I'm launching a new bookmarklet (calculator), and have an adsense-ad on it. The ad unit is placed inside an iframe. Technically, the code from my bookmarklet will be locally (at client) added to witchever site the user is on when initializing the bookmarklet, making the ad unit appear in an iframe at this site. I would presume the referrer was the iframe URL. However, the keywords used to display ads seems to come from the site witch the user is at when initializing the bookmarklet. What are your thoughts around this? Is this potentially against the TOS? You can view the bookmarklet here: http://kalkuler.no/bookmarklet.htm, click "Klikk her for forhåndsvisning" or the "Kalkuler.no"-button under step 1. The site is in Norwegian.
Do you have source? I've googled this a bit, the majority of articles and forum posts seem to say iframe is okay.
