> ARIA markup on HTML only benefits those using assistive technology. This specific case: ARIA labels also help search engine indexers find pages and extract information within pages more effectively. Excluding contemporary concerns about search engines intercepting advertising revenue by doing this, it is undoubtedly better for the able-sighted and blind user alike to have the option of finding an answer by visiting one page rather than two. More philosophically: if accessibility makes things easier for people with a disability, that means it is easier for someone emulating a disability. For instance, whenever I'm holding something in one hand, I'm effectively emulating the abilities of a physically one-handed person, so if you make a design that works for one-handed people, you're also giving everyone else the extra opportunity to multitask. > I'm not saying accessibility isn't important, but these kinds of arguments that it is always cheap and easy often actually make it harder for engineers to get the resources they need to implement it successfully. Parent poster wasn't saying it is cheap and neither would I, but whilst the incidental benefit of accessibility improvements to able-bodied people might not seem obvious, it always exists.
