Thirteen banking web sites in Chile were analysed using an adaptation of the Hersey generic web site evaluation model. The model was modified to improve its applicability to the banking sector, and a total of 37 different aspects of Internet based services were analysed. The modified model was applied with uniform weighting for each element. The degree of fulfilment of these aspects ranged from 51% to 86% across the different bank sites. Chilean banking sites perform well in serving their clients, but still many business opportunities are available to them. The modified Hersey model is quite effective in evaluating banking web sites. Web site developers may use these results as a means to improve their sites.
