Benefits
- Accessibility
Supporting non-visual browsing methods means people can access your content more easily when using specialized accessibility aids. - Conversion
Increasing compatibility by supporting a wider range of devices, beyond the most popular or well-known hardware and software, will enable interactions with new audiences and increase the likelihood of a positive outcome. - Environment
Allowing non-visual browsers to interact with your content can help to reduce overall emissions. Non-visual browsers may lack a display, which reduces the environmental impact of browsing.
