Mostly no, it does not. Actually there is nothing wrong with targeted advertising, products and ads are meant to target specific people in its nature. But online advertising are a scheme for tech companies to make money. Adtech was created to make the buying and selling of online advertising so much more efficient. Today, about $350 billion dollars is spent on online advertising. 70%+ of it is bought programmatically…
- Products and services are make to make money for their creators. They generally try to achieve that by creating something of value others will buy. So this isn't really an argument for or against it. A Prius works and it is a scheme for Toyota to make money.
- The fact not every ad is viewed doesn't mean it doesn't work. It's just the nature of the delivery. It could be a problem or inefficiency at least, but presumably it's factored into pricing. If one company figured out out how to reduce that waste, they should be able to charge more or take more market share.
Not to say it does work, but your post hasn't explained how it doesn't.
