It’s easy to get caught up in choosing the “perfect” domain name. So caught up that one can spend huge amounts of time considering and discarding ideas. And sometimes spend huge amounts of money to acquire a domain name that someone else already owns.
I think that effort would be better spent creating content for the website, rather than agonizing over what it is called.
A domain name is important. But it is more important to have a domain name and use it, than to have the perfect domain name.
I recommend choosing a domain name that also has the most common variations available. You want to avoid confusion when somebody doesn’t exactly remember your URL. And if you are a for-profit business, you want to be a dot com, not a dot org or dot net.
If someone else already owns the dot com version of your perfect domain name, you could register the dot net version and start using it. That would immediately drive up the value of the dot com version and make it more expensive to acquire should you choose to do that later. It could also put you at risk of infringing someone’s intellectual property rights. Best to avoid that and focus instead on creating great content.
So choose some other domain name that is available in dot com and dot net versions. Get the dot org version, too, if you can afford it.
You might also consider registering hyphenated versions if your domain name is more than one word. Generally speaking, you want to avoid hyphenated words as your primary domain name. Hyphens do not lend themselves to elegant verbal communications. You want to be able to tell somebody your domain name in an elevator pitch without needing to spell it. But having the hyphenated version in addition to your primary domain gives you some protection against domain squatters.
So scribble down ten or 20 ideas for your new domain name. Check them to see what is available. Then choose one that you can make the most use of right away. Spend your energy building your brand, rather than trying to get the name perfect.
