One of our good clients The Weather Channel were invited by MarketingSherpa to do a case study on a landing page optimization campaign we did with them. This was a really interesting page with a lot of great learnings and obviously with that high of a lift, it was very successful. Check out the case study here and make sure you look at the creative samples.
One of the biggest things was that the flash banner out performed the static banner, which best practices typically argue against using flash banners. Not only did it out perform the static banner, but it was one of the most influential items on the page.
