As of July 2024, there are over 1.5 million registered .io domain. And currently, the .io domain ranks 49th among top-level domains, with 221,191 active websites.

But what does .io mean, and why has it become so popular?

This article will delve into the origins and meaning of the .io TLD, highlight its unique advantages, and explore the scenarios where it might be the perfect choice—or not. Ultimately, let’s determine when it is the right fit for your website needs.

What are TLDs (Top-Level Domains)?

A top-level domain (TLD) is the part of a web address that comes after the final dot. For example, in ‘google.com’, the .com is the TLD. TLDs are important for finding and organizing websites on the internet.

There are different types of TLDs. Generic TLDs like .com, .org, and .net can be used by anyone. Country-code TLDs like .uk for the United Kingdom and .de for Germany are only for specific countries. Each type serves a unique purpose.

As of 2021, there are more than 1,500 TLDs in the Internet Assigned Numbers Authority (IANA) root database, showing the wide variety of options available. The .io domain extension, in particular, is becoming popular in the tech industry.

As of March 2023, there were 1,089,147 registered .io domains, with a 32% year-over-year growth. In fact, the .io domain has become increasingly popular, particularly among tech startups, developers, and gaming companies.

TLDs help organize the internet and show the purpose or location of a website. So, what does .io mean and can you use it for your website?

Overview of .io

The .io domain extension is a unique top-level domain initially assigned to the British Indian Ocean Territory (BIOT). However, because the region has no significant population and permanent residents, its use quickly expanded beyond its original purpose.

This TLD  is now adopted by a broader audience, specifically in the tech industry. Over time, it became more than just a regional domain, evolving into a global brand symbol.

It’s now widely used by tech startups and innovative companies. One reason for this is its association with “input/output” (I/O) in computer science. Its technical connotation aligns well with the goals of many modern tech companies.

Despite its association with the British Indian Ocean Territory (BIOT), it is widely used for its tech-savvy appeal, representing input/output in computing.

Benefits of Using .io Domain Extension

Availability

One of the main advantages of using a .io domain is its higher availability compared to traditional domains like .com. You’re more likely to find a desirable and memorable name that suits your brand without needing awkward modifications or hyphens. Many .io domains are still open for registration.

The .io domain is used by only 0.4% of all websites. This lower usage means there’s less competition for names, making it easier to secure a unique and relevant domain for your site.

SEO Considerations

Google treats .io domains as generic top-level domains (gTLDs), meaning they aren’t tied to any specific country. This is good for SEO because it allows .io websites to show up in search results worldwide.

Using a .io domain can help your site reach a global audience and boost your SEO efforts. It’s a viable option for businesses looking to optimize their presence on search engines.

Global Appeal

The .io domain enjoys universal recognition beyond the British Indian Ocean Territory. It is used by tech companies and startups worldwide, which contributes to its broad appeal. 

This makes .io suitable for businesses targeting a global audience, as it is not tied to a specific country and is perceived as a modern and innovative choice​​.

Short and Easy to Remember

The .io domain is appealing because it is short and simple. Its brevity makes it easy to remember and allows for creative and catchy domain names. This can significantly help with branding for a business or project.

In today’s fast-paced world, having a concise and easily recognizable domain name is important. It helps establish an online presence quickly and effectively.

Additionally, a short and memorable domain name can make your brand stand out. It ensures that visitors remember your site and find it easily, which is crucial for maintaining a strong online identity.

When to Use a .io Domain

If you’re in the Tech Industry

Using a .io domain is very popular among tech startups and companies because it fits with industry norms and trends. The term IO itself stands for “Input/Output,” which immediately signals that you are part of the tech world. This makes it a great branding choice that is cost-effective but highly impactful.

Having a .io domain also helps connect a startup with a community of other tech founders. It shows pride in being part of the tech startup scene. Many founders choose .io for this reason, especially when their preferred .com domain is not available.

Use Cases in Various Sectors

SaaS (Software as a Service)

Many SaaS companies use .io to emphasize their tech-oriented solutions and innovative approach. Here are examples of SaaS websites that use the .io domain:

• Tyk (tyk.io) – Tyk is an open-source API gateway and management platform that offers tools for managing, monitoring, and securing APIs.
• Memberstack (memberstack.io) – A tool for adding user accounts and payments to Webflow sites without code.

AI (Artificial Intelligence)

AI startups use .io to highlight their focus on advanced technology and artificial intelligence developments. Below are some AI websites that use the io domain.

• TeleportHQ (teleporthq.io) – An AI-driven platform for building websites with visual editing.
• Seldon (seldon.io) – Delivers machine learning deployment solutions.
• Aira (aira.io) – An app that links individuals who are blind or have low vision to professional visual interpreters

Blockchain

Blockchain companies use .io to underscore their involvement in pioneering and disruptive technologies​.

• OpenSea.io: A large web3 marketplace for crypto collectibles and NFTs.

When Not to Use a .io Domain

Non-Tech Industries

For businesses outside the tech industry, using a .io domain can create confusion or misalign with the brand’s identity.

For example, a bakery or a law firm using a .io domain might not connect well with their audience since the .io extension is closely associated with technology and innovation. This can lead to a mismatch between the domain name and the industry norms and expectations of these businesses.

Additionally, customers might find it strange or misleading if a non-tech company uses a .io domain. This could affect the credibility and trustworthiness of the business in the eyes of potential clients who expect domain names to reflect the nature of the business.

Another important aspect to consider is that .io domains tend to be more expensive and less recognized than traditional domains like .com or .net. This might not be a worthwhile investment for non-tech businesses that do not benefit from the tech-savvy perception that .io domains offer. 

Local or Regional Businesses

For businesses targeting local or regional markets, using country-specific TLDs like .us, .uk, or .de is often more effective. These TLDs help build trust and relevance with local customers.

A domain that signifies a specific country can make customers feel more connected to the business. This is something a .io domain might not achieve as effectively.

Moreover, using a ccTLD can help businesses tailor their marketing efforts to the local audience. It allows for more precise targeting in advertising and search engine optimization.

This localized approach can drive more traffic and conversions from the target region, making the business more competitive in its local market.

Cost to Register a .io Domain

The popularity of .io domains among tech startups and companies has driven up their prices, with the registration cost varying depending on the registrar and specific offerings. 

For example, GreenGeeks offers .io domains for $49.95/year, with a renewal price of $49.95/year.

Registering Your Domain Name in GreenGeeks

Registering your .io domain with GreenGeeks is simple. First, if you are setting up a hosting account, you get one free domain name. Just click on any “Get Started” green button on the plan you want. You will then be guided through the hosting and domain registration process.

If you’re trying to register another domain, follow the steps below:

• Log in to your GreenGeeks account.
• Click on “Domains” in the left menu, then select “Register a Domain.”
• Enter the domain name you want and click “Domain Lookup” to check if it’s available.
• If the domain is available, you’ll see a confirmation message. Click “Go To Next Step.”
• If the domain isn’t available, try different variations or extensions like .net or .biz.

• Your domain is now registered!

How to Transfer .io Domain to GreenGeeks

Transferring your .io domain to a new registrar like GreenGeeks can streamline your website management and billing by consolidating them into a single account.

The entire process of transferring is straightforward, but there are a few prerequisites:

• The domain must have been registered for at least 60 days, as domains are ineligible for transfer before this period.
• Avoid transferring a domain for 45 days after renewal due to an ICANN rule; doing so could void your renewal credit, requiring you to seek a refund from your previous registrar.
• If your domain is expiring within two weeks, renew it with your current registrar before initiating a transfer to avoid complications.

Starting a transfer before the domain expires is possible, but the domain will enter a pending transfer state and become unavailable until the transfer is complete and the new registrar renews it. If the transfer fails, especially after expiration, you may face additional fees or be unable to restart the transfer process.

Here are the steps you can take if you want to transfer your .io domain name to GreenGeeks.

Step 1: Verify Your Contact Information

Make sure you are listed as the “Admin Email” in the whois record for your domain, as you’ll need to authorize the transfer once initiated.

Step 2: Disable WHOIS Privacy Protection

For the duration of the transfer, you may need to disable WHOIS Privacy Protection. This ensures you can receive and respond to transfer confirmation emails.

Step 3: Disable DNSSEC

If your domain has Domain Name System Security Extensions (DNSSEC) active, you’ll need to disable these settings to prevent DNS resolution issues. Once the transfer is complete, GreenGeeks can re-enable DNSSEC for you.

If you need to keep your DNSSEC records, provide GreenGeeks with the DNSSEC keys before changing the nameservers to avoid resolution failures.

Step 4: Update Nameservers

Change your domain’s nameservers to those provided by GreenGeeks:

ns1.greengeeks.net

ns2.greengeeks.net

Contact your current registrar for instructions on how to update nameservers. Remember, you cannot change nameservers while the domain name transfer is ongoing.

Step 5: Unlock Your Domain

Contact your current registrar to unlock your domain, which is necessary for the transfer.

Step 6: Obtain the Authorization Code

Ask your current registrar for the domain authorization code, sometimes referred to as an “Auth Code” or an “EPP Code.”

Step 7: Submit the Domain Transfer Form

Complete and submit the Domain Transfer Form provided by GreenGeeks to initiate the transfer process.

Domain transfers typically take up to seven days but responding promptly to any authorization emails can expedite this process. Not all registrars can speed up transfers, but quick responses can help shorten the waiting period.

Do’s and Don’ts When Naming Your .io Domain

1. Do Consider Registering Variations of Your Domain Name

Even if you’ve decided on a .io domain, it’s a good idea to register other variations of your domain name. This helps protect your brand and ensures that others don’t take your domain name or hold it for “ransom”.

Securing variant domains can also be useful for email marketing. It allows you to conduct outreach without risking spam penalties to your main domain.

2. Don’t Choose Gimmicky Names for Your .io Domain

Names ending in .io can seem fun and creative, like Mauric.io or Mustach.io, but they can hurt your site’s credibility in the long run.

Although these names might look clever at first, they may not be taken seriously as your site grows in popularity. It’s best to choose a straightforward and professional name to maintain trust and respect from your audience.

3. Do Keep It Short and Sweet

Choose a name for your .io domain that broadly represents your website’s niche. A unique, branded domain name can effectively convey what your business is about. Keep it under two words to make it memorable, as longer names are harder to remember.

4. Don’t Use Hyphens

Using hyphens on your domain name is an outdated practice and can be a red flag for experienced internet users. Keeping your domain simple and clear without hyphens helps maintain a professional image.

5. Do Check if It’s an Expired Domain

While the .io domain doesn’t have heavy competition, it’s still important to check if your chosen name is an expired domain. Use websites like who.is to investigate your potential .io domain.

Look into the domain’s history to ensure it doesn’t carry any penalties or unwanted associations. Also, make sure you aren’t unintentionally infringing on someone’s copyright. This due diligence helps protect your brand and ensures a clean start for your website.

6. Don’t Forget to Check Your Competitors

Before registering your .io domain, Google your shortlisted names. This helps avoid confusion with other websites in your industry. Overlooking this step can lead to legal issues over copyright and potentially cost you a lot of money. Always make sure your domain is unique and distinct to protect your brand.

Conclusion

Choosing the right domain for your website is a strategic decision that reflects your brand’s identity and goals. The .io domain offers a modern, tech-savvy appeal, making it a great fit for startups and innovative companies. However, its suitability depends on your audience’s recognition and understanding of the .io TLD.

Consider what impression you want your domain to create and whether a .io domain conveys the right message. While a .io domain can signal innovation, a .com domain might feel more familiar and trusted to a broader audience.
