What is a good name for my online store?

[Jake]

You may find a name eluding to what the store sells may help users and search engines know better what they will be getting, this can slightly improve search engine ranking. Fictitious or vanity names may need a bit more Branding promotion in order to catch on. You could resell the business one day, personalized names can complicate this.

There are sites with tools that help you come up with fictitious names, including: wordlab.com, naming.net, wordoid.com, lingzini.com, namestation.com, domainsBot.com some of these tools look up the domain name availability as you go.

If you find an available .com name, there's a high probability that it' not a trademarked name.
