It's hard to argue with the recent success of Ask Jeeves (NASDAQ:ASKJ). The shares have quadrupled over the past year as the company coasted through 2003 and is kicking off 2004 in grand fashion.

Last night, the Internet portal posted appetizing first-quarter results. Earnings per share more than tripled to $0.23 as revenues soared 73% to $39.2 million.

Next month, the company will close its acquisition of Interactive Search Holdings, a move that will ultimately double its market share. That's significant because virtual real estate has become the name of the game in paid search. That's right, those familiar eyeballs the dot-com market befriended matter again.

And paid search is the place to be. While the market anxiously awaits Google's debut, other companies that have cashed in on sponsored search have thrived. Yahoo! (NASDAQ:YHOO) leads the way, especially after acquiring pioneer Overture last year, but Infospace (NASDAQ:INSP) and Stocks 2004 recommendation (NASDAQ:FWHT), among others, have more than doubled off last year's lows.

Terra Lycos (NASDAQ:TRLY) and LookSmart (NASDAQ:LOOK) have been laggards, but even these troubled mutts have been doggie paddling in rising waters over the last six months. Even bellwethers Microsoft (NASDAQ:MSFT) and Time Warner (NYSE:TWX) are cashing in on the paid search phenomenon; however, both are too diversified and troubled elsewhere to be coming along for the ride.

For the year, Ask Jeeves is looking to produce $255 million in revenues. It is also guiding investors to expect $0.75 a share -- or a whole dollar on a pro forma basis -- in earnings. While the stock's gains make it hard to call it a bargain at these levels, the paid search tailwind is here to stay. Be on the lookout for any unjustified dips as a way to ride the waves.

Are the Internet stocks overpriced again? Are these reasonable valuations or do you smell bubble? How will the industry's top dog -- Yahoo! -- compete against Google? All this and more -- in the Yahoo! discussion board. Only on
