Twitter is a powerful social media tool and research platform. It can be an advertising and promotional network, but that’s not the best and highest use, unless you are Dell or Best Buy. Even if you are Local Pizza A it is better to include real conversations as part of your tweets. Don’t just blast coupons. Talk about them. Suggest toppings or specials. Sure, coupons are great and coupons can drive business, but give a little bit more and you will get more followers and potentially more happy customers.
