“Not verified” means the recorded evidence does not settle this specific check. It does not mean the feature is absent. Read the scoring method.
Focus on up to three products →ASK BETTER QUESTIONS
Before you buy website accessibility monitoring software.
What to look for
- Pilot on a real form, an authenticated journey and a representative PDF.
- Include disabled users and manual specialist testing in the evaluation.
- Buy a remediation process with accountable owners, not a compliance badge.
What changes the cost
- Domains, page and PDF allowances and scanning frequency.
- Manual audits, assistive-technology testing and staff training.
- CMS integrations, developer tooling and AI usage limits.
What to watch out for
- Treating a scanner score as a percentage of legal compliance.
- Using an overlay as a substitute for fixing source content.
- Closing issues without rechecking the affected user journey.
Common questions
Can an automated tool prove our website is accessible?
No. Some checks require human judgement, and automated results can be incomplete or misleading.
Is the public-sector rule identical for every private business?
No. The public-sector regulations have a defined scope. Assess the duties and procurement requirements relevant to your organisation.
Should AI publish accessibility fixes automatically?
Require review and regression checks. A plausible change can alter meaning, keyboard behaviour or assistive-technology output.
