Have you ever been wandering around the internet and been surprised to find the same advert following you? If you have, welcome to remarketing.
Or maybe you looked at an online product and then, later that day, saw a discount advert in your social media feed. Or you clicked an advert in Facebook, and then found it at the top of your searches.
Yup – those are remarketing too. Which sounds just a little less creepy than its former, but now less favoured name: retargeting.
