Here's my experience from releasing a number of products, including Banshee Screamer Alarm, and PhotoWipe. Whenever you install my software, it opens a "thank-you" page, so I can track downloads vs. installs, which is important for your analytics.
- First of all, did you get your friends and family to try to use your software? It's not ready until somebody can use it without you standing there helping them!
- Although my software was listed on hundreds of sites, including cnet downloads, freedownloadscenter.com consistently ended up giving the majority of the downloads, followed by softpedia. Note that the download counts on both CNET and freedownloadscenter are either broken or have no basis in reality.
- The editor at freedownloadscenter sometimes picks things to review. Maybe you can email them. Being on the front page for a few days nearly melted by server.
- To cover everybody else, fill out a PAD file and list it in the ASP directory. All the other download sites on the planet will pick it up from there. Ignore all the emails from spammy download sites and their annoying awards.
- Then, get emailing bloggers. That will be the majority of your promotional work.
You are missing an installer, and seem to be proud of it. Is your product for only software developers? "After I restart my computer it disappears," will be your first complaint.
Edit: I have a general feeling that windows users are less likely to buy software than mac users, but I don't have any proof.
