The overall look should match the rest of the website.
SOME WEBSITES WE LIKE: http://www.airbnb.com
This website has a beautiful image at the top of the homepage that changes. The search is very simple, yet very functional. The text above the search boxes clearly explains the main purpose of the website. The smaller boxes toward the bottom of the page are neat and easy to read. We also love the changing places (listings) in the bottom right corner of the large image. http://www.cycletrader.com
This is one of our competitors. While we do not like the search boxes on the homepage, we really like the 'Featured Motorcycles for Sale near..." section of the homepage. The featured bikes are displayed based on the user's location and he/she can scroll left or right, which is very cool and relevant. We do not like the fact that the homepage is too cluttered. We believe in clean and simple designs. http://www.ideeli.com
This homepage has a very clean and functional design. It is easy to search for items. The menu bar at the top of the page is simple, yet very easy to see.
