You can use a word or phrase as a domain name. If the domain is for a company, you might want to put your company name in the domain, this makes it easier for your customers to find you on the Internet.
Although a longer domain is harder to remember, it can contain more keywords, which is important as some of the search engines use keywords in a domain name as part of the search algorithm. But be careful of domain names that are too long, it makes it difficult to remember and prone to user input mistakes.
If your preferred domain name is not available, try adding a prefix, such as “my” or “the”.
And finally, make sure your domain name can be verbally communicated. You do not want to constantly repeat or spell it out.
