New way for Google to get conversion data on products: Google Trusted store purchase protection program.
I just bought something online, went straight to the merchant website, did not go through Google, as the product was recommended by a colleague. As you can see from the screenshot, Google offers me free purchasing protection. Great, the catch is, my email address will be shared with Google, and I bet a lot more information as well.
I paid with Paypal, but this is a nifty way for Google to get more data on my purchasing behavior.
Damn you Google for being this smart!
And here is how the program works:
From the page (emphasis mine):
"After completing a purchase with a Google Certified Shop, most users will be offered the chance to opt in to free purchase protection from Google for that order. At this time, purchase protection is offered on a per-order basis, and only at the time of purchase. If you opt in, then the merchant will share your order information and email address with us. We’ll send you an email with the details of your order, the merchant's contact details, and a link to contact Google in the event of any issues."
Free Google Purchase Protection, You Pay With Your Data
Remember; if it's free, you're the product being sold... aka your data!
