Making the Decision

Choose .com When:

• Need maximum trust
• Planning global expansion
• Budget allows premium purchase

Choose .ai When:

• Building AI/ML products
• Targeting tech-savvy users
• .com unavailable/unaffordable
• Want to signal innovation
• Industry alignment matters

Choose .io When:

• Building developer tools
• Targeting programmers
• Creating tech infrastructure
• .com too expensive
• Community over consumers

The Hybrid Strategy

Many successful companies use multiple:

Primary: example.com
Product: example.ai (for AI features)
Developers: example.io (API/docs)

Examples:

• Notion.so → Notion.com
• Character.ai + Character.com
• Vercel.com + Vercel.app

Future Outlook

Trend Predictions 2025-2030

.com: Remains dominant

• Scarcity drives prices higher
• Trust advantage persists
• Mobile importance grows

.ai: Niche expansion

• AI boom drives adoption
• Prices stabilize
• B2B acceptance grows

.io: Developer standard

• Technical tools default
• Consumer confusion remains
• Price stability

The Bottom Line

Data shows .com still delivers the best ROI for most businesses. The trust, conversion, and recognition advantages outweigh the higher costs.

But context matters. An AI startup genuinely benefits from .ai. A developer tool fits naturally on .io. The key is matching your domain to your audience's expectations.

Don't let perfect be the enemy of good. A great .ai or .io domain beats a terrible .com. But when you have the choice, the data is clear: .com still rules.
