When you want to buy something, you google for the price,  places to shop, brands comparison, customer review... all in all, you google for everything you want to know. Googling has become necessary part of our daily lives. For retailers to boost their sales, they spend millions of dollars on advertising above google search results.

The biggest development with search ads is the proliferation of so-called product listing ads, or P.L.A.s. In a departure from its text-based ads, Google started allowing retailers to post pictures, descriptions and prices of products at the top of search results in 2009. This change is profound for brands and retailers.
