I searched products like “YSL wallet”, “Handy.com” (a home cleaning service provider website), and “mac air”. Two of them (“YSL wallet”, “Handy.com”) “magically showed up at the right hand side on my Facebook page. They are quite targeted to my search and browse history. As shown in the picture below, one of them show me the picture of the wallet, discount information and number of people like this. The other show me an attractive price to get the cleaning service.
Overall, I find the ads are quite effective. The discount, visual image and attractive price all attract me to click and buy the products.
