DMOZ doesn’t find you (search engines will eventually index you whether you submit to them or not). You have to submit to it, and you typically wait months (or even years) before they even take a look at your submission and see if it’s worthy. I’m still waiting to hear back on the how-to-make-jewelry.com site from 2 years ago. By all means submit your site to it, but don’t hold your breath about getting listed.

The search engines do give it weight though in terms of ranking so if you can get on it, that’s awesome!

And watch the SEO for Firefox video (the 2nd one) again – I’m sure I say stay away if your keywords bring up Google results with DMOZ listings and Yahoo directory listings.

(The rumor is that the DMOZ volunteers are mainly affiliate marketers so if you have any affiliate links they’ll bypass you so you don’t compete with them. Another rumor is that many will sell their children for 12 extra website visitors a day. That one makes me laugh).

Regarding a license, that depends on where you are and what you want to do exactly. Selling online, you don’t need a “license” but you should register your business and here in Ontario Canada I need to register as a vendor to get wholesale pricing and not pay provincial sales tax on supplies. The rules will be different depending on where you live, so you should contact your local government office that handles small business registration and information.

If you do shows and booth vending, you should also get insurance coverage for sure. If you sell only online, your house insurance may cover you in case of theft from your home or fire, etc.
