, shielding you from spam and identity theft. Both Dynadot and Hostinger offer this for free.
🛡️ Domain Lock (Transfer Lock)
Domain lock prevents anyone from transferring your domain to another registrar without your explicit approval. This is your first line of defense against domain hijacking. Always keep this enabled unless you're intentionally transferring.
🔑 Two-Factor Authentication (2FA)
Enable 2FA on your registrar account. Even if someone steals your password, they won't be able to access your account without the second verification step. Use an authenticator app (Google Authenticator or Authy) rather than SMS.
♻️ Auto-Renewal
One of the most common ways people lose domains is by forgetting to renew. Enable auto-renewal so your domain renews automatically before expiration. Keep your payment method updated so renewals don't fail.
⚠️ Warning: Domain Hijacking Is Real
Domain hijacking — where someone steals or takes control of your domain — happens more often than you'd think. High-profile cases have involved domains worth millions of dollars being stolen through social engineering or compromised email accounts. Protect yourself by using a strong, unique password, enabling 2FA, and locking your domain.
7 Common Domain Mistakes to Avoid
Learning from others' mistakes will save you time, money, and headaches:
Choosing a Name That's Too Long or Complex
Long domains get mistyped and forgotten. Stick to 2–3 words maximum. If you can't say it quickly in conversation, it's too long.
Ignoring Renewal Prices
Many registrars offer cheap first-year prices ($0.99–$1.99) but charge $15–$40/year for renewal. Always check the renewal price before buying. Dynadot and Hostinger offer transparent, consistent pricing.
Using an Obscure Extension
Extensions like .xyz, .info, .biz, and .click are associated with spam and low-quality sites. Stick with trusted extensions: .com, .co, .io, .net, or your country code.
Skipping WHOIS Privacy
Without privacy protection, your personal information is available to anyone in the world. You'll receive spam emails, robocalls, and even physical junk mail within days of registering.
Buying a Domain That Infringes Trademarks
Registering "nikedeals.com" or "applereviews.co" could lead to a legal dispute and losing the domain through a UDRP complaint. Always search the USPTO and WIPO databases before purchasing.
Not Registering Similar Variations
If your brand is "mybrand.com", consider also registering "mybrand.co" and "mybrand.net" to prevent competitors or squatters from using them. Redirect the extras to your main domain.
Letting Your Domain Expire
If your domain expires and someone else registers it, you may have to pay thousands of dollars to buy it back — or you lose it forever. Always enable auto-renewal and keep payment details current.
How Much Does a Domain Name Cost?
Domain pricing depends on the extension, the registrar, and whether the name is considered "premium." Here's a realistic cost breakdown:
| Cost Type | Price Range | Notes |
|---|---|---|
| Standard .com domain | $8–$15/year | Regular unregistered domains |
| Free with Hostinger hosting | $0 (first year) | Included in all hosting plans |
| Premium/short domains | $100–$50,000+ | Short, dictionary words, brandable names |
| WHOIS privacy | $0–$12/year | Free at Dynadot & Hostinger |
| Domain renewal | $10–$40/year | Check renewal price before buying |
💰 Best Value Option
The cheapest way to get a domain is bundled with hosting from Hostinger. For $2.99/month you get hosting + a free domain + free SSL + free email. That's your entire website foundation for about $36/year. See Hostinger pricing →
Frequently Asked Questions
How much does a domain name cost?
Domain names typically cost $7–$15 per year for popular extensions like .com. Hostinger includes a free domain with all hosting plans (from $2.99/month). Premium, short, or dictionary-word domains can cost hundreds to thousands of dollars on the aftermarket.
What is the best domain registrar for beginners?
Should I choose .com or another extension?
.com is still the most trusted and recognized extension. People instinctively type .com when looking for websites. If your ideal .com is taken, the best alternatives are .co (modern, short), .io (tech), .net (networking), or your country TLD (like .uk or .de for local businesses).
Can I buy a domain name without hosting?
Yes! You can register a domain independently from registrars like Dynadot or Namecheap without purchasing hosting. You can point the domain to a hosting provider later when you're ready. This is useful for reserving names or if you're not ready to build yet.
How do I protect my domain name?
Enable WHOIS privacy protection (hides your personal info), turn on domain lock (prevents unauthorized transfers), use a strong password with two-factor authentication on your registrar account, and set up auto-renewal so you never accidentally lose your domain.
What happens if I don't renew my domain?
After expiration, the domain enters a grace period (~30 days) where you can still renew at normal price. Then it enters a redemption period (30–90 days) with higher fees ($80–$200). Finally, it's released to the public and anyone can register it. Enable auto-renewal to avoid this entirely.
Conclusion: Get Your Domain Name Today
Buying a domain name is one of the simplest yet most impactful steps in starting your online presence. Your domain is your digital address, your brand identity, and the foundation of everything you'll build online.
