Online personalization company Yodlee and search engine AltaVista Co. Monday agreed to deliver clients a co-branded service that lets users view personal account information.

Financial terms were not disclosed.

AltaVista is the first network to use Yodlee's Web Personalization Platform, which offers windows to bank accounts, investments and shopping orders among other things. Also, AltaVista users will be able to access their personal data on mobile and wireless devices through the Yodlee2Go software offering, an integral part of the Yodlee Platform.

Yodlee's platform allows partners to customize solutions to their users' needs, such as choosing the categories and sites, the colors and specific features and functionality for users.

"We believe this service offers users the most efficient one-stop shop for all of their personal and online needs through Yodlee's Personalization Platform," said Ross Levinsohn, vice president and general manager of new media for AltaVista.

AltaVista's business did not stop with the Yodlee agreement Monday. The CMGI-owned (CMGI) company launched a new business unit to fulfill information search and retrieval needs facing today's businesses. AltaVista Business Solutions licenses search products that leverage the search engine technology.

The portal provides a scaleable search solution that includes both products and services. The search software products include AltaVista Search V2.3A and AltaVista SDK V2.6, which allow sites to search for information in more than 150 file formats from databases, Web servers and file servers throughout the network.

According to a recent study by consulting firm Creative Good, billions were lost in e-commerce purchases last year -- $2 billion in the holiday season alone -- because the search technology of many sites failed to provide a satisfying user experience. It is AltaVista's belief that in order for Web-based businesses to become successful, they need to convert casual Web "window shoppers" into buyers.
