A little insight into why bad ads (like Coach) are happening more often
I work at a company that routinely is the top 5 spenders for Meta/TikTok/Youtube. Everything in advertising basically falls into a funnel (awareness, consideration, conversion). Success is measured for conversion ads by how many people bought products from them via links, clicks, etc. The problem with awareness ads is that they are much harder to measure. Advertisers will let you see the basics like watch time, which will show how much the viewer watched on average before clicking away. But what a lot of advertisers really care about is called a Brand Lift Study, which these advertisers give us if we spend a certain amount. This is what those questionnaires get wrapped up into that you see on YouTube (click the following brand you recall hearing about, etc). The reason why every ad has now become the most loud, fast pace, flashing, stimulating thing imaginable is because these are the ones that ON AVERAGE (talking about 10/20/50 million views) result in the best results for questions like, which brand do you remember seeing an ad from in the last week. Because when Coach plays the ad that screams "LEFT FOOT RIGHT FOOT LEFT FOOT RIGHT FOOT" over 100 times to you in a month, you will definitely remember that coach was serving you ads.
The problem is that brands basically only care about ad recall and unaided awareness in their awareness assets, they dont care about intent, affinity, trust, etc. Higher results on a BLS -> more brand spend with the platform -> platform auto optimizes to force the most "efficient" ads to you -> higher results on the BLS, cycle repeats, ads get louder, more irritating, and you never, ever escape it.
This ultimately ends with a blank screen with a logo on it flashing 10 times a second while a voice screams "MCDONALDS"
