Three lenses, one standard

When we talk about web accessibility, we are talking about whether people with disabilities: visual, auditory, motor, cognitive, or neurological: can perceive, navigate, understand, and interact with your website. That includes someone using a screen reader, navigating by keyboard only, relying on captions, or needing high contrast and readable typography.

For too long, accessibility was treated as a post-launch checkbox: add alt text, run a quick scan, call it done. That approach fails users, exposes organizations to legal risk, and leaves SEO value on the table. Here is how the three lenses: user experience, legislation, and search: fit together.

// Legislation

The legal landscape

Accessibility law varies by country and region, but the direction is consistent: digital products are expected to be usable by people with disabilities. The technical benchmark most courts and regulators reference is WCAG 2.1 Level AA (with WCAG 2.2 now the current W3C recommendation).

United States: ADA The Americans with Disabilities Act does not explicitly name websites, but courts have repeatedly ruled that inaccessible sites violate Title III. Thousands of demand letters and lawsuits target ecommerce, hospitality, healthcare, and financial services sites each year.
United States: Section 508 Federal agencies and contractors must meet Section 508 standards, which align with WCAG 2.0 Level AA. If you sell to government, this is non-negotiable.
Canada: ACA & provincial law The Accessible Canada Act (2019) applies to federally regulated sectors. In Ontario, the AODA requires WCAG 2.0 Level AA for public-sector and large private-sector websites. British Columbia and other provinces are moving in the same direction.
European Union: EAA The European Accessibility Act (enforceable from June 2025) requires ecommerce, banking, transport, and other digital services to meet WCAG-based accessibility requirements across member states.

Practical takeaway: WCAG 2.1/2.2 Level AA is the de facto global standard. Building to that level from the start is cheaper than retrofitting after a complaint: or after a competitor outranks you on experience and technical quality.

// Process

A process that actually works

Accessibility is not a one-time audit. It is a discipline woven into discovery, design, development, and QA: the same way performance and security are.

// SEO

Why Google cares too

Search engines do not have a separate “accessibility score” that directly ranks pages. But many accessibility practices overlap with core SEO fundamentals: and Google has been explicit that helpful, people-first content is what they reward.

Semantic HTML = crawlable structure

Proper heading hierarchy (<h1> through <h6>), landmark regions (<nav>, <main>, <article>), and lists give screen readers and search crawlers a clear map of your content. Div soup with no semantics helps neither.

Alt text serves two audiences

Descriptive alt attributes on meaningful images help visually impaired users understand content. They also give search engines context for image search and page relevance. Keyword-stuffing alt text fails both audiences: write for humans first.

Page experience signals

Accessibility improvements often improve Core Web Vitals and mobile usability: readable font sizes, sufficient contrast, tap-friendly buttons, and reduced motion options. Lower bounce rates and longer session duration: both influenced by usability: are behavioural signals that support rankings.

Structured data and rich results

FAQ, HowTo, and Article schema markup must reflect content that is actually visible on the page. Accessible, well-structured content makes valid schema easier to implement: and invalid or hidden schema can trigger manual actions.

Video and media

Captions and transcripts are accessibility requirements for pre-recorded video under WCAG. They also create indexable text, improve watch time, and expand reach to sound-off mobile users: a direct content SEO win.

Bottom line: An accessible site is a better site: for 15–20% of the population with disabilities, for aging users, for mobile users in bright sunlight, and for search engines trying to understand your content. The business case is not either/or. It is cumulative.

// Next steps

Where to start

If you are planning a new site, build accessibility into the design system and component library from week one, not as a pre-launch panic. If you have an existing site, run a baseline audit, fix blockers on your highest-traffic pages first, and establish a maintenance process before the next content push or feature release.

We bake WCAG 2.2 AA into every FirstUp build: from semantic markup and keyboard navigation to contrast, focus management, and assistive technology QA. If you want a clear picture of where your site stands, start a conversation. No pitch deck required.
