Usability evaluation (UE) is a methodology for measuring these usability aspects of a system's user interface and identifying specific problems with the interface [Dix, Finlay, Abowd, and BealeDix et al.1993, NielsenNielsen1993]. Usability evaluation is itself a process that entails many activities: specifying evaluation goals, identifying target users, selecting usability metrics, selecting an evaluation method and tasks, designing experiments, collecting usability data, and analyzing ...

Abstract: A quantitative analysis of a large collection of expert-rated web sites reveals that page-level metrics can accurately predict if a site will be highly rated. The analysis also provides empirical evidence that important metrics, including page composition, page formatting, and overall page characteristics, differ among web site categories such as education, community, living, and finance. These metrics concern page composition (e.g., word count, link count, graphic count), page ...

We present preliminary findings of a quantitative analysis of several attributes of Web page layout and composition and their relation to usability. Additionally, Web site home pages were found to have measurably different characteristics than other pages. For each Web page, we computed 12 quantitative measures having to do with page composition, layout, amount of information, and size (e.g., number of words, links, and colors).

In the paper I discuss the role of quality models in the development and maintenance processes of websites and show how they can be based on existing guidelines and web-site testing tools. Quality models can enable development and maintenance processes that consistently achieve high quality standards based on standardized data acquisition and measurement methods. For example user testing, heuristic evaluation or automatic webtesting systems.

Average # Site Internal Links Per Page How many links does an average page on a site have on it? Average Page Weight How many pages on the site link to a specific page? In summary, we want a low minimum span, low number of internal links, low average page distance, low average page weight, and low average page size per page on the site.
