I've clicked retargeting ads a few times, if they're offering me an abandoned cart coupon ("finish your order at our store and save 10%"). I've worked in ad tech in the past, and retargeting ads (ads that show products you've previously viewed or expressed an interest in) have extremely high clickthrough rates.
I saw an ad in Instagram reels around a week ago for a Chinese company that makes big LED signs like you see at the front of stores like Safeway or Best Buy or whatever. Not interested in the product, but I was intrigued because the guy in the ad was Chinese but had a Texan accent. Turns out he uses a different accent in each of his ad videos. That was amusing. I did click the ad to see the quality of the product.
