Why Accessibility Matters in St. Louis
Enterprises across the Gateway City operate in heavily regulated sectors from health networks to corporate headquarters where inclusive design is mandatory. As legal scrutiny intensifies nationwide, local brands must ensure digital touchpoints accommodate users of all abilities without sacrificing design aesthetic or speed.
Federal filings tracked by Seyfarth Shaw highlight growing legal exposure for unoptimised digital interfaces across corporate sectors.
The vast majority of online properties fail basic automated screening, exposing regional businesses to preventable compliance risks.
Visual contrast issues dominate audit logs, requiring precise code remediation to ensure total clarity for all online visitors.
our approach
How We Deliver ADA Conformance
Our approach combines automated diagnostics with comprehensive manual testing using screen readers and keyboard navigation. We resolve underlying code defects to guarantee durable, long-term compliance.
Technical Audit
We conduct exhaustive evaluations covering WCAG 2.2 Level AA criteria. By combining automated crawlers with assistive technology testing, our engineers identify contrast defects, missing ARIA tags, and structural keyboard barriers across every digital template, establishing a clear roadmap for total remediation.
Code Remediation
Rather than relying on brittle overlay widgets, we directly refactor your source code. Our developers update HTML semantics, correct focus states, build accessible form controls, and embed dynamic screen reader announcements that function seamlessly across all modern browsers.
Assisted User Testing
We validate remediation workflows through hands-on testing with native screen readers such as NVDA, JAWS, and VoiceOver. This process ensures complex interactive components, modal dialogues, and transactional checkout funnels operate intuitively for users navigating without standard pointers.
Continuous Monitoring
Compliance is an ongoing discipline as content evolves. We deploy automated monitoring pipelines and quarterly manual audits to catch regressions, verify continuous conformance, and furnish formal VPAT documentation to safeguard your organisation against compliance issues and emerging litigation risk.

Inside the work
How We Deliver ADA Conformance

Services

Pairing accessibility with paid search and performance campaigns drives superior return on advertising spend across competitive markets. Compliant landing pages reduce bounce rates and deliver higher Quality Scores across Google Ads, ensuring regional marketing budgets convert targeted traffic from all user demographics without digital friction or wasted media investment.
Accessible design elevates brand perception by enforcing visual hierarchy, optimal typography, and elegant colour contrast. Integrating WCAG benchmarks into your core design systems ensures creative assets remain distinctive, modern, and aesthetically compelling while guaranteeing inclusive readability across all customer touchpoints throughout the broader regional commercial marketplace.
Analytics platforms must accurately track assistive technology users to identify drop-off patterns and conversion bottlenecks. We configure custom event tracking that captures screen reader interactions and keyboard navigational milestones, granting your marketing team rich behavioural insights without compromising user privacy, regulatory compliance standards, or baseline page performance.
Our engineering team integrates compliance directly into modern CMS architectures such as WordPress, Shopify, and custom React platforms. We build accessible component libraries and automated CI/CD validation checks, enabling your internal marketing team to publish fresh content and campaign assets without risking compliance drift or structural regression.
