I need to find some useful marketing ways to promote software. Anyone can help?

any means, if effective.

1. Setup your own website. It's important that you have your own website to sell software. Somehow, this gives your potential clients an assurance that you are not a fraud. Make your website informative and make it look professional so your visitors will not think twice about doing business with you. Make it search engine-friendly and easy to navigate.

2. Submit your software to major download sites. Therefore your software will be known to hundreds of thousands of customers that searching for certain kind of software on software download sites. The all-inclusive and convenient nature of download sites will attract the potential customers of your software, and bring much larger traffic to your sites, which in return will help you reach more potential customers that do not search for software on download sites. But if you submit your software to these sites all by hand, that will cost you lots of efforts and time. So using an auto submitter would be a better choice.

Judging from my own experience, PAD Submit Work is the best one I have used. You can download it at www.submitworker.com/.

3. Article marketing. Personally, I highly recommend article marketing as it is not only cost-effective; it also delivers great results as long as you do the entire process right. Just write and submit highly informative articles online and you'll surely be able to get the kind of exposure that you need. For best results, write topics that are closely relevant to your software, to the problems being faced by your prospects, and issues that affect your chosen niche to attract high quality traffic.

4. Blog-posting and Forum-posing. Feature your software on blog and forum can help you dramatically boost your sales. Though it is very time-consuming, the result will be beyond your imagination. You will help your potential customers know more about the features, selling points, and benefits of your software—like a complete report of the software. And eventually you can gain their trust and convince them to buy your product.
