Can anyone tell me how internet browsing sponsored adverts work? An advert for Victoria’s Secrets appeared on my computer today. I have never looked at this website before. I do know however that my H is having an affair, although he Denies it and I wondered If another computer sharing my IP address had been looking at the Victoria’s Secrets website (for his girlfriend not for his wife) would this then promt a Victorias Secrets ad to show up on another linked device??? I know browsing history is tracked so that retailers can promt you again with specific ads but I wondered if this is how it worked??? In desperate need of some hard evidence to pin on him and this might be a good place to start if my understanding of this is correct??
