Human accessibility (readability) helps "findability" because search engine crawlers are designed to prioritise human-readable pages. But also, "web accessibility" emphasises users with a range of abilities being able to access the data (information) using a variety of assistive technologies.
When publishing data on the web, take account of web accessibility guidelines. It is currently challenging to make web visualisations of geospatial data accessible to assistive technology. “Maps on the Web” is looking at this?
(side note: I take it "Maps on the Web" is referring to @maps4html?)
Some comments and documents mention human accessibility, such as:

I'd just like to note that - for their 2020 W3C-OGC Joint Workshop Series on Maps for the Web presentation - Nicolò Carpignoli (W3C APA Invited Expert) & Joshue O Connor (W3C WAI) compiled a set of User needs and Requirements: [PDF] Towards Accessible Annotations for a Native Map Viewer for the Web Platform, which I'd like to think is a useful reference to incorporate (somewhere).
