SUNNYVALE, California: Yahoo! has unveiled improvements to its search engine as it strives to dent Google's seemingly overwhelming market lead.

Among the enhancements the web giant is trumpeting is a drop-down menu that suggests related information for deeper exploration of search topics - but only when the user asks for extra help.

Other new features include integration of multimedia results such as video, audio and photos, including pictures from Yahoo!'s Flickr photo-sharing site.

Investors, however, appeared underwhelmed. Analyst Jim Friedland believes "the company is following faster, not innovating".

His adds: "We continue to believe that Google will achieve a global-search market share of at least 90% over time, marginalizing Yahoo! and Microsoft."

  • Meantime, Yahoo! is believed to be mulling the sale of its "underperforming" European online shopping comparison website Kelkoo, which it acquired in 2004 for €475 million ($673m; £330m).

    The company remains zip-lipped on a possible disposal of the Paris-headquartered site but a spokesman did say: "One of the priorities we have identified is improving the performance of Kelkoo. We are currently identifying the right leadership and team structure to achieve our business goals with that organization."
