# What is your "primary" domain?

Articles on: [Domains](/en/category/domains-1kruoyz/)

  
  
Your primary domain is the main URL that will show in the address bar when someone visits your online store. A Launch Cart store can only have one primary domain, all other domains will become redirects to the primary domain.

Login to your Launch Cart store admin, go to >Settings>Custom Domain and press the "Make Primary" text link next to the specific domain you want to become your primary domain.  
  
If you have both a root level domain, and a WWW subdomain available, we recommend that you make the root level domain your "primary" domain url.  
  
If you're having trouble with a domain not verifiying or showing errors, please ensure your DNS doesn't include any...  
*   Duplicate entries relating to your Launch Cart DNS changes.
  
*   If you're using CloudFlare, disable the orange proxy symbol for Launch Cart related DNS entries.
  
*   If your Domain or DNS has DNSSEC enabled, please disable this. (You might need to look at the registrar level for this setting sometimes)
