TL;DR: .io vs .com
.com is the more familiar option for most audiences and isn't tied to the status of any country or territory. .io is a country code domain that the tech world adopted as its own, so it signals startup energy and often gets you a shorter name.

What's the difference between .io and .com?
Both are top-level domains (TLDs), the part of a web address that comes after the dot. The real differences are in what they signal to visitors, how easy they are to get and what they cost to keep.
The extension doesn't change what your website can do. Speed, security and features like online selling depend on your hosting, software and setup, not on the letters after the dot.

What .com means
.com is short for "commercial" and was one of the original generic extensions created in 1985. It's one of the most widely used domain extensions and the one many people expect a business to have.
Anyone can register a .com, anywhere in the world. That openness is exactly why it's so crowded and why short, simple names are hard to find.
What .io means
.io is the country code domain for the British Indian Ocean Territory, a group of islands also known as the Chagos Archipelago. Tech founders picked it up because "I/O" is shorthand for input/output in computing.
Even though .io is technically a country code, Google treats it as a generic domain. It appears on Google's list of generic country code TLDs, so a .io site doesn't automatically target one country in search results.
.io vs .com at a glance
Here's a quick side-by-side look before we get into the details.
Factor | .com | .io |
Type | Generic TLD (gTLD) | Country code TLD (ccTLD) treated as generic by Google |
Often chosen by | Most businesses, ecommerce and local brands | Tech startups, SaaS and developer tools |
Recognition | Generally high with most audiences | Familiar in tech and less familiar to general audiences |
Availability | Short names are rarely available | Short names may be easier to find, although availability varies |
Approximate first-year price | About $10 to $25 | About $30 to $60 |
Approximate renewal | Similar to the first-year price | Often higher than the first-year price |
SEO impact | No automatic ranking advantage | No automatic ranking advantage |
Long-term status | Not tied to any country or territory | Active, with long-term status linked to an unresolved sovereignty question |
Prices are approximate standard rates and vary by registrar, promotion, registration term and premium status. Names bought on the aftermarket can cost far more.
.io vs .com compared
The table gives you the headline. Here's what each difference can mean in practice for your brand.
01. Trust and recognition
For many people, a .com simply feels familiar. That familiarity can help a new brand feel established sooner, especially with visitors who have never heard of it. A .io tends to carry credibility in tech circles, where it's widely associated with startup culture. Outside that world, recognition is generally lower, and some visitors may not know what the extension signals.
Expert tip from Scott Cohen, CEO of InboxArmy:
“While securing domains for InboxArmy, I never settled for clunky or forgettable options. A clean, professional URL radiates credibility, which is especially crucial to email marketing where trust determines whether messages land or die. I watch businesses cut corners with hyphenated domains or weird extensions, then scramble when they lose traffic to the obvious .com version.”
How much this matters depends on your market. Developers and B2B buyers often know .io well, while everyday consumers may be less familiar with it. Recognition can also vary by country and industry.
02. Availability and brandable names
Decades of registrations mean many short, catchy .com names are already taken or parked by investors. .io is less crowded, so short, brandable names may be easier to find, although availability varies and some desirable .io names are already registered too.
.io also allows clever domain hacks, where the extension completes a word. Think of a design studio on "stud.io" or a radio show on "rad.io".
Keep an eye out for premium domains in both extensions. Some sought-after names are classified as premium, so a domain that shows as available can cost much more than standard rates to register and sometimes to renew. Names resold on the aftermarket can cost thousands of dollars or more.
03. Price and renewal costs
Prices vary by registrar, promotion, registration term and premium status, so treat these figures as approximate examples. Across the market, standard .com registrations usually cost about $10 to $25 a year, with renewals in a similar range. Standard .io registrations often cost about $30 to $60 for the first year, and renewals are often higher.
On Wix, for example, .com starts at $7.90 for the first year and renews at $21.35, while .io starts at $34.90 (US prices checked in November 2026). Check the current registration and renewal rates on the domain pricing page before you buy, since prices can change.
Keep in mind that registering a domain gives you the right to use it for as long as you keep renewing it. If a renewal fails, the domain can expire and eventually become available to someone else.
04. SEO and search visibility
Google treats .io as a generic top-level domain, so it doesn't inherently target a particular country in search results. Neither .io nor .com receives an automatic ranking advantage based on the extension alone. Content relevance, site quality and other search signals matter far more.
Familiarity can still shape how people perceive a search result. That's a branding consideration more than a ranking factor, and with a tech audience a .io may feel just as natural as a .com.
05. Audience and brand perception
Your extension sends a signal before anyone reads a word on your site. Many people read a .com as established and mainstream, which suits ecommerce shops, local services and consumer brands. A .io tends to read as tech-forward and product-led, which is why it's popular with SaaS tools, developer platforms, AI and gaming projects.
If .io doesn't quite fit, other tech-friendly options include .ai, .co and .dev. Each one has its own vibe, so pick the one that matches what you build.
06. Typing habits and typo traffic
Many people type ".com" out of habit, and some phone keyboards even offer a .com shortcut. If you're on .io and someone else owns the matching .com, some of your visitors could land on their site instead. That risk grows with word of mouth, podcasts and anywhere people hear your name rather than click it.
The same goes for email. Customers who add .com to your address by mistake may send messages that never reach you.
07. Long-term stability and the future of .io
This is where .com has a clear edge. It isn't tied to the status of any country or territory, so it doesn't face the specific geopolitical uncertainty that affects .io.
The UK and Mauritius signed a treaty in May 2025 concerning the future sovereignty of the Chagos Archipelago, but the agreement's implementation remains unresolved. The UK legislation needed to implement it did not pass before Parliament's session ended in April 2026, and negotiations continued later that year.
That creates uncertainty around .io's long-term status because it's the country code domain for the British Indian Ocean Territory. However, .io remains an active country code domain, and a change in sovereignty would not automatically retire the extension. ICANN has said that any change to the .io code is not a foregone conclusion.
Retirement would only begin if IANA issued a formal notice of removal, which typically follows a change to the international list of country codes. Under IANA's retirement policy, a retiring country code normally gets a five-year transition period after that notice, with a possible extension of up to five more years. No such notice has been issued for .io.
For most businesses, the practical risk today is low. If you're building a brand for decades, owning the matching .com as a backup can be a smart safety net.
Which should you choose: .io or .com?
There's no universal winner here. The best extension is the one your audience recognizes and your budget can sustain year after year.
Expert tip from Inbal Geva, Product Lead and GM of Wix Domains:
"Everyone reaches for .com out of habit, but familiarity and performance aren't the same thing. In our data, extensions that clearly signal what a business does are associated with stronger results. If your ideal .com is already registered, you can usually get your exact brand under a more creative extension that fits. Consider a yoga studio on .yoga, a bar on .bar or a company on .co."
Choose .com if…
Pick .com if you sell to everyday consumers, run a local business or rely on word-of-mouth marketing. It's also a natural fit for ecommerce, where looking familiar at checkout can help.
If your ideal .com is taken, try adding a short word like "get", "try" or "hq" to your name before switching extensions. A .net can also work as a fallback, since it's widely recognized, although usually less familiar than .com.
Choose .io if…
Pick .io if you're building software, a developer tool or a tech startup and your audience already knows the extension. It's also a smart move when the .com you want is parked or priced out of reach.
Just plan for higher renewal costs and keep an eye on news about the Chagos Archipelago.

Consider registering both
Some brands register both versions of their name. You can build your site on one and use domain forwarding to send visitors from the other, so nobody gets lost.
This isn't necessary for every business. It makes the most sense when the matching domain is affordable, when customers are likely to type the other extension or when a lookalike site could confuse people. The protection only lasts while both registrations stay active, so renew them together.

How to register a .io or .com domain with Wix
Wix lets you search, register and manage your domain in the same place you build your site. As an ICANN-accredited registrar for over 400 extensions, including both .com and .io, Wix helps you grab one or both in a few minutes.
01. Search for your name
Type your brand name into the domain name search tool. It checks availability across hundreds of extensions and suggests alternatives if your first choice is taken.
02. Compare .com and .io prices
Check the first-year and renewal prices for each extension before you decide. Seeing both up front helps you plan for next year, not just today.
03. Choose your registration period
Register your domain for anywhere from 1 to 10 years, depending on the extension, and check the terms offered for .com and .io when you buy. A longer term means fewer renewal dates to manage. Turning on automatic renewal and keeping your payment details current also helps prevent your domain from expiring by accident.
04. Add the security options you need
Review the security and privacy settings for your new domain. You can add WHOIS privacy to help keep your contact details out of public registration records. Availability and pricing can vary by extension, so check the options when you register.
05. Connect your site and email
Connect your domain to your Wix site and set up a matching business email from one dashboard. If you registered both versions, point the second domain to your main site.
Beyond registration, Wix includes built-in tools for DNS management and domain security, along with a free SSL certificate to help protect your site and visitors.
.io vs .com FAQ:
Is .io better than .com?
Neither is better across the board. .com is the more familiar choice for most audiences and isn't tied to the status of any territory. .io can be a strong choice for tech startups and developer tools, especially when the .com you want isn't available.
Does a .io domain hurt SEO?
No. Google treats .io as a generic top-level domain, so it doesn't inherently target one country and isn't penalized for its extension. Your content, site quality and other search signals have a much bigger effect on visibility than the letters after the dot.
Why is a .io domain more expensive than a .com?
A .io is generally more expensive to register and renew than a standard .com. The exact gap depends on the registrar, any promotions, the registration term and the renewal rate, so compare the full renewal price before you buy.
What about .com vs .net vs .io?
The .net extension was originally meant for network and internet infrastructure companies, but anyone can register one today. It's widely recognized, though usually less familiar than .com, which makes it a common fallback when the .com you want is taken. Like .io and .com, it gets no automatic SEO advantage, so choose it for availability and fit rather than rankings.
Is .io good for a non-tech business?
It can work, but it's rarely the most natural fit. Many everyday customers may not recognize .io and could type .com by mistake. If you run a shop, restaurant or local service, a .com or an extension that matches your industry usually serves you better.
Can I switch from .io to .com later?
Yes. Many companies start on .io and move to .com once the name becomes available or their audience grows. Plan the move with 301 redirects from every old URL, updated email addresses and a heads-up to customers so you protect your traffic and search visibility.
Is the .io domain going away?
Not right now. .io remains an active country code domain. The UK and Mauritius signed a sovereignty treaty for the Chagos Archipelago in 2025, but its implementation remains unresolved, and a change in sovereignty wouldn't automatically retire the extension. If retirement were ever triggered, IANA's standard policy allows a five-year transition that can be extended by up to five more years.
