Well, they could just use common sense: a washing machine is something people look at when the old one broke down or moved house: they need it so they are likely to buy one asap. Show it a week and then stop. Laptops are similar: makes no sense showing it for months, and that is what happens now. Even if they have the sales data, it is not connected to the ad data (bought a laptop from a big chain here this week: will get ads for that laptop from the same chain for months) so common sense should work fine for now. If the ads appear around the days I am looking for the article, I even might click on them. Now that my brain knows all ads are irrelevant because they are outdated things I already have, I just do not see them anymore.
