The Iframe Tax: The Iframe Tag versus the Javascript Ad Tag | CPM Advertising : CPM Advisors

Rob pens a post that will probably interest only the few of us who are  familiar with the online advertising business– it’s about the differences between javascript and iframe ad tags.  The most interesting piece for me was this bit about Amazon using iframes:

Now there are exceptions. Some publishers like Amazon.com that work with ad networks grudgingly, purposefully put their ads in two layers of iframes to hide their origin AND to stop unscrupulous partners from “stealing” shopper-related data from their pages presumably – but as my other writings would attest I believe that the “sell the same stuff for different prices” world of online publishing will come to an end in the next several years and then this kind of good-quality-site-hiding-behind-frames behavior should be reduced – with the caveat that data use practices in a non-iframe world will also have to be more closely looked at, which I think will happen regardless.
