When was the last time you went on Twitter/FaceBook (FB) for your daily round of knowledge (articles)?
It's where everyone goes for gossip and to find out what's currently new. People don't visit these sites to learn about their favorite subjects.
If your site is suffering from Twitter/FB it's because you don't offer fresh content - such as having great discussions, How-To tutorials, downloads, articles, etc.
Compounding this is the lack of usability on most sites - Twitter/FB is 10x more user-friendly than most sites.
How easy is it to find fresh content on your site? Do you provide your readers a list of new titles or do you expect the reader to do all of the work?
Do you know your registration conversion rate? I bet it's low.
How do you expect to succeed when conversion rate is so low?
If you REALLY want to succeed you need to start focusing on content and usability.
- Fresh content helps drive traffic to your site.
- A user-friendly site makes it easier for your visitors to find what they want; register, and participate.
