Hidde de Vries’ short and to-the-point article between analytics and accessibility contains three important highlights:
- It is impossible to reliably measure “disability” through web analytics
- Even if it were, those numbers would rather be a measure for the quality of a site (e.g. being avoided by users with certain disabilities) than its potential reach
- Health-related variables should never be a metric for privacy reasons
But the most important one is at the end:
Accessibility features on our site won’t benefit everyone all the time, that would be an exaggeration, but they often benefit many more people than just specific groups of people with disabilities.
So stop obsessing over inaccurate numbers and simply think “inclusive” at all times. Problem solved, no user tracking necessary.
