Since a lot of members here opt for doing their own web sites, there is a very good chance that you are making a common error in your design. But hey, a lot of pros do too, so don't feel bad. Which also tells you that even if your site was developed by a pro, you still want to check this out.
Logic would tell you if you want to make something stand out on your page, you make it stand out. Usability tests prove that logic is wrong. This isn't new information, but if it's new to you, it might explain why your visitors are "missing it" when they view your site.

Take careful notice that it's not just the big red numbers that killed this page, it's some stuffed shirt designer thought "population clock" sounded more creative than "current US population."
It reminds me of all those sites I review here that say something like, "We operate only with the utmost integrity." Sure that sounds nice, and I'm not trying to be too critical, but if you realize how ineffective that is and correct it, you will see much better response (i.e. profits).
What stood out to you in this study? How can it help you? Have you considered the importance of eye tracking and usability before? Did you even realize they did
eye tracking or did that term sound like something only your doctor would care about?
