How Google ‘Buy Now’ buttons will affect search experiences

Late last year, Google informed that they are going to put ‘buy’ buttons on their search page. I wonder how it’s going to affect billions of people who visit the Google search page every year.
Maybe they thought about this because social media giant Facebook too had said something about creating their own special buy now buttons.

This could be the next step in changing the way internet forever.

How do you think this will affect your Google search experience?
