I used to think they don't but even when you don't realise it adverts do often play a role subconciously. Like if you've seen something advertised a lot you know the brand so it doesn't seem like some cheap off-brand (though personally I usually buy cheap off-brand products anyway). But I think adverts mostly make you want to buy something (like you're thirsty and see a juice advert and want juice) rather than making you choose the specific brand when looking for something you want

Nope, positive reviews on the product do. I always do my research.
