I saw this ads on my site today, The first ad, looks like a video, The second ad is asking the user to click there.. hmmm... creative ehh.
But the "Click here" was put there by the publisher, not by a site owner looking to attract an untoward click.
That is funny! They don't allow that you place a img beside the ads encourging for clicks, but they do it themselves?
Maybe they see using varied types of ads will have greater user interest and reduce risk of ad-blindness.
