In General : your social media networks should always introduce added value to the targeted audience , But How we could do that ?

Its about creating content and your digital content could be :

Moreover, continuous follow-up with your social networks , offering diverted content , & Monitoring your performance  .

Using hashtags, promoting your brand on groups and communities, creating blog around your product, answering all doubts and first of all - thinking like you were your own follower to understand what is needed.

With Tweetup or another social media-induced video tool, take the time to go a little deeper with your strongest markets or partners. That face to face connection can work wonders, and you’ll stand out among the crowd.

“Advertising” on social media can sometimes take the form of extreme discounts and giveaways. In certain instances this can work, such as requiring consumers to buy a cheap product for the chance to win a bigger one. Do your homework, though, and make sure even the worst case scenario will be in your favor financially.

• Stick to the rules of the game (do and dont's of Social Media)
