Yes, initial marketing would normally look for a target audience (Not just on the internet - get on the phone too). Spend some time on forums, blogs, etc.

Find websites that allow you to write about your product(s) (What it is, why people should use it, etc).

Maybe even getting in contact with tech-based magazines. Ask if they can do a review of your products (Or hell, even feature the product/link to the product on a cover CD if they have one).
