We believe there is great learning potential in education involving shared, student-generated knowledge bases. However, it is not yet clear what architectures are most appropriate for such shared knowledge bases in order to facilitate an effective exchange, collection, organization, and sharing of knowledge. In this paper, we discuss the concepts of " liquid ontologies, " to describe novel, dynamic structures for organizing, sharing and browsing knowledge. Liquid ontologies are flexible knowledge structures that are created by, evolve around and adapt to the learners' interests and allow for a tighter coupling between the learners' interests and the viewing and browsing structure of a knowledge sharing system. We present the key ideas behind liquid ontologies, and discuss these characteristics within the context of OpenD, a knowledge sharing environment we developed and its application in graduate courses at a design school.
Proper design has become a critical element needed to engage website and mobile application users. However, little research has been conducted to define the specific elements used in effective website and mobile application design. We attempt to review and consolidate research on effective design and to define a short list of elements frequently used in research. The design elements mentioned most frequently in the reviewed literature were navigation, graphical representation, organization, content utility, purpose, simplicity, and readability. We discuss how previous studies define and evaluate these seven elements. This review and the resulting short list of design elements may be used to help designers and researchers to operationalize best practices for facilitating and predicting user engagement.
Keywords: Website design, usability, navigation, organization, simplicity
Internet usage has increased tremendously and rapidly in the past decade (“Internet Use Over Time,” 2014). Websites have become the most important public communication portal for most, if not all, businesses and organizations. As of 2014, 87% of American adults aged 18 or older are Internet users (“Internet User Demographics,” 2013). Because business-to-consumer interactions mainly occur online, website design is critical in engaging users (Flavián, Guinalíu, & Gurrea, 2006; Lee & Kozar, 2012; Petre, Minocha, & Roberts, 2006). Poorly designed websites may frustrate users and result in a high “bounce rate”, or people visiting the entrance page without exploring other pages within the site (Google.com, 2015). On the other hand, a well-designed website with high usability has been found to positively influence visitor retention (revisit rates) and purchasing behavior (Avouris, Tselios, Fidas, & Papachristos, 2003; Flavián et al., 2006; Lee & Kozar, 2012).
Little research, however, has been conducted to define the specific elements that constitute effective website design. One of the key design measures is usability (International Standardization Organization, 1998). The International Standardized Organization (ISO) defines usability as the extent to which users can achieve desired tasks (e.g., access desired information or place a purchase) with effectiveness (completeness and accuracy of the task), efficiency (time spent on the task), and satisfaction (user experience) within a system. However, there is currently no consensus on how to properly operationalize and assess website usability (Lee & Kozar, 2012). For example, Nielson associates usability with learnability, efficiency, memorability, errors, and satisfaction (Nielsen, 2012). Yet, Palmer (2002) postulates that usability is determined by download time, navigation, content, interactivity, and responsiveness. Similar to usability, many other key design elements, such as scannability, readability, and visual aesthetics, have not yet been clearly defined (Bevan, 1997; Brady & Phillips, 2003; Kim, Lee, Han, & Lee, 2002), and there are no clear guidelines that individuals can follow when designing websites to increase engagement.
This review sought to address that question by identifying and consolidating the key website design elements that influence user engagement according to prior research studies. This review aimed to determine the website design elements that are most commonly shown or suggested to increase user engagement. Based on these findings, we listed and defined a short list of website design elements that best facilitate and predict user engagement. The work is thus an exploratory research providing definitions for these elements of website design and a starting point for future research to reference.
2. MATERIALS AND METHODS
2.1. Selection Criteria and Data Extraction
We searched for articles relating to website design on Google Scholar (scholar.google.com) because Google Scholar consolidates papers across research databases (e.g., Pubmed) and research on design is listed in multiple databases. We used the following combination of keywords: design, usability, and websites. Google Scholar yielded 115,000 total hits. However, due to the large list of studies generated, we decided to only review the top 100 listed research studies for this exploratory study. Our inclusion criteria for the studies was: (1) publication in a peer-reviewed academic journal, (2) publication in English, and (3) publication in or after 2000. Year of publication was chosen as a limiting factor so that we would have enough years of research to identify relevant studies but also have results that relate to similar styles of websites after the year 2000. We included studies that were experimental or theoretical (review papers and commentaries) in nature. Resulting studies represented a diverse range of disciplines, including human-computer interaction, marketing, e-commerce, interface design, cognitive science, and library science. Based on these selection criteria, thirty-five unique studies remained and were included in this review.
2.2. Final Search Term
(design) AND (usability) AND (websites)
The search terms were kept simple to capture the higher level design/usability papers and allow Google scholar’s ranking method to filter out the most popular studies. This method also allowed studies from a large range of fields to be searched.
The literature review uncovered 20 distinct design elements commonly discussed in research that affect user engagement. They were (1) organization – is the website logically organized, (2) content utility – is the information provided useful or interesting, (3) navigation – is the website easy to navigate, (4) graphical representation – does the website utilize icons, contrasting colors, and multimedia content, (5) purpose – does the website clearly state its purpose (i.e. personal, commercial, or educational), (6) memorable elements – does the website facilitate returning users to navigate the site effectively (e.g., through layout or graphics), (7) valid links – does the website provide valid links, (8) simplicity – is the design of the website simple, (9) impartiality – is the information provided fair and objective, (10) credibility – is the information provided credible, (11) consistency/reliability – is the website consistently designed (i.e., no changes in page layout throughout the site), (12) accuracy – is the information accurate, (13) loading speed – does the website take a long time to load, (14) security/privacy – does the website securely transmit, store, and display personal information/data, (15) interactive – can the user interact with the website (e.g., post comments or receive recommendations for similar purchases), (16) strong user control capabilities– does the website allow individuals to customize their experiences (such as the order of information they access and speed at which they browse the website), (17) readability – is the website easy to read and understand (e.g., no grammatical/spelling errors), (18) efficiency – is the information presented in a way that users can find the information they need quickly, (19) scannability – can users pick out relevant information quickly, and (20) learnability – how steep is the learning curve for using the website. For each of the above, we calculated the proportion of studies mentioning the element. In this review, we provide a threshold value of 30%. We identified elements that were used in at least 30% of the studies and include these elements that are above the threshold on a short list of elements used in research on proper website design. The 30% value was an arbitrary threshold picked that would provide researchers and designers with a guideline list of elements described in research on effective web design. To provide further information on how to apply this list, we present specific details on how each of these elements was discussed in research so that it can be defined and operationalized.
3.1. Popular website design elements (Table 1)
Frequency of website design elements used in research (2000–2014)
Seven of the website design elements met our threshold requirement for review. Navigation was the most frequently discussed element, mentioned in 22 articles (62.86%). Twenty-one studies (60%) highlighted the importance of graphics. Fifteen studies (42.86%) emphasized good organization. Four other elements also exceeded the threshold level, and they were content utility (n=13, 37.14%), purpose (n=11, 31.43%), simplicity (n=11, 31.43%), and readability (n=11, 31.43%).
Elements below our minimum requirement for review include memorable features (n=5, 14.29%), links (n=10, 28.57%), impartiality (n=1, 2.86%), credibility (n=7, 20%), consistency/reliability (n=8. 22.86%), accuracy (n=5, 14.29%), loading speed (n=10, 28.57%), security/privacy (n=2, 5.71%), interactive features (n=9, 25.71%), strong user control capabilities (n=8, 22.86%), efficiency (n=6, 17.14%), scannability (n=1, 2.86%), and learnability (n=2, 5.71%).
3.2. Defining key design elements for user engagement (Table 2)
Definitions of Key Design Elements
In defining and operationalizing each of these elements, the research studies suggested that effective navigation is the presence of salient and consistent menu/navigation bars, aids for navigation (e.g., visible links), search features, and easy access to pages (multiple pathways and limited clicks/backtracking). Engaging graphical presentation entails 1) inclusion of images, 2) proper size and resolution of images, 3) multimedia content, 4) proper color, font, and size of text, 5) use of logos and icons, 6) attractive visual layout, 7) color schemes, and 8) effective use of white space. Optimal organization includes 1) cognitive architecture, 2) logical, understandable, and hierarchical structure, 3) information arrangement and categorization, 4) meaningful labels/headings/titles, and 5) use of keywords. Content utility is determined by 1) sufficient amount of information to attract repeat visitors, 2) arousal/motivation (keeps visitors interested and motivates users to continue exploring the site), 3) content quality, 4) information relevant to the purpose of the site, and 5) perceived utility based on user needs/requirements. The purpose of a website is clear when it 1) establishes a unique and visible brand/identity, 2) addresses visitors’ intended purpose and expectations for visiting the site, and 3) provides information about the organization and/or services. Simplicity is achieved by using 1) simple subject headings, 2) transparency of information (reduce search time), 3) website design optimized for computer screens, 4) uncluttered layout, 5) consistency in design throughout website, 6) ease of using (including first-time users), 7) minimize redundant features, and 8) easily understandable functions. Readability is optimized by content that is 1) easy to read, 2) well-written, 3) grammatically correct, 4) understandable, 5) presented in readable blocks, and 6) reading level appropriate.
The seven website design elements most often discussed in relation to user engagement in the reviewed studies were navigation (62.86%), graphical representation (60%), organization (42.86%), content utility (37.14%), purpose (31.43%), simplicity (31.43%), and readability (31.43%). These seven elements exceeded our threshold level of 30% representation in the literature and were included into a short list of website design elements to operationalize effective website design. For further analysis, we reviewed how studies defined and evaluated these seven elements. This may allow designers and researchers to determine and follow best practices for facilitating or predicting user engagement.
A remaining challenge is that the definitions of website design elements often overlap. For example, several studies evaluated organization by how well a website incorporates cognitive architecture, logical and hierarchical structure, systematic information arrangement and categorization, meaningful headings and labels, and keywords. However, these features are also crucial in navigation design. Also, the implications of using distinct logos and icons go beyond graphical representation. Logos and icons also establish unique brand/identity for the organization (purpose) and can serve as visual aids for navigation. Future studies are needed to develop distinct and objective measures to assess these elements and how they affect user engagement (Lee & Kozar, 2012).
Given the rapid increase in both mobile technology and social media use, it is surprising that no studies mentioned cross-platform compatibility and social media integration. In 2013, 34% of cellphone owners primarily use their cellphones to access the Internet, and this number continues to grow (“Mobile Technology Factsheet,” 2013). With the rise of different mobile devices, users are also diversifying their web browser use. Internet Explorer (IE) was once the leading web browser. However, in recent years, FireFox, Safari, and Chrome have gained significant traction (W3schools.com, 2015). Website designers and researchers must be mindful of different platforms and browsers to minimize the risk of losing users due to compatibility issues. In addition, roughly 74% of American Internet users use some form of social media (Duggan, Ellison, Lampe, Lenhart, & Smith, 2015), and social media has emerged as an effective platform for organizations to target and interact with users. Integrating social media into website design may increase user engagement by facilitating participation and interactivity.
There are several limitations to the current review. First, due to the large number of studies published in this area and due to this study being exploratory, we selected from the first 100 research publications on Google Scholar search results. Future studies may benefit from defining design to a specific topic, set of years, or other area to limit the number of search results. Second, we did not quantitatively evaluate the effectiveness of these website design elements. Additional research can help to better quantify these elements.
It should also be noted that different disciplines and industries have different objectives in designing websites and should thus prioritize different website design elements. For example, online businesses and marketers seek to design websites that optimize brand loyalty, purchase, and profit (Petre et al., 2006). Others, such as academic researchers or healthcare providers, are more likely to prioritize privacy/confidentiality, and content accuracy in building websites (Horvath, Ecklund, Hunt, Nelson, & Toomey, 2015). Ultimately, we advise website designers and researchers to consider the design elements delineated in this review, along with their unique needs, when developing user engagement strategies.
