Architectures of Information

The third major set of user experience choices Anu and her team have to make relate to the structure—or architecture—of the information delivery system itself. If that system is an eco-label on a product, how will that eco-label be designed? What will it look like? If that system is a database, how will users access the information through it? What fields will they be able to search? Given that the EEPAC Dataset focuses on websites, in this section I focus on the architecture of those websites. How are they structured, and how easy is it for people to find relevant information on them? Specifically, how many clicks (and how much time and effort) does it take for them to find important information about these programs on their websites?

The average number of pages on these websites is 9.4, with 38 percent having ten or more pages, 42 percent having between five and nine pages, and 20 percent having fewer than five pages. Less than 2 percent have only one primary page and approximately 25 percent have only primary and secondary pages (i.e., pages that are one click away from the homepage). The remaining 73 percent on average have five tertiary pages (i.e., pages more than one click away from the homepage); the highest number of tertiary pages per case in the dataset is fifty-six (Rainforest Alliance). As figure 5.5 highlights, approximately one-fifth of all the codes were found on the primary homepages of the sites, half on secondary pages, and one-third on tertiary pages (pages two or more clicks away from the homepage). Approximately 20 percent of the cases have a majority of their codes on their homepages, 47 percent have a majority of their codes on their secondary pages, and 20 percent have a majority of their codes on tertiary pages (codes were more evenly spread across the page levels in 15 percent of the cases). Over 40 percent provide information in at least one PDF file on their website, which is higher than the statistic noted previously because this includes all PDFs, not only those that include product or company evaluation data.

Figure 5.5 Coded information location in website structure (by percent of codes). Note: Figure shows the proportion of coded text segments that were found on the primary webpage, secondary webpages (pages one click from the primary webpage), and tertiary webpages (pages more than one click away from the primary webpage). Error bars indicate 95 percent confidence intervals for each sample proportion.
