May 05, 2003Life after death for advertisements?I've been spending a little time trying to figure out how, on this website, people were hitting ads that had expired, and therefore shouldn't be displayed on the screen anymore. I finally figured it out: they are viewing my webpage in the Google Cache, clicking on ads, and leaving little cryptic notes in my logfiles... I was receiving strange entries in the user logs :
I couldn't figure out how adverts could be getting hits when there were none in the system, and therefore none getting displayed. In fact, Google cached some pages with adverts in them and that's where the hits came from, users clicking on these get redirected to my redirection page (!) and the log records this as a hit. Since the adverts are still in the system, they then get shunted to the right place.
