Accessibility regression monitoring for web agencies

How agencies can monitor automated accessibility regressions after site changes without presenting scan results as legal or WCAG certification.

Best fit

UK/EU web, Shopify and digital agencies managing multiple client sites.

What the focused offer actually does

Catch new automated accessibility regressions after site changes without rerunning scans manually.

Current commercial scope: from US$500

Practical workflow

Four checks before you add more software.

The useful unit is a bounded operating workflow: explicit input, evidence, human judgement where needed, and a visible handoff.

Start with important public URLs and a stable baseline rather than scanning every page with no ownership model.

Alert on meaningful NEW/PERSISTING/FIXED state changes so teams can distinguish regressions from known debt.

Preserve enough evidence to reproduce the automated finding after a deployment.

Escalate consequential findings to manual review; automated monitoring is not a conformance certification.

Evaluating Web Accessibility Overview

W3C WAI

W3C explains that evaluation tools help but no tool alone can determine accessibility; knowledgeable human evaluation is required.

Understanding Conformance — WCAG 2.2

W3C WAI

W3C describes conformance testing as a combination of automated testing and human evaluation.

Boundary

Automated evidence requires manual review

No claim of WCAG conformance, legal certification or full accessibility audit

No accessibility overlay or auto-remediation promise
