My biggest issue is, i can't remember when i clicked on a ad and was not closing that tab asap. It would be really nice to see those people buying to understand it more. Amazon for example still shows me washing machines after i purchased one through amazon. But that feature is still here on a high traffic user landing page! Perhaps it matters for products which are clearly build for a very specific target (like a startup selling a shopping service to 30 year olds which work all the time) but there might also be a lot of standard products which everyone would buy? Dog food, dog toys etc. Also i often enough see companies paying (at least those are ads) for there own name. When you enter 'Miele' (well known german company for washing machines and other stuff). You get an ad for miele.de but miele.de is already the first hit. The same when googling 'Samsung S9'.
