If a domain is not available, it means that it has already been registered by someone else. In that case, you'll need to choose another domain name. Here are a few options:

1. Try a different TLD: If the .com version of the domain name you want is not available, consider using a different TLD such as .net, .org, or a country-specific TLD.

2. Add a word: Add a word to the domain name to create a new domain name. It could be an adjective that describes the name or a word that indicates the niche of your website.

3. Change the spelling: You may consider changing the spelling of the domain name. For example, by adding or removing letters or by adjusting the spelling of a word.

4. Purchase the domain: If the domain name you want is already owned by someone else, you could consider reaching out to the owner to see if they are willing to sell the domain name. Keep in mind that this option is often expensive.

Remember that it's important to choose a domain name that fits your website and target audience. A good domain name can help make your website easier to find and remember, while a bad domain name can lead to confusion and less traffic to your website.
