I think everyone struggles with this - building something is a lot easier than building something popular. Advertising may be an option. Find relevant communities you can be part of. Write useful, industry-related content and share it with industry-related blogs. Affiliate systems might work. For software/apps/games/etc 3rd party marketplaces, publishers, distributors might help. Persistance is the main factor though. Overnight success is usually backed by hundreds or thousands of overnight experimentation and failure.
