Sam’s Club, Aldi, and USAA earned the top spots in the 2012 Temkin Loyalty Ratings while Citigroup (banking and credit cards) and Charter Communications (TV service and Internet service) each show up twice in the bottom four. We asked 10,000 U.S. consumers to rate their loyalty to companies across three dimensions: likely to recommend, reluctant to switch, and willing to repurchase. Their responses allowed us to rate the loyalty of customers to 206 companies across 18 industries. One-quarter of companies have “strong” or “very strong” ratings while 50% have “weak” or “very weak” ratings. At an industry level, grocery chains and retailers have the most loyal customers while internet service providers and TV service providers have the least loyal customers. USAA has the most loyal customers across three industries, banking, insurance, and credit cards. When comparing the results from the 2011 and 2012 Temkin Loyalty Ratings, we find that PNC and USAA improved the most and Kohl’s and Hyatt declined the most.
