Do you ever click on the Advertising on the top of your GMail Inbox? Did you ever realize these are targeted on the content of your emails? Yes Google’s matching advertising to what you write or what your family and friends have written in emails sent to you. And the targeting is getting better, see here the targeting for Baby & Kids clothing just two weeks before my wife and I expect our third baby. You know it, if it’s free, you’re probably the product being sold.
