Accessibility monitoring includes scheduled automated scans, recurring issue tracking, alerts for new accessibility issues, and reporting over time. Costs for monitoring services typically range from a few hundred dollars per year for basic scan scheduling to several thousand dollars annually when bundled with a conformance management platform.
| Key Point | What It Means |
|---|---|
| Core Function | Running automated scans on a recurring schedule to detect new accessibility issues over time |
| Common Frequencies | Daily, weekly, monthly, or custom intervals depending on the service |
| Scan Coverage | Automated scans identify approximately 25% of accessibility issues; monitoring does not replace audits |
| Typical Cost Range | A few hundred dollars per year for standalone monitoring, up to several thousand when part of a broader platform |
What Features Are Included in Accessibility Monitoring?
Monitoring is the practice of running automated scans on a set schedule. The scans load each page, evaluate HTML, CSS, and ARIA attributes, and check them against Web Content Accessibility Guidelines (WCAG) success criteria.
Most monitoring services include scan scheduling at daily, weekly, or monthly intervals. After each scan cycle, the service generates a report that tracks which issues are new, which persist from previous scans, and which have been remediated.
Some services also include authenticated page scanning, which uses a browser extension running within an active session to reach pages behind a login. Alerting is another common feature, notifying teams by email or dashboard notification when new issues appear or when issue counts change significantly.
What Monitoring Does Not Cover
Because monitoring relies on automated scans, it identifies approximately 25% of WCAG issues. The remaining 75% requires human evaluation, including screen reader testing, keyboard testing, and visual inspection.
Monitoring tracks the issues that scans can detect. It is not a substitute for a manual accessibility audit or broader monitoring strategy. Organizations that rely solely on scan-based monitoring will miss the majority of accessibility issues on their sites.
How Accessibility Monitoring Features Affect Cost
Pricing for monitoring depends on several factors. The number of pages scanned is the most direct cost driver. A 50-page site costs less to monitor than a 500-page site.
Scan frequency also affects price. Daily scans cost more than monthly scans because they consume more processing resources. Authenticated scanning, which covers logged-in pages, often adds to the cost as well.
Standalone monitoring services that offer only scheduled scans and basic reporting sit at the lower end, often a few hundred dollars per year. When monitoring is bundled into a conformance management platform with issue tracking dashboards, prioritization by user impact and risk factor, and remediation workflows, annual costs rise into the low thousands.
Where Monitoring Fits in an Accessibility Budget
Monitoring is a recurring expense, unlike an audit, which is a periodic project cost. Most accessibility audits start at 1,000 dollars and range to 3,000 dollars as a one-time engagement. Monitoring fills the space between audits by catching regressions and new issues introduced through content updates or code changes.
Organizations that pair regular monitoring with periodic audits get both continuous automated coverage and the thorough human evaluation needed for full WCAG conformance. The combined annual cost depends on site size, scan frequency, and audit scope, but monitoring itself is typically the smaller line item.
The value of monitoring is in what it catches early. Identifying a regression the week it appears costs far less to remediate than discovering dozens of accumulated issues months later during an audit cycle.
