Hello guys,
take a look at those interesting tips bellow and get ready to take your campaigns to the next level 
1. "Social media is a relaxed medium. The best practitioners often have a sense of humor and a casual style that’s more “backyard barbecue” than “bank manager’s letter.” Social pros should be adept at conveying complex issues in a simple manner that can engage a broad audience, and should be prepared to join in the banter without sounding uninformed or disconnected from the real world."
... and make it sure to have a correct spelling and grammar
2. Promote smartly, whether is starting your content with an attractive info offering an added value to the user, adapting it to the platform (video for YouTube, correct image sizes on Facebook - see my thread where I write about this
or getting creative and offer your traffic for instance an "indoor cricket match between marketing and accounts. Or give them an informal photo tour of your factory. Maybe even share the view of a sunset from the office and challenge your followers to beat it. Find a way to be interesting, entertaining, and relevant. "
3. Point for the engagement. "If you join a group only to push an agenda and spam your special offers, you may find yourself cast into the wilderness very quickly. Instead, spend time joining conversations and building relationships before you start to share your content. "
