Retargeting

Lot and lot of hype is there on Retargeting on internet. I am trying to clear some of the myths, some of the confusion and ways to implement it.
what is targeting?
It is connecting the right user for the right product.
What is retargeting?
connecting the same user again for the same product or for the different product which might be of interest to the user.
How do we implement this?
Implementing it on internet is very easy, internet is about measurement, analysis and controlling.
Measurement, What need to be measured?
We measure the activities of the internet user.
How do we do this?
We measure it by the help of cookie. Cookie can tell us, where all the internet user has visited, clicked on which all ads. Once we know his interest, bang we can retarget him.
How do we analyze this data?
suppose the user clicks on Matrimonial ad, and then he go ahead and gather the info about the product. but he never purchased the product.
how do we analyze the data for retargeting?
we know his interest, and his willingness to buy a product. we can now retarget him for the same product again and again, till the time he don’t purchase it. Wow we have a sale now. and sale is what we wanted.
Here a little more we can add to this. since he has already purchased a matrimonial service, what more can we offer? can we offer him a loan. Yes we can, since he is getting married, he might need some finance. Lets offer him a personal loan.
and bingo, right on the bull’s eye.
Amazing, now this is where technology helps. we do this with the help of a pixel and a cookie, and some servers.
