Surely that is counter-productive for the advertisers. The time to show
the adverts is while you are still looking prior to purchasing. Once you
have purchased, especially an expensive item, you are unlikely to
purchase an alternative in the immediate future. So once the purchase
has been made, advertisers of alternative products have missed their
opportunity. So while you are investigating the market, adverts for
similar products are appropriate, but once the purchase has been made it
would more appropriate to target adverts for accessories and other
items/services related to what was purchased. This applies equally to
goods and services. So for example while someone is researching
holidays, adverts for package holidays, resorts, price comparison sites
etc might be appropriate. Once the holiday has been booked, sending more
adverts for holidays would be a waste of time, but adverts for luggage
and items appropriate to the booked holiday (like sun protection and
swimwear for beach resorts, ski accessories for winter holidays, etc)
would be more likely to lead to a sale.
