This from the Official Google Blog earlier this week:

"But there’s so much more that Google can do to help you ..... We can provide more relevant ads too. For example, it’s January, but maybe you’re not a gym person, so fitness ads aren’t that useful to you. "

I think the era of optimising our websites to attract the right ads is over. Ads are becoming more and more "personalised" just like Search results.
