.io vs .com: Which Should You Choose?
Price, trust, SEO and resale value — compared honestly, with a decision rule at the end.
Updated June 2026 · Namizy Guides
The comparison that actually matters
Price: .com typically $10-16/year; .io typically $30-60/year. Over a decade that's a few hundred dollars of difference — irrelevant next to the brand decision. Trust: .com is the default in every demographic; .io is equally trusted inside tech and slightly foreign outside it. Availability: this is where .io wins — the namespace is far less saturated, so clean one-word and two-word names are still findable. Resale: .com dominates; treat .io as an operating expense, not an asset.
When .io is the right call
Your users are developers or technical founders; your product is a SaaS, API, devtool or AI/data product; the exact brand word matters more than the extension; and the .com for your name is parked at a five-figure ask. In that scenario .io buys you the brand you want now, at startup prices, with zero credibility loss in your audience.
When you should fight for the .com
Consumer products, anything marketed offline or by voice (podcasts, radio, word of mouth), and businesses where email deliverability and "looking established" matter from day one. If your audience includes non-technical buyers, the .com isn't vanity — it's leak prevention: every mistyped .com visit lands on whoever owns that name.
The decision rule
Check both with the availability checker. If the .com is available, register it — done, no debate, and grab the .io as a defensive redirect if you're in tech. If the .com is taken: developer-facing → launch on .io and budget to acquire the .com after traction; consumer-facing → generate alternative names until you find one whose .com is free. The AI generator is built for exactly that, and the appraisal tool tells you what the taken .com might cost to buy.
Frequently asked questions
Does Google rank .com higher than .io?
No. Both are treated as generic TLDs; rankings come from content, links and user signals. Any SEO difference is indirect — .com gets marginally better click-through from general audiences because it looks more familiar.
If I buy the .io, should I still try to get the .com later?
Yes, and budget for it. The standard playbook is launch on .io, then acquire the .com after traction (Notion, Stripe-adjacent tools, countless SaaS did this). Expect aftermarket .com prices in four to six figures for decent names — the earlier you buy, the cheaper.
How much traffic does a .io lose to the .com?
Estimates vary by audience; for developer products it's small, for consumer products it's real. Direct type-in users defaulting to .com can be several percent of brand traffic — which compounds if the .com hosts a competitor or parking page.
Which is worth more at resale?
.com, by an order of magnitude. Premium .com sales regularly hit five to seven figures; comparable .io names typically sell for a fraction. If domain-as-asset matters to you, .com is the only serious store of value.
