You’ve nailed it completely. They use your info and mark you as interested in that product, as well as put you in the pool of people visiting that site and the interests associated with them, and you’re likely showing up in LLA audiences that the other companies have running. You know, on any ad you can actually click the 3 buttons and press ‘why am I seeing this ad? ’. It will show you if they uploaded your email, or if you’re on a LLA or if they’re targeting ‘camping’ for example. All the best!
