Please take "Niche" keywords to represent the site. Keywords will lead to the enhancements of your SEO.
Choose a domain that resonates with your niche like if you offer dog food then try to pick a domain that has either "Dog" or "food" or something that matches your business. Select a name that is short, attractive, and easy to remember. You can also go for premium domains as they are unique.
