Do you know companies actually send data to Google (and Facebook) to target ads?

Its common and help companies target clients with ads on the internet in general (YouTube, sites, etc).

It works like that:

- The Chemist wants to sell things online or physically.

- They pay google for ads for their products on sites related to its business lines or keywords about its niche.

Google then show their ads for people in general, people interested on those subjects or to people visiting sites about those subjects.

Interest is determined by search history and navigation (every google ad in a site (chemist or not) help google know you were there).

Then the chemist want to target past customers with more specific ads (like reminding people of items in theirs carts):

- They send google ads information about clients and past physical or online purchases / interactions.

Google then match the user with its own database and connect the sent data with its own data.

- Now the Chemist benefits from the google (because google can find you online)

- Now other google clients benefit from this data (because now your google hidden profile is more accurate about your interests and habits)

- Now Google benefits from that because it can use the purchase data to hone its models about ad-to-spend.

The chemist also want to pay google a fraction of the purchases if the client saw an ad.

- Google uses information sent in realtime by the Chemist and other companies, model this data and determine which people, sites and subjects have a bigger probability to turn an Ad into a sell.

I have myself done that in the past and Facebook was quite accurate at turning ads into course subscriptions.
