I scanned 10 UK web agency websites for WCAG 2.2 violations — here's what I found

I'm 15, and I recently built an accessibility scanner that checks websites against WCAG 2.2 standards. To stress-test it, I decided to scan the websites of 10 UK web development agencies — the companies that build websites for a living. The setup I ran a single-page scan (homepage only) on each agency's site using axe-core, checking against 90+ WCAG 2.2 rules. No full crawls — just the home page. The results were as follows: Agency A: 8 violations (2 critical, 5 serious) Agency B: 8 violations (2 critical, 3 serious) Agency C: 8 violations (1 critical, 2 serious) Agency D: 7 violations (2 critical, 2 serious) Agency E: 5 violations (2 critical, 2 serious) Agency F: 5 violations (0 critical, 1 serious) Agency G: 4 violations (0 critical, 1 serious) Agency H: 4 violations (0 critical, 1 serious) Agency I: 2 violations (0 critical, 1 serious) Agency J: 0 violations — clean pass 9 out of 10 failed. Only one agency had a completely clean homepage. Totals across all 10 sites: 51 violations 9
