It's very easy to look at Alphabet's financials and see that there are no preferred or common shareholder dividends. Since you haven't done that, I presume you are genuinely curious.
There are probably a lot of reasons that people invest in corporations that don't pay a dividend. The "most obvious" is that you believe the company is growing. The organization will reinvest in itself -- instead of paying you a dividend -- and increase share price to a degree greater than you would have gotten with a quarterly dividend.
