A form-letter ADA accessibility claim can cost your client five figures before anyone checks if it's even valid. Here's the AI audit that catches the real violations before a serial-plaintiff firm's scanner does.

The problem
A handful of law firms run automated scanners against small-business websites looking for WCAG violations — missing alt text, low-contrast buttons, unlabeled form fields, no keyboard navigation — then mail a demand letter citing the ADA and offering to settle quietly for a few thousand dollars before anyone involved has to prove the site actually locked out a real person. Most agencies never put accessibility on the build checklist or the QA pass, because nothing about it showed up broken in a browser. The client finds out when the letter arrives, and the first call is to the agency that built or maintains the site, asking some version of 'how did we miss this.' There usually isn't a good answer, because nobody ever checked.
The fix
Run a recurring AI-assisted WCAG audit across every live client site — not just new builds — triage the output by how likely a scanner bot is to flag it first, fix that layer before it becomes a letter, and keep a dated remediation log that does the actual defending if one shows up anyway.
The Playbook
Scan every live client site, not just the ones launching this quarter
Run axe, WAVE, or Lighthouse's accessibility pass against every active client site, including ones that shipped clean a year ago. Sites drift: a blog post goes up without alt text, a marketing team embeds a third-party widget that breaks keyboard navigation, a redesign swaps a button color that quietly fails contrast. The scanners the plaintiff firms use run against the live site today, not the version that passed review at launch.
Feed the raw scan output through Claude to triage by exposure, not just issue count
A raw accessibility scan returns dozens of flagged issues with no sense of which ones actually matter. Most are minor. A few are exactly what a cheap automated scanner is built to catch first.

[PASTE SCAN RESULTS]
For each flagged issue:
1. Map it to the specific WCAG 2.1 AA success criterion it violates
2. Rate how likely a basic automated scanner (the kind used to generate mass ADA demand letters) would flag this as an obvious violation — high/medium/low
3. Rate actual impact on a real user relying on a screen reader or keyboard navigation — high/medium/low
4. Estimate fix complexity — quick fix, moderate, or requires a rebuild of that component
Sort the output so anything rated "high" on both scanner-likelihood and user impact is at the top. Flag anything that's a quick fix with high scanner-likelihood separately — that's the first pass.Fix the scanner bait first: alt text, contrast, form labels, skip links
Missing alt text, insufficient color contrast, unlabeled form inputs, and missing skip-navigation links are the four issues almost every automated accessibility scanner catches instantly, and they're also usually the fastest to fix. Clearing this layer across every active client site removes most of what makes a site an easy, low-effort target before touching anything structurally harder.
Keep a dated remediation log — this is the artifact that actually matters
Many ADA demand letters get settled for a few thousand dollars regardless of merit, because fighting one properly costs more than paying it. A dated log showing the agency ran a scan, fixed what it found, and re-scans on a schedule is the single strongest thing a client's attorney has to push back on a letter or negotiate it down — it demonstrates ongoing good-faith effort instead of total neglect. Store the scan date, issues found, issues fixed, and the re-scan date for every site, every quarter.
Write a short, factual accessibility remediation summary for a client file, based on this scan and fix data.
Scan date: [DATE]
Issues found: [PASTE TRIAGED LIST]
Issues fixed and dates: [LIST]
Issues deferred and why: [LIST]
Next scheduled scan: [DATE]
Keep it factual and dated, written as a record an attorney could read, not as a marketing summary.Make it a standing quarterly line, not a one-time cleanup
New content, new plugins, and new third-party embeds reintroduce violations constantly, so a one-time fix decays within a quarter. Bundle the recurring scan into the maintenance retainer as a named line item instead of absorbing it as an unbilled favor — it's real, recurring work that protects the client from a real, recurring risk.
What changes
Fewer 'how did we miss this' calls when a demand letter lands, a dated remediation record that actually helps if one shows up anyway, and a new defensible line item on the maintenance retainer instead of an unbilled scramble after the fact.
A client calls, reads out a letter, and asks how the agency missed this. The letter cites the ADA, lists a handful of accessibility violations on their website, and offers to settle quietly for a few thousand dollars before anyone has to prove a real person was ever actually locked out. The agency built the site. Nobody on the team has ever run an accessibility scan against it.
That conversation is becoming routine for small-business web and digital agencies, and it's almost never triggered by a person. A handful of law firms run automated scanners against thousands of small-business sites, flag the same handful of WCAG issues every time — missing alt text, low-contrast buttons, unlabeled form fields, no keyboard navigation — and mail a formulaic letter. Whether the underlying legal claim would hold up in court rarely matters, because settling for a few thousand dollars is almost always cheaper than finding out.
Why this never made it onto the build checklist
Accessibility violations don't show up broken in a browser. The site looks fine, the client approves it, the project closes. Nothing about a missing alt attribute or a 4.3:1 contrast ratio fails a normal QA pass, because normal QA was never built to check for it. It's invisible right up until a scanner built specifically to find it does.
The fix isn't a one-time fix
Running a scan once at launch catches the version of the site that existed on launch day. Six months later a blog post goes up without alt text, a marketing team embeds a review widget that breaks keyboard navigation, a redesign swaps a button color and nobody checks contrast. The site drifts out of compliance quietly, the same way it drifted in the first time, and the scanner that finds it runs against the live site today — not the clean version from the handoff deck.
The agencies protecting clients from this treat it as a recurring scan, not a launch-day checkbox: run axe, WAVE, or Lighthouse against every active site quarterly, triage the output by how likely a cheap automated scanner is to flag it first, and fix that layer before anyone else finds it.
The log is the real defense
Most of these letters settle regardless of merit, because the cost of defending one properly outweighs the settlement. What actually changes the negotiation is a dated record: a scan ran on this date, these issues got fixed, here's the next scheduled scan. That single artifact is the difference between "the client never checked" and "the client has an ongoing, documented, good-faith accessibility program" — and it's the kind of thing a client's attorney can actually use.
Bottom line
This isn't a hypothetical risk agencies can keep deprioritizing. It's a recurring, automatable threat aimed at exactly the kind of small-business websites most agencies build and maintain, and the fix costs a fraction of what one settlement does. A quarterly scan, a triage pass, and a dated log turn an unbilled crisis call into a standing line on the maintenance retainer — and the client never finds out the hard way that nobody was checking.
