Analytics Clients Gain Additional Deployment and Pricing Options

San Diego – April 5, 2007 – Visual Sciences, LLC, a wholly owned subsidiary of WebSideStory, Inc. (Nasdaq: WSSI), a leading provider of real-time customer intelligence solutions, today announced it will now additionally offer Visual Site® as an on-demand service with CPM-based (cost per thousand impressions) subscription type pricing. Visual Site delivers real-time intelligence about the use and performance of large and complex Internet sites, portals, services and systems. Through integration with third-party business systems and data warehouses, Visual Site is the only solution that can deliver a real-time holistic view of the performance of the Internet channel in addition to optimizing the Web site experience. With this new subscription pricing option, prospective Visual Site On-demand clients have the ability to purchase on a CPM basis.

In a February 2007 report titled, “Measuring Rich Internet Applications”, Forrester Research wrote, “Firms want ad hoc analysis tools that let them explore Web usage data in many different ways. Their need to analyze RIA [rich Internet application] data – which can be very application-specific – will accelerate demand…Visual Sciences, with its flexible, event-based data architecture and powerful analysis capabilities, will appeal to the highest end of the analytics market.”

“Visual Site is the most innovative and robust Internet channel analytics solution available,” said Jim MacIntyre, president and CEO of Visual Sciences and WebSideStory. “With this new subscription-based pricing model we are opening the door for more companies to take advantage of Visual Site’s unrivaled ability to quickly answer the hardest and most valuable questions about their Internet channel’s performance so that they can implement optimizations and see improved results sooner.”

Visual Site On-demand requires page tagging and allows optional advertisement and other event tagging, including the tagging of streaming media, RIA and generally any type of client or server-side event that can be instrumented. Clients may then use Visual Workstation®, an interactive visual analysis and reporting application, which provides real-time multi-dimensional metrics analysis, dynamic segmentation, advanced data visualization and other ad hoc analysis capabilities. In addition, clients may design any reports they like on the fly and see them updated on an ongoing real-time basis, or have Visual Report™ publish them through e-mail or into its own or other corporate reporting portals. Visual Site offers clients a holistic real-time view of their Internet channel, including any marketing and visitor/customer activity at a level of granularity that provides professionals with the necessary intelligence to make profitable strategic and tactical business decisions.

Other Visual Site capabilities include:
• Ad hoc interactive data analysis and visualization with unprecedented speed
• Unlimited reports through its WYSIWYG report design interface
• Lifetime visitor-level metrics and an unlimited number of dynamic segments on-the-fly
• The ability to define, use and visualize an unlimited number of custom metrics
• Controlled experimentation to learn through iterative hypothesis, testing and analysis
• Advanced data integration capabilities allowing inclusion of data from other channels
• The ability to easily output visitor-level data to marketing systems and data warehouses

This new Visual Site On-demand offering enables clients to optimize the performance of their Internet channel, without the need for significant investments in internal infrastructure. Though Visual Sciences continues to offer its software products for in-house operation, Visual Site on a subscription basis requires only tagging. Everything else is run by Visual Sciences on an outsourced basis. In the future, if a client requires, Visual Site can be migrated in-house as is sometimes demanded by corporate security policies or other integration or operational requirements.
