You can also do it by hand. Or, I have used ineedhits.com for years to start getting sites listed – it is very inexpensive and effective. Just use the premium submit service. Costs you $20 and they submit by hand.
But it is also worth your time to spend some time surfing and submitting wherever you find people allowing you to add to directories. There are a lot of small sites that offer listings for free. Don’t ask me where they are though – I have no idea. You just need to surf your subject matter and find what’s out there today. I haven’t done it in ages, but it helped get me off the ground.
