I am struggling with this right now. Alt text, captions, audio (read to me) options are good. I work with an accounting software app that redesigned its palette to red, black, and gray. No green to signify income. Made no sense to me and their gray text (also very skinny sans serif) made reading many nav bars difficult. Some URLs are accessible from the build-out, but the DIY sites often don't have the same capacity. As with secure sites, I think google will be downgrading those sites with little or no compliance or accessibility add-ons.
The large number of people who have disabilities, coupled with the challenges that they face, is one of the reasons that the Americans with Disabilities Act (ADA) was passed in 1990.² As its name suggests, the ADA is designed to protect individuals with disabilities in the United States. The ADA essentially makes it illegal for any government entity or business to provide goods and services to the general public without ensuring that the entities are accessible by people with disabilities. In today’s digitally driven world, many businesses fail to follow web accessibility best practices. In fact, this is why the Supplemental Advanced Notice of Proposed Rulemaking (SANPRM) was created by the U.S. Department of Justice (DOJ). To ensure that they are implementing digital accessibility best practices, organizations are encouraged to use the WCAG 2.1 technical requirements.³
The words in the tag should be more than a description. They should provide a text equivalent of the image. In other words, the tag should include the same meaningful information that other users obtain by looking at the image. In the example of the mayor’s picture, adding an “alt” tag with the words “Photograph of Mayor Jane Smith” provides a meaningful description.
