Websites within the EU are meant to inform users about the use of cookies on their website. Whilst the law raises plenty of implementation questions already, the general consensus is that we must at least display text to the user in some form (usually in a bar at the top or bottom of the page).
My concern is that this causes the same text to be displayed across every page of the site. This question from a year and a half ago suggested including the text in an image or iFrame, but I'd like to think that somebody has come up with a better solution for cookie notifications as they've become such a big part of the web since then. Maybe there's even a HTML5-specific tag that would accommodate this.
How can we display this text across every page of the site without search engines picking this up and thinking it's important content.
