Why Industry Context Changes Everything
A .io domain signals credibility in a developer tool audience. That same extension raises eyebrows for a family law practice. Domain name conventions are cultural β they vary by industry, audience, and geography. Getting it right means understanding what your specific audience expects.
Technology and SaaS
Recommended extensions: .com, .io, .ai, .app, .dev
The tech industry has the most flexibility. .com remains the gold standard for credibility, but .io and .ai have genuine traction with technical buyers and investors. For developer tools specifically, .app and .dev are well-recognized.
Naming patterns that work: Short, coined names (Stripe, Linear, Vercel) or descriptive compound names (GitHub, Cloudflare). Avoid generic descriptive names β they're taken and unmemorable.
E-Commerce and Retail
Recommended extensions: .com, .store, .shop
Consumer-facing retail audiences have the strongest .com expectations. A non-.com extension for a general e-commerce store requires more marketing effort to establish trust. For niche stores where the extension is descriptive (e.g., bloom.store), it can work well.
Naming patterns that work: Short, memorable brand names. Avoid hyphenated names or names that are hard to type β mobile shoppers need to get to you quickly.
Healthcare and Wellness
Recommended extensions: .com, .health, .care
Healthcare audiences trust .com most. Newer extensions like .health add descriptive clarity but are not yet universally recognized. For practices that serve a specific geography, a country-code TLD (.co.uk, .ca) can signal local relevance effectively.
Naming patterns that work: Professional, clean names. Avoid overly clever or informal names β your audience expects a degree of formality. Names that include the clinic's location or specialty work well for local SEO.
Legal and Financial Services
Recommended extensions: .com, country-code TLDs
Law firms and financial advisors face the most conservative audience expectations. .com is the clear choice. Country-code TLDs are appropriate for regionally focused practices. Newer or experimental extensions are likely to hurt credibility with clients.
Naming patterns that work: Firm name plus practice area (e.g., smithandpartnerslaw.com) or surname combinations. Geographic naming works well for local practices.
Education and Online Courses
Recommended extensions: .com, .academy, .education, .school, .courses
Educational platforms have more flexibility than traditional institutions. Course marketplaces and edtech startups can credibly use .academy or similar extensions β they're descriptive and memorable. Traditional schools and universities are expected to use .edu (restricted to accredited US institutions) or country-specific education TLDs.
Naming patterns that work: Descriptive names that include what is being taught, or aspirational brand names that convey learning and growth.
Creative Services
Recommended extensions: .com, .design, .studio, .art, .photography
Creative audiences are the most accepting of non-.com TLDs. A design agency with a .design domain signals awareness of the industry and attention to brand detail. A photography studio on .photography is immediately clear about what they do.
Naming patterns that work: Short, distinctive names. A creative professional's domain is itself a brand statement β make it count.
Hospitality and Food
Recommended extensions: .com, .restaurant, .bar, .cafe, country codes
Restaurants, hotels, and food businesses primarily serve local or regional audiences. A local .com name is often the best choice. For restaurants specifically, .restaurant and .bar are available and descriptive, though recognition outside the industry is still limited.
The Universal Checklist
Regardless of industry, evaluate any domain name against these criteria:
- Will my specific target audience recognize and trust this extension?
- Does the name work well in the context of email addresses (i.e., [email protected])?
- Is it easy to say aloud without confusion about spelling?
- Does it look professional in a business card or email signature?
- What's the 3-year renewal cost compared to alternatives?
When in doubt, .com wins. When .com isn't available or priced as a premium, choose the extension that your specific industry has already validated.
