Your URL or domain name is one of the first things that both search engines and visitors see on your website. Ideally, you want to choose a URL that includes your business name.
Ideally, your domain name should be your business name. Try to avoid kitschy spellings, adding extra vowels or difficult pronunciations. Something like, "nameeeme.com" will be really hard for your customers to remember. Ever see the movie, "That Thing You Do!" based on the musical group, the Wonders? Originally, their name was the One-ders. They thought it was cute but people kept pronouncing it, "OH-NEE-DERS." Not as cute, right?
So really put a lot of time and thought into your business name, consider rebranding if the name isn't working out. Ask for truthful opinions from people you know won't try to spare your feelings. Business is not a cuddly blanket of compliments.
