9 Tips for choosing a domain name

Have you read how to buy a domain name, it’s easy, right? But how to choose the right domain name? The domain name of your website is your important asset, visitors will use this name first before even knowing what your website is. Here are some tips that you should apply to choose your domain name:

  1. Do your research first. You need to know what your customers want. Pay attention to popular keywords and what customers search for. It will help you determine which name is worth representing your big project.
  2. Memorability and readability are paramount. Don’t choose names that are too long and difficult to read. An easy-to-read, easy-to-remember domain name will likely increase traffic to your website because visitors always remember your domain name when they want to find something related.
  3. Choose .com if possible. As always, the .com domain name is the top choice of any project. And with .com, users don’t have to remember this extension because it’s already too familiar, they just need to remember your project name. And that’s the first step to success! Choose a .com domain name if possible.
  4. Check for copyright infringement. To avoid legal problems, do not register domain names that contain too common names, associated with big brands. You can use Copyright Checker to avoid trouble for this reason.
  5. Do not use numbers and dashes. While numbers and dashes can make display domains easier to read, they do more harm than good. For example, a lot of people confuse the number 0 and the letter o, or the number 2 and the word two. So don’t use numbers and dashes are best.
  6. Buy more similar domains. If you’ve found a domain name that you like, but keep buying more domains that have the potential to cause typos, to ensure all traffic from the net is directed to your domain name. It’s like Amazon bought the domain name to point to the website’s home page, or will go to Facebook.
  7. Check names on social networks. Once you’ve chosen a domain name, purposefully place it on social media sites like Twitter, YouTube, Instagram, and Facebook. Even if you don’t plan on getting involved in social media promotion, give it the exact same name to make sure no one else will take it and confuse your project.
  8. Think about the future. Websites and domains are long-term investments. Therefore, choosing a domain name that is only “hot” in a certain time or in social networking trends will not be suitable for a long-term project. Think beyond that and find a more sustainable domain name instead.
  9. Discuss your general idea. If choosing a domain name based on user intent is too difficult, you can ask friends, relatives, and colleagues to discuss. Who knows, maybe they’ll give you an idea, what’s most appropriate.
