Reason being is because there is no or very little effort, time and personal creation to it. Good design and coloring. Things need to match well, coloring too, same design theme throughout your site. Have it linked on every single page so people don't get sucked into one deep hole and can't escape to the homepage unless they hit 'back' 12 times. NO excessive use of cartoon clipart, exspecially if the images don't pertain to your site at all.
Any site can go for it whether it be business or homepage.
This Award is for Excellence in website creation. No all banner pages. Must of some content to it. Finally, don't hate me or feel bad if your site doesn't win. Alot of people apply for this award and sometimes, it's very difficult because there are so many great sites out there.
