A key part of Wells Fargo's business strategy is cross-selling, the practice of encouraging existing customers to buy additional banking products.[18] Customers inquiring about their checking account balance may be pitched mortgage deals and mortgage holders may be pitched credit card offers in an attempt to increase the customer's profitability to the bank, and to make it more difficult for the customer to switch to a different bank.[19][20] Other banks have attempted to emulate Wells Fargo's cross-selling practices (described by The Wall Street Journal as a hard sell technique);[19] Forbes magazine describes Wells Fargo as "better than anyone" at the practice.
