How Digital Accessibility Improves Your SEO

Digital accessibility means making digital content and services understandable and usable by everyone, including people with disabilities. This inclusive approach significantly enhances your organic search ranking by optimizing the user experience and technical structure of your site. The RGAA — the French Web Accessibility Framework — defines the standards to meet legal obligations while improving your SEO.

Good accessibility practices directly strengthen several key SEO factors. A properly structured semantic HTML helps search engine crawlers better understand your content. Image alt tags enrich Google’s contextual understanding while assisting screen readers.

Keyboard navigation and explicit links reduce bounce rates by allowing all users to efficiently browse your site. Sufficient contrast and text readability increase time spent on pages.

Diagnostic tools often reveal that high-performing websites also score high on accessibility, as both aim for the same goal: offering an optimal user experience for all visitors.

Google prioritizes sites that provide an optimal user experience for everyone. Search engines analyze behavioral signals similar to those promoted by universal accessibility: longer sessions, smooth navigation, and easily understandable content.

A semantically correct HTML code makes it easier for crawlers to index your pages. Hierarchical headings help algorithms structure information better, while alternative descriptions enrich the semantic context of your pages.

Accessibility also delivers measurable technical benefits. Websites that comply with RGAA standards generally load faster and offer stronger mobile compatibility. These factors directly impact your search ranking, creating a virtuous cycle between inclusion and performance.

• Keyboard navigation allows users to browse without a mouse, reducing abandonment.
• Adequate color contrast makes reading easier for everyone, especially on mobile.
• Forms with explicit labels reduce input errors and speed up conversions.
• Descriptive links replace vague “click here” prompts by clearly indicating their destination.
• Video transcripts enrich indexable text content while helping deaf or hard-of-hearing users.
• Clear heading hierarchy (H1–H6) structures information for quicker reading.
• Larger clickable areas improve touch interaction on smartphones and tablets.

• Optimized loading times keep 91% of mobile visitors engaged.
• Enhanced content readability encourages full-page reading and longer sessions.
• Consistent navigation menus naturally guide visitors to other pages.
• Accessible call-to-actions increase engagement and conversions.
• Compatibility with assistive technologies expands your loyal, engaged audience.
• Error-free forms prevent frustration and page abandonment.
• Logical content organization encourages deeper exploration.

• 12 million people in France have disabilities — a significant, often overlooked market.
• Seniors over 60 benefit from improved accessibility for easier navigation.
• Mobile users appreciate enhanced contrasts and larger touch areas.
• Temporary disabilities (broken arm, eye strain) are also accommodated.
• An accessible site can capture up to 20% more audience according to European statistics.
• Search engines better index structured content, attracting more qualified traffic.
• Assistive technologies can recommend accessible sites to their users.

Digital accessibility makes your web content understandable and usable by all, especially people with disabilities. Beyond legal compliance, a well-implemented accessibility strategy greatly improves your search engine ranking. RGAA-compliant websites enjoy better UX, lower bounce rates, and broader audiences — all key factors valued by Google.

The Référentiel Général d’Amélioration de l’Accessibilité is France’s official technical framework for evaluating and ensuring digital accessibility. Published by DINUM since 2009, it translates international WCAG standards into actionable criteria.

Version 4.1.2 defines 106 control criteria across 13 technical themes. Each criterion includes specific tests enabling developers and auditors to objectively verify website or mobile app compliance.

RGAA is based on the European standard EN 301 549, ensuring alignment with continental norms. This operational method turns abstract inclusion principles into measurable technical requirements, making accessibility implementation far more practical.

• Perceivable: Information must be presented in ways that all users can perceive.
• Operable: Interfaces must function with multiple navigation modes such as keyboard or voice control.
• Understandable: Content and interface behavior must be clear to all cognitive levels.
• Robust: Code must remain compatible with current and future assistive technologies.

These four “POUR” pillars form the foundation of all 106 RGAA criteria, guiding developers with concrete, practical directives.

Digital accessibility ensures that your web content and services are understandable and usable by everyone, including people with disabilities. This inclusive approach naturally improves your Google ranking by optimizing UX and technical structure. Meeting RGAA and French legal obligations can transform your online visibility while broadening your audience.

• Visual impairments: Require screen readers, strong contrasts, and image alt text.
• Hearing impairments: Need subtitles, transcripts, and visual alerts replacing sounds.
• Motor disabilities: Need full keyboard navigation, larger clickable areas, and compatibility with adaptive devices.
• Cognitive impairments: Benefit from simple language, consistent navigation, and reduced distractions.

• Screen readers (NVDA, JAWS) convert text to speech.
• Braille displays render text as tactile characters.
• Digital magnifiers enlarge and invert contrast as needed.
• Switch devices allow control via simple head or pressure movements.
• Voice recognition (Dragon) turns spoken commands into computer actions.
• Eye-trackers let users control the cursor with gaze.
• Virtual keyboards adapt to reduced motor abilities.

Accessibility goes beyond RGAA compliance. It directly improves your SEO by optimizing UX and site structure. Learn how to turn this legal requirement into a real SEO asset.

Effective June 28, 2025, the EAA requires all EU businesses to make digital services accessible, expanding obligations beyond the public sector.
It covers e-commerce, banking, transport, and media. Only micro-enterprises (<10 employees and <€2M turnover) are exempt.
France implemented it via the March 9, 2023 law, aligned with EN 301 549. ARCOM and DGCCRF oversee compliance, marking a new era for private-sector digital inclusion.

• ARCOM: fines up to €50,000 per non-compliant service (renewable every six months).
• DGCCRF: up to €75,000 or 1% of turnover for private companies.
• ARCEP: monitors telecoms; AMF: oversees financial services.
• Public bodies risk €25,000 for missing accessibility declarations.

Audits include both automated and manual checks, with prior warnings before penalties.

Public-access establishments must now ensure both physical and digital accessibility. Websites, mobile apps, and kiosks fall under the same EU regulations since 2025.

This applies to online booking, remote orders, and digital ticketing (restaurants, cinemas, museums, etc.). A physically accessible venue must also offer a digitally inclusive interface, ensuring continuity for all users.

This official document certifies compliance of your digital services. ERP managers must submit it to authorities alongside their physical accessibility certificate.

Small businesses may self-evaluate, while larger ones need validation by certified auditors. The certificate must list establishment details, covered digital services, and audit reports proving RGAA compliance.

Digital accessibility audits — guided by RGAA — improve both compliance and SEO. Accessible websites deliver better UX, lower bounce rates, and wider audiences.

De Bussac Multimédia offers specialized accessibility audits:

Tools like WAVE, axe DevTools, and Lighthouse automatically check around 50 RGAA criteria — missing alt text, contrast issues, and HTML structure errors.
However, they cover only 20–30% of total accessibility criteria; 70% still require human evaluation.

Integrating these checks into your development workflow (e.g. via Pa11y or browser extensions) ensures continuous compliance before deployment.

The official RGAA grid includes 106 criteria across 13 categories. Each has detailed technical tests and examples to ensure reproducibility.

The downloadable Excel model automatically calculates per-page and overall compliance rates.
DINUM’s Ara Numérique tool assists experts in generating reports.
Manual evaluation remains essential, as 70% of criteria require expert human judgment.
