The folks at Tims garden Centre in Campbelltown use social media well to connect with the local area and to compete with big retailers. This post from them showing off the performance of their potting mix compared to that from a big retailer is a perfect use of social media. They market by showing. The evidence speaks for itself in terms of the superior products they sell and in terms of people who engage with their Facebook page.
Social media posts need to entertain, inspire and / or help people feel good. What they do at Tim’s Garden Centre is ideal.
