Bill Gates says Microsoft (NASDAQ: MSFT) will chase the search business whether it buys Yahoo! (NASDAQ: YHOO) or not. He says that the company's mighty tech arsenal will allow it to improve the efficiency of its search results and that it can take a larger share of the market based on that alone.

"We can afford to make big investments in the engineering and marketing that needs to get done. We will do that with or without Yahoo," said Gates in an interview with Reuters. For a very smart man, Gates sounds dumb.

Microsoft currently has about 11% of the search market in the US. Its global piece is even smaller. Not only does Google (NASDAQ: GOOG) have a much larger share, it is also improving its technology as quickly, if not more quickly, than Redmond.

Gates may have been asked to make his comments to signal to Yahoo! that it will not raise its offer. It only needs the search portal so much. It can reach its goal on its own.

But behind closed doors, Gates knows better.

It is hard to imagine that Google's (NASDAQ: GOOG) share of the search market in the US could get much larger, but in each month it seems to make further gains.

Google piece of search queries increased to 57.7% in November compared with 55.5% in October, according to data from Nielsen Online cited by The Associated Press. . For the big search company to move up that way. Yahoo! (NASDAQ: YHOO) and Microsoft's (NASDAQ:MSFT) pieces of the pie had to move down. And, they did.

The flip side of Google's monthly success story is the talk of Yahoo!'s failure. Its share of November searches dropped to under 18%. At the rate it is failing, the number could be less than 15% by the end of the year.

The story about the failure at Yahoo! is now as old as the hills, but what may happen to its stock price is another matter. Its shares are now below $24 which is near its 52-week low. Search is not all of Yahoo!'s business, but it does rely on the feature to bring in much of its traffic and revenue.

At a 15% share of the search market, what is Yahoo! worth? Certainly not $24. Perhaps below $20. That could be a 50% drop in two years.

Ask.com, the web search service that is owned and operated by IAC/InterActive Corp. (NASDAQ: IACI), has been fighting the good fight over the last year with a television, print and radio campaign that practically begs consumers to give its search service a try instead of just defaulting to Google Inc. (NASDAQ: GOOG)

While Yahoo! Inc. (NASDAQ: YHOO) and Microsoft Corp. (NASDAQ: MSFT) are also competitors, Ask.com has chosen to focus its competitive stirrings directly on Google.

I use Ask.com every day, as some of the features the service provides are actually more intuitive and easier for my line of work that what Google can provide, something I wrote about about this time last year. But I use Google the majority of the time, like most web searchers.

Ask.com's search market share really has not made significant strides against Google lately, although it has grown a bit. The company is again targeting Google with a revamped and enhanced search page that is designed to get more people using Ask.com's service.

In fact, the services that Ask.com is now highlighting look like they were taken from Google's recent "Universal Search" play book. While it's a joy to use Ask.com every day, the company's battle to win more market share will never be easy. Google's brand recognition alone will be nearly impossible for any competitor to topple.

That's not to say Ask.com can't make gains (nor Yahoo! or Microsoft). The only unfortunate part is that even building an equal or semi-equal product does not guarantee customers will dump a competitor to come to you.
