I have created my own internet marketing software. Anyone can suggest ways to promote it? I prefer free advertising for now.
You can also utilize article marketing to help bring targeted traffic for the software. You say you're interested in free advertising, so let's just hope that you're a bit skilled at writing. Otherwise, you'll need to outsource. You could also do some blogging, on your own or as a guest. Social bookmarking works to spread the word, too.
Software directories and forums are great way to promote. You can download an automatic submitter to submit to siftware directories.
Of course it's a good idea.Try to find directories as many as possible.Also free version for using is very important. Try to find more places to promote your softwares.Ways such as forum sigature or article submitting are all good .You can have a try.Good luck.
