You have a message to deliver to your tribe, and it is important. Facebook is how you communicate this message. But its time to change source of your message. Communicating purely through Facebook puts you at the mercy of Facebook and their ever-changing terms of service. Mark Zuckerburg writes all the laws for how you communicate your message.
What this means for you is that for somebody to see your message they have to like your page, but even still they might miss your message in the flood of everything else in their newsfeed. Its also critical that people rate your page with stars – for you to appear at the top of user’s news feeds. Still sometimes Facebook doesn’t deliver your message to all your fans – http://john.do/goodbye-facebook-page/
You need to be able to deliver your message to people regardless of if they have Facebook or not. When the laws of “Facebook land” change (or if they ever force business’s to pay for people to see and of their posts at all), you still want to be able to communicate.
This is why you need a website. You decide when where and how to communicate. You can tie in with Facebook and Twitter but your brand won’t live or die based on the decisions they make. This enables you to take advantage of all the good of Facebook but when it comes down to it, you are in charge of your content. When another social media platform emerges on top, you won’t have to build from the ground up again. Do yourself a favor and future-proof your brand’s communications. Facebook alone won’t cut it anymore. You need a website.
