Be yourself.

That’s the advice the best talent coaches give to performers. And one fitness organization advises prospective trainers to “be the big you.”
 
The same logic applies to the “voice” you should adopt when writing social media posts, however brief. Authenticity and transparency are key.    
 
Once you’re up and running, what exactly should you post? An article at http://goo.gl/ghVnt in The Social Media Examiner offers this advice:
 
“Post valuable, useful content that demonstrates your expertise, and encourage your audience to spread your message.
 
Encourage interaction with your market. Instigate conversations. The more participation and involvement you can generate from your audience, the better.
 
Pre-sell. NOT sell. Many business blogs make the mistake of posting exclusively about their sales, promotions and discounts.
 
Exude your brand.
 
Give a taste of what it’s like to work with you: fun, enthusiastic easy, etc…)”
 
After all, the whole idea is to:
 

• Attract traffic
• Convert visitors into leads on autopilot by getting them into your sales funnel
• Establish you as a trustworthy thought leader in your niche
• Convert leads into loyal, raving fans
• Help spread your message and generate buzz by digital  word-of-mouth marketing
