But <i>perfect</i> advertising is when you're looking for a car, and you get presented with information about a (more expensive) car that you buy, but that you wouldn't have bought if you spent time doing the research yourself.<p>This is a worse outcome for you, but a better outcome for Google and the manufacturer.<p>I'm not sure if this is possible, presumably if there is something that would convince you to buy it, enough research on your part would hit the same thing and you would buy it anyway - in that case it would be the same as your suggestion - but you wouldn't be doing research on "what's the most expensive car I could possibly convince myself to buy", you would be researching "what's the cheapest" or "the best form/function/cost trade".<p>It still seems like good search results are what you'd want when buying a car, and adverts are what you wouldn't want.<p>What would it take you to get into a state where you skip researching a purchase and take the first advert Google shows you, confident that it would be close to what you'd have found anyway?
