Chase Had Ads on 400,000 Sites. Then on Just 5,000. Same Results. by The New York Times via VFTW. I wonder if they will also stop advertising on sites like mine due to the type of content we post. I’m really surprised that credit card issuers don’t do more long term tracking (e.g at the moment they mainly focus on approved applicants, rather than how profitable each approved applicant ends up being). There has been some switch to long term tracking, but surprised there isn’t a lot more.
