There have been concerns that the rate at which people clicking on the text ads next to Google (NASDAQ:GOOG) search results has been falling. These concerns caused spirited debate before the company's last earnings report and may have even pushed the firm's stock price down. But earnings were excellent, and much of the fear went away.

Now it turns out the Google ads are doing better and better, and clicks on ads at rivals are falling. The Wall Street Journal, using comScore (NASDAQ: SCOR) data, reports that Google's performance improved in April and "Paid clicks for Microsoft Corp (NASDAQ:MSFT) and Yahoo Inc (NASDAQ:YHOO) meanwhile declined during the month, according to the data." The paper reports that Google's performance in the U.S. was 20% ahead of expectations.

Good for Google, but very bad for its two chief rivals. The information indicates that even if Microsoft buys Yahoo!, the combined operation will have a much smaller market share in search than Google, and its advertising will perform worse. If Microsoft and Yahoo! stay separate, their uphill battles could face extremely long odds.

From all the data available, Google's search technology brings back better results for consumers. Its technology for matching ads to searches also appears to work much better. The fight for the domination of this critical portion of the internet is over. The only question is whether the second and third place firms can make money long-term.

The deal for Yahoo! (NASDAQ: YHOO) to allow Google (NASDAQ: GOOG) to sell text ads on the portal's search pages may happen more quickly than most analysts believed. According to The Wall Street Journal, "Yahoo Inc. moved closer to outsourcing its search advertising to Google Inc. after an initial test of the system yielded what the two firms deemed positive results."

The partnership could add several hundred million dollars of revenue to Yahoo!'s annual numbers. Most observers believe that regulators would be troubled by the two largest search companies joining forces.

The news still begs that question of whether any deal can be better than Microsoft's (NASDAQ: MSFT) offer to buy Yahoo! for over $29 a share. The first offer was at $31, but Microsoft's shares, part of the payment, have declined since then.

Yahoo!'s actions to run away from Microsoft seem to go along the lines of trying to stay independent for the sake of being independent. In other words, the company has no answer to the question of why investors are better off if Yahoo! stands alone.

Since no one other than Microsoft wants to buy the portal, the answer is that Yahoo! has lost all options to defend its present strategy. A deal with Google does not, in any way Yahoo! can explain, make the company worth $30 a share.

Google's (GOOG) shares continue to be stuck below $500 where they have been since late February. Part of the reason for the fall is that comScore data showed that the number of people who clicked on ads at the big search engine was weak in January.

It looks like the stock will drop again as "click rates" for Google ads rose only 3% in February when compared with the figures for the same month last year. According to MarketWatch: "Google reported 25% growth in paid clicks in its fiscal fourth quarter ended in December. But comScore data released last month showed flat growth in Google's paid clicks in January." Now, investors can ponder another piece of bad news.

The easy answer to the Google data is that a recession is slowing down advertising activity everywhere. Google carries millions of ads in its AdSense program, so it would make sense that it should suffer some fallout.

But, the answer may be more troubling than that. Readers of Google's search pages may be discovering that the text ads next to the listings are from marketers trying to take advantage of people looking for information by clogging pages with related messages. As more people understand the system of targeting based on search results, fewer are willing to be sucked in by companies trying to reach them due to their behavior.

If the Google system of matching ads to search results is putting its customers off, that would be worse news than the effects of a recession.
