Ads: Why click on something you’ve already bought?
It’s a curiosity – how has the price evolved?
The client wants to know: What was written in the description? What comments did others leave about the product?
It is much harder for them to recommend a relevant new product than to get you on the site with the same product.
So, you know the product, it’s familiar to you, you want to see if you’ve made a good deal. And once they get to the site, they’ll do everything they can to click on something else.
The important thing is to come back first.
