There is no real rule regarding what should be shared on social media. Most content is good to go provided it follows these three principles:
Adds value for your target audience
Understand your customer pain points and create content that will help solve or at least address those issues.
Touches an emotional chord
Content that provokes an emotional response — whether that’s joy, love, warmth or even fear and jealously — always works better.
Isn’t offensive
While it’s good to be edgy and witty, don’t post content that is offensive or disrespectful. The backlash to your brand is not worth it.
