While very creative domain extensions are popping up these days (such as .pizza, .photography, or even .ai), I have found that .com is still the king. First, it's intuitive: Most users instinctively type “.com” at the end of every domain, and even autocorrect is more likely to add that. Second, it helps prevent unwanted user experiences. If you choose another extension and the user wrongly types in .com, you risk leading the user to an error page. Worse, if it is owned by another company, you may lead them to the wrong website and lose a prospective customer!..
