Search engine optimization and accessibility often overlap. Accessibility of websites should be an important concern for those working with and within the web space. Cognitive, visual and physical challenges need to be addressed in order for the website to be fully accessible, which is also a legal requirement in many instances. Accessibility is guided by four principles – the content needs to be operable, perceivable, robust and understandable. Additionally, accessibility through different platforms and periodic updates also needs to be ensured.
- Accessibility applies to users with physical impairments, but also environmental and situational impairments.
- Site maps help users to navigate the site, but also are used by search engine crawlers.
- Alt text for images benefits the visually impaired and is incorporated into SEO.
“In addition to being imperative to user experience, an accessible website is also required by law in most cases.”
