Comparison
Accessibility compliance approaches compared
Overlay, automated scan, manual audit, source-level fixes, continuous monitoring: strengths, limits and when each makes sense.
There are several ways to move toward accessibility compliance. None is magic, and the best strategy often combines approaches. An honest overview.
Five approaches, in plain terms
- Automatic overlay: a widget that layers on top at load time, without touching the source code.
- Automated scan only: an engine detects measurable issues, with no fix or follow-up.
- One-off manual audit: an expert checks the criteria, including non-automatable ones, at a point in time.
- Audit plus source-level fixes: you measure, then truly fix in the code.
- Continuous monitoring: you re-check regularly to catch regressions.
Comparison
| Approach | Real compliance | Durability | For whom |
|---|---|---|---|
| Automatic overlay | Low | Fragile | Avoid for compliance |
| Automated scan only | Partial | One-off | Quick baseline |
| One-off manual audit | High at that moment | Expires | Expert validation |
| Audit plus source fixes | High | Good | Real compliance |
| Continuous monitoring | Maintained | Strong | Sites that evolve |
The balanced approach
In practice, the winning combination is: an automated scan for a quick baseline, source-level fixes to solve the real problems, a human check for non-automatable criteria, and continuous monitoring to avoid regressions. It is this cycle logic, rather than a single solution, that makes compliance achievable and durable.

Frequently asked questions
Should I pick a single approach?
No. The approaches complement each other: scan to measure, fix to solve, human check to complete, monitoring to last.
Is a one-off audit enough?
It gives a snapshot at a point in time. As a site evolves, continuous monitoring is needed to stay compliant.
