How will the sites fare, is the big question.

While Super Bowl advertisers pay millions to get their television ads in front of over 100 million people in the U.S. alone, are they prepared to actually handle the onslaught of site traffic they hope to generate?

This year, for the first time ever, and because of the growing importance of the mobile channel to business, Keynote is measuring the performance of Super Bowl advertiser’s websites in real time across three screens -- desktop, mobile and tablet -- to see who crosses the finish line first during the most watched television event of the year. The creative is ready. Social media campaigns are already teasing viewers. Come Super Bowl Sunday how will advertisers fare when viewers start clicking on the company’s sites?

Keynote experts will be on hand Monday to share metrics and explain the performance of the real winners and losers of this year’s Super Bowl; the advertisers.
