Web analytics is the process of analyzing the behavior of visitors to a Web site. The use of Web analytics is said to enable a business to attract more visitors, retain or attract new customers for goods or services, or to increase the dollar volume each customer spends.

Web analytics is often used as part of customer relationship management analytics. The analysis can include determining the likelihood that a given customer will repurchase a product after having purchased it in the past, personalizing the site to customers who visit it repeatedly, monitoring the dollar volume of purchases made by individual customers or by specific groups of customers, observing the geographic regions from which the most and the least customers visit the site and purchase specific products, and predicting which products customers are most and least likely to buy in the future.
