This way, you’ll implement the “wisdom of the crowd” social proof. It’ll influence people’s perception of your company and make a positive first impression. Once consumers see that many people trust and buy from your company, they will think about becoming your customers as well. In addition, you can include the number of countries your company serves and the number of recommendations.
  • Collaborate with industry experts. To drive positive associations among your followers, you need to invite an expert to take over your social media.
