Hi,
This is a whole new thing to me; never seen it before.
On Random pages, at the top of the actual webpage, it shows the same amazon
web banner.
See here: http://sam06.tfcph.com/googleadvert.jpg
It doesn't seem to appear on all pages, but appears on websites such as
google and wikipedia.
If it's any help, the link links to:
http://www.amazon.com/?&tag=granoffe...5Y5PN3R0Q864Y&
which appears as an affiliate link?

Kind Regards,
Sam.
