Once upon a time I used to advise other writers that if the .com name they wanted wasn’t available to get the .net extension instead. Dot net websites were fairly common at the time. And whenever I registered a new domain, I would get both .com and .net. This was to prevent someone else with the same, or similar, name as mine from getting the .net and creating confusion.
The Internet, however, is an ever changing landscape. What may have worked five years ago, or even last year, may not apply today, Such is the case with the .net extension. Over time we’ve learned that people will automatically go to .com out of habit, even when .net was clearly posted. It’s sort of like my name, Gayle. Not a bad name, I suppose, but it has the less common spelling. And no matter how many times I spelled it out for people, they still give me the more common, Gail.
So please disregard my earlier advice. From what I’m seeing now, the .net extension is becoming extinct. And you certainly don’t make yourself look dated. If the .com isn’t available, you’ll have to come up with other variations. If you’re an author, try adding, author, writer, or books to your name. And even if the .com version of your name is available, I still recommend getting authoryourname.com or yournamebooks.com with it. Domain names usually aren’t that expensive. However, they’re crucial for building your brand and promoting your book. Therefore, it doesn’t hurt to grab as much Internet real estate as you possibly can.
