How to evaluate and buy .io domains: A Domain Investor’s Guide to Smart .IO Acquisitions

Hi, I’m Joe from Domain Academy! If you’ve been following our ongoing domain sales contest on our Season 2 podcast, you’ll know I’m currently in fourth place—so I’m looking for ways to catch up on the leaderboard. Today, I’m sharing my hands-on process showing how to evaluate and buy .io domains using purchasing a premium .io domain: Gilmour.io as an example. I’ll walk you through why I chose this name, the tools I used, and key factors every domain investor should consider—especially when exploring alternative (non .com) TLDs.

How to evaluate and buy .io domains for investment

While I usually recommend sticking to .com for maximum resale potential, strong alternative TLDs like .io can offer unique opportunities—especially in the tech and startup space. However, caution is key: not every alternative TLD will perform well, so thorough research is essential. Let’s look at some key things to consider when figuring out how to evaluate and buy .io domains with principles that can be applied to any other non .com TLD.

Step 1: Using Domain Academy Tools for Research

As a DDC (Discount Domain Club) Pro member at Domain Academy, I have access to 10 proprietary tools designed to simplify domain evaluation. Here’s how I used them for Gilmour.io:

• Research Snapshot: This tool aggregates data from multiple sources, showing me how many TLDs and SLDs (second-level domains) include “Gilmour.” For Gilmour.io, I found 58 TLDs registered and 990 SLDs containing “Gilmour”—a bit lower than my usual threshold, but still promising.
• Search Volume & Advertising: I checked for search volume and active ads, which indicate commercial interest. Gilmour has healthy search volume, and advertisers are bidding on related keywords.
• Radio Test & Brandability: Gilmour.io is a one-word, easily pronounced name, though spelling variations (“Gilmore” vs. “Gilmour”) are worth noting.

Step 2: Analyzing Commercial Use and Upgrade Potential

• Startup & Company Usage: There are 23 startups and over 500 companies using “Gilmour” in their branding—an important indicator of demand.
• Existing Websites: Using our Domain Explorer tool, I saw that most registered Gilmour domains are active—showing real-world usage and strong upgrade potential.
• Upgrade Path: Businesses using longer or less desirable Gilmour-related domains (e.g., GilmourGroup.com) may want to upgrade to Gilmour.io, especially since Gilmour.com is already owned by a major company.

Step 3: Competitive Pricing & Aftermarket Value

• For-Sale Comps: Gilmour.co is listed for $5,000, while I acquired Gilmour.io for just $53.99—a significant bargain.
• Aftermarket Trends: .io domains (especially single-word, personal, or brandable names) consistently appear among the top-selling non-.com TLDs, increasing resale potential.
• Wholesale vs. Retail: Comparable .io domains have sold for $700–$800+ on wholesale marketplaces, confirming my purchase price was well below market value.

Step 4: Evaluating Buyer Pool & Spelling Variations

• Potential Buyers: Startups like Gilmour Space Technologies and individuals with the Gilmour surname represent a robust buyer pool.
• Spelling Analysis: Using our “How Many People” tool, I confirmed that “Gilmore” (ORE) is more common in the US than “Gilmour” (OUR), but both have significant global usage—especially in Australia and the UK.

Key Takeaways for Domain Investors

1. Leverage Research Tools: Use platforms like Domain Academy to analyze TLD usage, active websites, and market comps.
2. Prioritize Brandability: One-word, easily pronounced domains in strong TLDs offer the best resale opportunities.
3. Check Real-World Usage: Existing business use and upgrade demand are crucial indicators of a domain’s value.
4. Buy Below Market Value: Always aim to “make money on the buy”—acquire domains at or below wholesale prices for maximum upside.
5. Consider Spelling and Geo Trends: Analyze name popularity and spelling variants in your target regions.
