I'm having difficulty tracing how certain ads are served.
For example, on LA Times, there are google ads sure, but there are others that are not so obvious.
Live Http headers show r1.ace.advertising.com, then ad.doubleclick.net.
I've emailed advertising.com and get no answer.
I have visited doubleclick.com but don't see any obvious way to buy these ads that I see displayed on various online newpapers and mags.
I have used adsonar, but that is very straightforward on the websites themselves.
- Any clues as to how to trace the origin of ads that are online and not obvious?
- Anyone use doubleclick?
