A method and system for evaluating performance of software applications of different web sites. Steps in a first software application of a first web site are mapped to respective similar-function steps in a second software application of a second web site. The mapping for each step in the first software application includes associating both each step in the first software application and the respective similar-function step in the second software with a respective task. Measures of performance of each mapped step in the first software application and measures of performance of the respective similar-function steps and of other steps in the second software application are determined and included in a report. A measure of performance of the first software application and a measure of performance of the second software application are included in the report.
