GOOGL is my largest holding. I always click the ad in Google when I'm going to a site to buy something. 
  
 Want a new Adidas hoodie? Search 'adidas' on Google, click the sponsored ad for their homepage, buy hoodie. Adidas gets data that says their Google ads convert, Adidas spends more with Google, my shares go up, hoodie pays for itself.

I just bought some shares in Adidas cus u told me you bought a hoody so they must be popular.
