What I learned in my summer internship researching digital content accessibility
In this post, User Experience team intern Hannah Watson shares her work over the summer researching digital content accessibility with the EdWeb 2 publishing community.
Introduction
As part of my internship with the User Experience Service, I have been investigating digital accessibility at the content level across University web pages, particularly on EdWeb 2 sites. Digital accessibility at the content level is about applying principles of accessibility to how web content is written and formatted. This includes, but is not limited to, content features such as heading levels, links, and alt text. It does not include anything that is not involved with content design or that is controlled at a higher level by the Content Management System (CMS), such as font, font size, or colour contrast.
Research aims and scope
The specific research questions for this project were:
- How do web publishers learn about digital content accessibility?
- What do web publishers know about digital content accessibility?
- How do web publishers implement digital accessibility requirements and principles in their content?
- What challenges do web publishers face in creating digitally accessible content?
More comprehensively, I was investigating the accessibility of:
- Heading levels
- Ensuring that heading levels are used correctly
- Not using heading levels for emphasis
- Links
- Clear and concise link text which describes the linked destination
- Link text which makes sense on its own
- Avoiding URLs on web pages
- Lists
- Alt text
- Clear link text that describes the image
- Images
- Ensuring that all images have appropriate alt text
- Avoiding images of text
- Videos
- Including human-corrected captions with any videos uploaded to web pages
- Making sure that transcripts are available for all videos uploaded to web pages
- Italic, bold, and underlined text

This research has been necessary for the User Experience team as it allows us to identify which areas of content accessibility are challenging for web publishers. From this, the team can adapt guidance and training to provide extra support on these more challenging areas where possible.
Research methods
Interviews with web publishers
I started my research by setting up short, informal interviews with six University web publishers. In these interviews, I asked the publishers about their experiences of creating digitally accessible content. The aim of these conversations was to understand how publishers learned about digital accessibility and what challenges they face when making content as accessible as it can be. During the interviews, we referred to web pages that these publishers work on to get concrete examples that illustrate the topics we discussed. Through these interviews, I was able to identify a number of trends, particularly in the challenges that the interviewees and their colleagues face.
Survey of EdWeb 2 publishers and the Web Accessibility Special Interest Group
Following these interviews, I created a survey to further investigate the findings and collate more supporting evidence for these findings. The survey consisted of 10 questions, three of which were demographic based as a filter, with a final question asking permission to follow up with those who responded.
The other six questions asked about:
- which actions the participants took to make their content digitally accessible
- what resources they used to do so
- what challenges they face in doing so
The findings from the survey were effective in making the information gathered in interviews more robust and provided further evidence for some trends that were identified previously.
To publicise this survey, I sent a brief statement explaining my research into two Teams channels, the Web Accessibility Special Interest Group and the EdWeb 2 Community. Overall, the survey received five responses, and while this is a limited number, I found that it helped to support the findings from the interviews.
Analysis of Effective Digital Content workbooks
The final method of research that I used to learn about the digital accessibility of content on University web pages was by looking at pages that were submitted within Effective Digital Content workbooks as part of the course. The course requires learners to choose pages from a University website and assess the effectiveness of the content. By looking at the pages that learners selected, I was able to use active examples and make note of content accessibility issues that were present on live pages. This process also highlighted a number of trends.
This method of research was also useful in that it provided two separate sources of data. Firstly, the answers in the workbook helped me to gauge learners’ understanding of the principles covered in the course. Secondly, the web pages linked by those taking the course allowed me to have live examples of content to assess against content accessibility principles. While there was not necessarily overlap between the answers in the workbook and the pages submitted as part of the workbook (as some people may not have been fully or at all responsible for the content on those pages, or the content could have been updated since the workbook was submitted), it was useful to see these things separately.
Findings about accessibility
Combining findings from all areas of research for this project, I have identified a number of trends in the accessibility of digital content.
Headings, alt text, and links are the principles most often put into practice by participants
In the interviews and the survey, participants were asked what principles of accessible digital content they actively used when designing content. More than half of participants mentioned three principles in particular, with all participants mentioning at least two, which were:
- using the correct heading levels
- adding meaningful alt text to an image
- writing clear and descriptive link text
Interestingly, while these principles were mentioned frequently by participants, and evidenced by the websites that we discussed in interviews, they are also principles that are often missed on University web pages. This is discussed in more detail in the corresponding sections further on in this post.
PDFs are hard to avoid
One standout finding from the interviews was that web publishers sometimes struggle to find an effective alternative to PDFs. While PDFs are not necessarily accessible, they do have benefits which make them useful for publishers. For example, they are downloadable, searchable, and cannot be easily edited without permission from the owner. There are ways to make PDFs more accessible, such as avoiding decorative images, adhering to accessible content design principles within the PDF, and checking colour contrast. However, the interviewees were more in favour of finding a way to turn their content into a webpage as this is more likely to result in accessible content.
Out of the survey responses, three also mentioned that they had recently chosen to publish content as a web page rather than as a PDF, highlighting their knowledge that a web page is preferable in terms of accessibility. However, their personal preferences or how difficult they found this is unknown as I was unable to follow up with these participants.
Heading levels are often skipped and headings vague
Across web pages that I assessed for correct heading levels, there were several which skipped heading levels throughout the page content, such as going straight to a heading 3 without that heading being nested within a heading 2 section. Additionally, headings on the University web pages that I investigated were often generic, instead of being specific about what a page or section will contain, which is the recommended approach.
The fact that the web publishers who were interviewed and surveyed were aware of the importance of correct headings levels and specific headings, and that the majority of these publishers have attended a staff training or used the editorial style guide, suggests that the guidance provided is accurate and useful for publishers.
To increase the use of correct heading levels, as well as clear and descriptive headings on web pages, participant responses suggest that increasing the reach and engagement of existing training and resources involving headings would be effective. This includes training provided by the User Experience Service, such as Effective Digital Content or Content Improvement Club, and the University of Edinburgh editorial style guide.
Alt text is well written but sometimes missed
In three of the interviews, and in two survey responses, participants mentioned that they struggled to find the time to add alt text to images on their web pages. However, participants in the interviews also stated that they understood the importance of alt text, and what writing meaningful and clear alt text involves. This is reflected in the answers in Effective Digital Content workbooks. The course contains a question asking learners to write meaningful alt text for two images, and this question is often answered well. This suggests that web publishers understand how to write alt text, and that the obstacle in doing so is more likely to be related to time and resource.
One way that time constraints on adding alt text could be improved is to reduce the number of images on a web page, which will not only make this task more manageable but also is also more sustainable.
Explaining acronyms and abbreviations is common
All five responses to the survey stated that they had explained an acronym or abbreviation recently. Although this did not come up in the interviews often – only once – the survey responses suggest that this is common practice for web publishers who are familiar with digital accessibility principles.
Link text is frequently inline or not descriptive
Participants stated that they understand the importance of clear link text as a principle and make effort to implement this into their content. However, similar to headings, this sentiment is not reflected across numerous University web pages. In some of the pages submitted as part of the Effective Digital Content workbooks that I investigated, there were frequent occurrences of inline link text, or link text that does not clearly describe the linked destination.
To increase the writing of link text on a separate line, as well as clear and descriptive link text, participant responses suggest that increasing the reach and engagement of existing training and resources involving links would be effective. This includes training provided by the User Experience Service, such as Effective Digital Content or Content Improvement Club, and the University of Edinburgh editorial style guide.
Findings about staff experience and engagement
A trend from both the interviews and survey responses is that for many of the people involved with this research, their knowledge of digital accessibility started with a personal interest. Specific examples of this that participants mentioned include learning about accessibility as a student (and then going on to be an accessibility advocate for a student society) and working with disabled students and learning through experience.
During the interviews, multiple staff members mentioned that they believe, through their experiences, that a large part of issues with creating accessible digital content at the University surrounds communication. A combination of factors was discussed that had communication at the centre, including:
- the importance of digital accessibility not being widespread enough.
- consistency about expectations between schools or areas of the University, such as one page being edited by multiple schools or areas and having different standards.
Job-based constraints were also mentioned frequently, such as limited time to add alt text to all images on a web page and working on a page where the lead publisher takes a design forward approach which can sometimes clash with accessible content principles. These answers were also reflected in the survey responses, with all of the responses mentioning either one or both of these problems.
What resources do web publishers use for learning about and developing their digital accessibility skills?
The primary resource that participants mentioned using to learn about digital accessibility and develop their skills was University-provided staff training, with 10 of 11 participants mentioning this. Effective Digital Content was specifically mentioned twice, and Content Improvement Club three times. In the interviews, two participants mentioned more general staff training, with one survey response saying the same. In the survey responses, three participants also said that they used training provided by the Disability Information Team.
The Web Content Accessibility Guidelines 2.2 (WCAG) is another resource that was frequently mentioned by participants, with six in total saying that this is a resource that they use as guidance on accessibility.
The University of Edinburgh editorial style guide was mentioned by five participants as a resource that they used to provide guidance on digital accessibility, in which the guidance reflects what publishers learn in training courses, meaning that information they take from the style guide is in line with accessibility and content design training.
What I learned from researching content accessibility approaches in EdWeb
I learned a lot during my time researching how web publishers at the University of Edinburgh approach creating accessible digital content. I thoroughly enjoyed the opportunity to work with staff from a variety of different areas of the University. This helped me to learn how to identify commonalities in interview and survey responses despite the areas of work being distinct. I also enjoyed this because I was able to learn much more about the work that goes on across the University and what the work of other teams involved.
I also particularly enjoyed the format of my internship being a combination of individual work and working with other members of my team and the Disability Information team. This balance allowed me to set my own goals while still getting the opportunity to work and learn collaboratively as part of a team, prioritising my tasks between my own and those that I was working on with others.
A limitation of my work was that it was much easier to contact and work with staff who have a genuine interest in the subject area of accessibility, which does not lead to research that is representative of how University staff approach digital accessibility as a whole. Having done the research that I have so far, a continuation of the research would be most beneficial if it focused on the experiences and approaches of staff who are less familiar with digital accessibility requirements and principles, as this would create a more well-rounded understanding of web publisher accessibility approaches at the content level.
Furthermore, another limitation of the work was the time constraints which have restricted my ability to develop solutions to issues identified during the research period. This was expected to a degree, as the solutions depended on the outcomes of the research, which has taken the majority of the 12-week period. The positive outcome of this is that the research and findings will provide the User Experience service with information that allows for both further research and for adaptations to guidance and training if it is deemed necessary.
Conclusion
This research has helped the User Experience Service to assess their training and the resources that are available for publishers to learn more about digital content accessibility. Keeping in touch with the publishing community through projects like this helps the team to direct their effort to real challenges that publishers face on a day to day basis.
The research completed throughout the duration of this project will be supported and advanced by further investigation, particularly by communicating with web publishers who are less involved with digital accessibility as a whole. This will likely help in providing more concrete solutions to digital content accessibility issues across EdWeb 2 pages.
