Radio test : Your domain name should not contain ANY underscores

Domains are only valuable if they meet certain criteria, and AuthorMedia has put together a nifty guide about it all.

According to Thomas Umstattd, if you want to secure the perfect domain, it’d better fully pass the radio test:

  1. Numbers are out, they can be spelled as digits or letters.
  2. Similar sounding words, like “see” and “sea” are also out.
  3. Acronyms like YMCA or IBM are out. Or maybe not, just these two are ok, the rest aren’t.
  4. Underscores are also out.

Wait, what?


We don’t use any stinking underscores in domain names!

I don’t know about you but I only use underscores for my kick-ass handle on Counter-Strike. But definitely not in domains.

With domain names, you can only use letters, numbers and the humble dash “-” but domains can’t begin or end with a dash.

Simple enough? Here’s a guide.

Perhaps someone distracted Thomas, author of this guide, and added an extra bullet point for a total of seven.

    Actually, some of us get to use underscores. It’s an obscure RFC for we elites. Don’t question it.

  2. I miss playing counter-strike.

    In 2008 I got a really nice name from the drop and built a nice gaming community on it and ran it for 2 years until I sold it in 2010.

    What timing of this blog post because I am learning about brandable domain names. There’s one that I have been thinking about but I now see that it wouldn’t pass the radio test because of the letters “o” and “u”.

    Thank you.

    We are in the age of voice search technology, The Internet of Things (IOT) and 5G speeds; these technologies are fast making the radio test obsolete as when someone says C; Sea; or see when searching the internet, it all depends upon the words said before, or after C, Sea, or See which will determine the results one gets e.g. “C is a letter of the.” or “a boat on the Sea.” voice search is making the type-in obsolete as well. I urge you to try the voice search test using numbers as well, for instance, if I say “one bank” voice search will show “1 bank”, but if I say “bank 1”
    it will show as “bank one”, if I say “5G” it will show “5G”, so people don’t need to worry, because 99% of all internet searchs (Domain Names) will be phrases. I guess I’ll “See” what you guys have to say.
