Marketing is not about telling "the truth"; marketing is about telling the story of your brand to those predisposed to believe it.
STOP talking about yourself. Don't post a fact sheet of components and capabilities - tell a story of benefits and advantages.
It's not what your product does (features and functions): it's what it does FOR THE BUYER (values and desires).
Promotion is to remind existing customers of the emotional connection made by Marketing and the benefits established in your Advertising Campaign.
To move them from Brand Awareness to Brand Preference.
Your Brand Here...
It's not about what your product does - it's about who your product does it for.
Speak to them - not at them. Find out what they want, directly from them, when possible.
