physics - 5:28 pm on Sep 23, 2009 (gmt 0)  Do they need opt-in
polls to tell them "measure consumer attitudes and purchase
intent from display advertising that has appeared on the site."?
Is it not true that people say one thing on a poll but then go
do another? Seems like they could get this information in a more
direct way based on actual user interactions with the ads. A
better approach might be to offer advertisers a JavaScript
tracking code they could place on their page (similar to Google
Analytics) to help them measure the actual effectiveness and
conversion rate of ads. Then they could study that data in
aggregate to gain a "better undertanding of how Web content and
advertising affect consumer behavior."  Thread source:
