We used cards to discover how different people would lay out a search menu for a web page. The website we were investigating was DID Electrical, a retailer of white goods and consumer electronics. We wrote the individual item descriptors, (e.g. Fridge, Cooker, TV etc.), onto individual cards. We then asked somebody to lay out the cards as they would expect to see them laid out on a website. Following this we compared what the user was expecting to what the site actually looks like. If there is a consistent and significant difference highlighted over many iterations of this exercise, it would indicate that it may be prudent to align your website with what your users are telling you that they expect to see!
Image #1 is the way the website is currently laid out. (long and messy?).
Image #2 is how the users expected it to be!
