> Contextual advertising works It would, unfortunately advertising agencies have showcased advertisers that they can hijack focus of an average website visitor with rich graphics irrespective of the context e.g. Say toothpaste ad on a tech blog; And the toothpaste company doesn't care as long as they get a click(even if the conversion is abysmal). Other side of the story is that the tech blog would find it very hard to get a proper referral link for PC parts they're covering for contextual advertising unless they're of considerable size. Where as getting a banner ad to display what ever it wants is just usually couple of clicks. As a result, whole Internet is full of rich graphics built by and built for these advertisers making simple text based readable websites an endangered species; Further making the lives of those with accessibility needs miserable.
