I often evaluate manufacturer web sites to rate the effectiveness of their Where to Buy implementation. Coby Electronics has done an excellent job of creating a simple flow for users. Combining clear navigation with a well designed site, Coby makes it easy for people to buy.
I use eight best practice criteria to evaluate each web site. These include: number of clicks to get to a product page, showing MSRP, link design (button or text), link text (active or not active), button position (above or below the fold), button positioned close to the product image, button contrast (color, size, white space) and the number of buying options on the page.
Using these criteria the site is rated on a 1 to 10 scale, where 10 is excellent. Coby rates a 9.0. The only thing Coby is missing from their design is a MSRP or ERP to give the user some idea of the price point of the product.
