Ready to improve sales through social media? Try implementing "engagement-based loyalty programs." For example, an invite to followers to share a post with 100 friends to get 25 percent off their next purchase can help merchants deepen relationships with current customers and also attract new ones. To enable this, make sure you give your best customers the opportunity to quickly and easily tell their others about your products and services. Have social media links displayed prominently on your website to make it easy for shoppers to tell their friends how great your shop and your products are. Combined with loyalty programs, you can easily encourage your customers to spread the love and then reward them for doing so.
