Create a Facebook Fanpage
Facebook page is one of the best places to reach your audience, and with it, you don't need to keep bothering your users through email (as users see emails as burdening to-do items). It's a much better way to make frequent conversation with your users.
The Trick Here this: very few people know about creating good Facebook Fanpages is that you should not create a page that promotes your own product. In fact, it's never good to create content that just promotes your products. The only thing you can do is to provide content that you think your ideal customers would like to read about. However, you could mention about your solution if it is relevant to the topic at hand.
With Facebook pages, the point is that you can should create a page for a topic that you think could attract your ideal customers.
For example, if you are operating a fantasy basketball website, you can consider creating a page on "I love NBA". If you are operating a dating website for New York, then you can consider creating a topic called "Best New York Hangout Spots". You can then also drive them to your company's fanpage (separate fanpage) or to your website directly.
So, the trick to creating a great fanpage is like creating a great blog. The titles and content should address your customers' pain points, and not to promote your company's products. Of course like the Cisco example, when applicable, you should find every chance to promote your solution.
Like building influence on Twitter. These pages take time to build up. So you must start to build it up as soon as possible.
Post your demo page on your Facebook fanpage.
Ask your friends to help promote it and pass it to their friends. You have to ask to get people to actually spread the word.
