A website with a few hundred pages can generate thousands of accessibility issues over the course of a year, simply because content, templates, and third-party scripts keep changing. And a one-time scan isn’t built to catch that drift. Monitoring is built to catch it, but vendors differ sharply in how they do it and what they report back.
That difference between catching drift and missing it comes down to a short list of decisions: how often a tool tests, how much of the site it can reach, and what shows up in the report afterward.
Below, we’ll cover what to look for in a monitoring tool, compare six tools side by side, and explain what a useful accessibility monitoring report should include.
What is Continuous Accessibility Monitoring?
Continuous accessibility monitoring is automated testing that rechecks a website for Web Content Accessibility Guidelines (WCAG) issues on an ongoing basis, so new issues surface as content changes instead of waiting for the next scheduled audit.
Websites change constantly. A team publishes a new page, updates a template, or adds a third-party script, and any of those changes can introduce a new accessibility issue. A one-time scan only captures the site as it looked on the day it ran. Continuous accessibility monitoring keeps testing after that scan, so new issues get caught close to when they appear, rather than at the next quarterly review.
What to Look for in an Accessibility Monitoring Tool
The most important features in an accessibility monitoring tool are testing frequency, coverage of dynamic and logged-in content, accuracy, reports that separate fixed from open issues, and a path to expert verification.
Use the six criteria below as a starting point for your vendor questionnaire or RFP. Each is phrased as a question you can put directly to a vendor.
Testing frequency: How often does the tool test, and what triggers a test? Ask whether the tool tests on every page load, daily, weekly, or only on demand. A site that publishes or updates content often needs testing that keeps pace with those changes.
Coverage: What content can the tool reach? Ask whether the tool reaches dynamic content, pages behind a login, PDFs, and mobile experiences. A crawler that only reads static pages will miss checkout flows and account dashboards, which are where many accessibility issues hide.
Accuracy: How does the vendor handle false positives? A tool that over-reports low-confidence issues wastes developer time chasing problems that aren’t real.
Reporting: Does the report separate fixed issues from open ones? A useful report maps each issue to the WCAG 2.X Level AA success criterion it violates, shows the affected pages, and tracks progress over time. It should also export cleanly for stakeholders outside your web team.
Fixes: Does the tool fix issues or only find them? Ask whether the tool fixes issues automatically or only lists them. A findings-only report still leaves the fix work to your developers.
Expert verification: Is there a path to human testing? Some WCAG criteria require human judgment and testing with assistive technology. Ask whether the vendor offers expert testing, and how those results flow into the same reporting.
Accessibility Monitoring Tools Compared
Accessibility monitoring tools differ in testing frequency, the content they can reach, and whether their reports show fixed issues or only findings.
Here’s a look at six accessibility monitoring tools and how they compare:
Each tool scans sites automatically; the real differences show up in how often they test, how much of the site they reach, and whether the report hands you a fix or just a finding.
The Best Website Accessibility Monitoring Tools
AudioEye
AudioEye Active Monitoring tests for new accessibility issues every time a visitor loads a page and fixes many of them automatically.
Because testing follows real user navigation, AudioEye’s monitoring concentrates on the pages your visitors use most. It refreshes with each page a visitor opens, rather than waiting for a scheduled crawl. The platform runs 400+ accessibility tests to identify potential WCAG violations and delivers more than 1.3 billion automated fixes to customers every day.
Issue reports list the pages affected, the WCAG success criteria involved, and the disability groups each issue affects so that teams can prioritize by real-world impact rather than raw count.
Siteimprove
Siteimprove(opens in a new tab) scans a full site and audits pages against WCAG. Its Dynamic Content Checker browser extension and a site-snapshot feature test content that a standard crawl can’t reach, including forms, booking flows, and cart pages.
Axe Monitor by Deque
Axe Monitor by Deque(opens in a new tab) continuously scans and reports on accessibility status against industry standards or custom guidelines. Results are prioritized so teams can fix what matters first, and issues can flow straight into Jira as tickets. Reports and analytics track progress over time. According to Deque's documentation, Axe Monitor runs on-demand or scheduled scans against WCAG, Section 508, EN 301 549, and Trusted Tester requirements.
Level Access
Level Access(opens in a new tab) runs automated scans during scheduled intervals, including on pages behind a login, and turns the results into progress reports. Its reporting dashboards track status across a portfolio of assets and combine automated and manual testing results.
Silktide
Silktide(opens in a new tab) renders pages in a real browser and tests multi-step user journeys through to checkout, highlighting the highest-impact issues first, per its own site. It integrates with CMS and development tools for continuous monitoring and retesting after fixes ship.
Acquia Web Governance
Acquia Web Governance(opens in a new tab) automatically scans a site for accessibility issues with improvement recommendations, scans for mobile accessibility issues, and lets teams assign issues to specific members. A History Center tracks compliance progress over time.

What Continuous Monitoring Cannot Do Alone
Automated monitoring alone cannot confirm WCAG 2.2 Level AA conformance, because some success criteria require human judgment and testing with assistive technology.
Monitoring is built for scale. It catches new issues across thousands of pages as fast as your content changes. But there’s a limit to what automated accessibility testing can catch: a scan can confirm that an image has alt text, not whether that text describes the image well. It can’t tell whether a custom menu actually works with a screen reader.
The strongest accessibility platforms layer monitoring with human testing. When you evaluate vendors, ask two questions:
Does the vendor offer expert testing with assistive technology?
How do the experts’ findings show up alongside monitoring results?
A vendor that can’t answer either leaves you managing two separate views of your site.
AudioEye is one example of this layered approach. Automated monitoring runs continuously; Expert Audits bring in specialists who test with screen readers and other assistive technology. Together, they keep your picture of accessibility up to date between audits, so a new issue on a high-traffic page gets caught when it ships, rather than months later at the next review.
What Should an Accessibility Monitoring Report Include?
A monthly accessibility compliance report should show issues found, issues fixed, open issues mapped to WCAG success criteria, the pages affected, and progress over time.
A complete accessibility reporting package should include:
Issues found and fixed: a running count of both, not just what’s currently open.
Open issues mapped to WCAG success criteria: this helps a developer know exactly which requirements and issues are violated.
Pages affected: the specific URLs or templates carrying each issue.
Disability impact: which disability groups an issue affects so that teams can prioritize by real-world consequence.
Severity or priority: a way to triage high-impact issues ahead of minor ones.
Progress over time: a dated history showing the trend, not a single snapshot.
Exportable format: something a compliance manager can hand to procurement or legal without retrofitting it first.
These reports work best as documentation of ongoing effort. A documented history of issues found and resolved shows that a team is actively managing accessibility, which matters to procurement and legal reviewers. A report is evidence of process, not a guarantee of legal compliance, so pair it with expert audit results when the stakes are high.
Choose Monitoring that Keeps Pace with Your Site
The right accessibility monitoring tool tests as often as your content changes, reaches the pages that matter most, and reports what’s been fixed as well as what’s been found. Pair it with expert verification, and you have a program that holds up to procurement, legal, and your users.
AudioEye brings those pieces together in one platform. Active Monitoring tests for accessibility issues every time a visitor loads the page and fixes common issues automatically, delivering more than 1.3 billion automated fixes every day. Expert Reporting shows fixed and open issues side by side, each mapped to the WCAG criteria it violates and the disabilities it impacts. Expert Audits add human testing where automation reaches its limits. The result is continuous accessibility monitoring that identifies issues, fixes them, and documents your progress between audits, so your accessibility program keeps pace with your site rather than falling behind.
