Is .ai or .com better for a domain?

For most businesses, .com is still better — it has the highest consumer trust, is the most remembered, and is what people type by default. However, .ai is the right choice if you're building an AI product or tool and .com is unavailable or unaffordable. The .ai extension signals 'AI company' immediately to your target audience (developers, tech-savvy founders, investors), which can be an advantage in that specific market. If you're building anything outside the AI space, stick with .com.

Is .io good for a startup?

.io became popular for tech startups in the 2010s and is still widely recognized in developer and SaaS circles. It's a solid choice if .com is unavailable and your audience is technical. However, .io is the country code TLD for the British Indian Ocean Territory — it has no formal regulatory status as a 'tech domain' and there have been concerns about its long-term stability. If you're choosing between .io and .ai for a tech startup, .ai now carries more brand signal in the AI era. For non-technical businesses, avoid .io.

Does your domain extension affect SEO?

The domain extension itself does not directly impact Google rankings — Google has confirmed that all TLDs are treated equally in search. What does affect SEO is user trust (which affects click-through rates) and domain authority (which is built over time regardless of extension). A .com domain tends to get more clicks in SERPs because users trust it more, which indirectly improves rankings over time. Country-code TLDs (.ai, .io, .co) may also be interpreted by Google as geographically relevant to their country of origin, though Google now treats most of these as generic.

What is the .ai domain used for?

The .ai domain extension is the country code TLD for Anguilla (a Caribbean island territory), but it has been widely adopted as the de facto domain for artificial intelligence companies, tools, and startups. Companies like Runway.ai, Character.ai, Perplexity.ai, and thousands of AI tools use .ai domains specifically to signal their AI focus. If you're building an AI product, .ai is now an industry-standard choice alongside or instead of .com.

Which domain extension is best for ecommerce?

.com is by far the best domain extension for ecommerce. Shoppers are most familiar with .com, it's associated with commercial legitimacy, and it's what customers type from memory when searching for a store by name. For Shopify stores and ecommerce businesses, .com is the clear choice. If .com is unavailable, .shop and .store are purpose-built ecommerce alternatives with growing recognition.
