Key takeaways:

  • .com is by far the most trusted extension, with two-thirds of consumers describing it as “extremely” or “very” trustworthy
  • No surveyed consumers considered .com or .org untrustworthy
  • A quarter of consumers don’t place implicit trust in .ai or .io domains: brands using these extensions need to work harder to build trust.

Objective: The scarcity of clean .com domain names means many brands are turning to alternatives, from .co for diverse industries to .ai and .io for tech-based brands. Domain name can play a key role in first impressions of trust online, so we sought to discover when, and to what extent, consumers place implicit trust in a domain name. Beyond top-tier, trusted extensions brands may need to work harder to build trust by matching these TLDs with one-word names and clean, clear brand identities.

Surveyed extensions:

Conclusion

Despite the growing usage of alternative extensions, consumers still consider .com to be the gold standard for trust, with .org coming in at a close second. Meanwhile, popular tech extensions, including .ai and .io don’t bring implicit trust among consumers. That doesn’t mean they can’t be a strong foundation for brands in relevant industries: but any founder considering an alternative extension must choose an extension that their audience knows and understands, and such an extension may mean working harder to prove yourself to your customers.
