Last Friday, the price of its share Google rose 16,8%, adding nearly $68 billion to its market value companys.
The increase in the share price, which sent the Nasdaq composite index to an intraday record, came a day after Google's announcement that was much better than expected for the first time in six quarters.
The earnings from the company's share price increase were greater than the total capitalization of Caterpillar Inc.
Google's shares reached the record price of 703 dollars, valuing the company at 471,50 billions of dollars and confirming its position as the second most valuable company in the world after Apple Inc.
At the highest target price, Google will have to be valued at 545 billions of dollars, while Apple at 740 is worth billions of dollars.
But why such a big increase in the share price? Google said Thursday that clicks on YouTube grew 60 percent in the second quarter of 2015 and that the video service had the most mobile viewers ages 18 to 49 of any cable Internet provider in USA.
Of course, the fact of increasing clicks means money in itself (see advertisements), something that did not go unnoticed by those directly concerned.
So Google goes far beyond Facebook and leaves investors in no doubt about how much they should invest.
