In Switzerland, more than 1.8 million people live with a disability — roughly one person in five. Add the ever-growing share of seniors, plus all the temporary situations — a broken arm, a screen read in bright sunlight, a slow connection on the train between Geneva and Lausanne — and a significant portion of your visitors struggles with a poorly designed website. For an SME in French-speaking Switzerland, an inaccessible site is not just an image problem: it is revenue walking straight to your competitors. The good news: accessibility best practices are concrete, affordable and, as a bonus, they boost your organic rankings. Here is how to get started in 2026, without jargon and without a monster budget.
Why Accessibility Matters to Your SME (Not Just Big Corporations)
Many business owners assume web accessibility is a topic for public administrations or multinationals. That is a mistake, for three reasons.
- The business case: if 5% of your visitors give up because a button is unreadable or a form cannot be completed with a keyboard, and your site generates CHF 200,000 in yearly sales, you are leaving around CHF 10,000 a year on the table. For a brochure site, those are quote requests that never reach your inbox.
- The legal case: the Swiss Disability Discrimination Act (DDA/LHand) already requires accessibility in the public sector, and the European Accessibility Act, in force since June 2025, applies to any Swiss SME selling digital products or services to EU customers. The regulatory direction is clear: better to prepare now than under pressure later.
- The SEO case: Google rewards websites that are well structured, fast and easy to understand. Accessibility criteria overlap heavily with ranking criteria — an accessible site is almost always a better-ranked site.
Two standards worth knowing: WCAG 2.2 (level AA), the international reference, and the eCH-0059 standard for the Swiss context. No need to memorise everything: the three work areas below cover the vast majority of issues we see on SME websites.
Work Area 1 — Contrast: The Most Profitable Fix
The most common flaw we find in our audits: light grey text on a white background, pastel buttons, links barely distinguishable from body text. It looks elegant on the designer's calibrated screen, but it is unreadable for someone with low vision, a senior, or simply anyone checking their phone on a sunny terrace.
The rule is simple and measurable:
- a contrast ratio of at least 4.5:1 for body text;
- at least 3:1 for large headings and interface components (field borders, active icons);
- never convey information through colour alone: a field in error must display an explicit message, not just turn red.
Free tools such as the WebAIM Contrast Checker give you a verdict in ten seconds. The fix then happens in your stylesheet, often within a few hours: an intervention billed at a few hundred francs, for an immediate gain in readability — and therefore conversion — for 100% of your visitors.
Work Area 2 — Text Alternatives: Describing for Humans and for Google
Every image that carries information needs an alt attribute describing what it shows or what it does. This is the text read aloud by the screen readers blind users rely on, and it is also what Google reads to understand your images.
- Describe the function, not the file. For a photo of a Geneva-based fiduciary, write "The team of Exemple SA fiduciary in front of their Geneva offices" rather than "IMG_4382.jpg" or "photo".
- Decorative image = empty alt. A purely graphical flourish needs no description: an empty alt attribute tells the screen reader to skip it, avoiding pointless noise.
- An image button must say what it does. A clickable magnifying glass should announce itself as "Search", not as "magnifier.png".
The SEO benefit is direct: well-written text alternatives that naturally include your keywords improve your presence in Google Images and strengthen the topical relevance of your pages. For a tradesperson, a practice or a local shop, this is a free traffic source your competitors still largely ignore.
Work Area 3 — Keyboard Navigation: The Five-Minute Test
Some of your users never touch a mouse: people with motor impairments, screen reader users, but also power users who live on keyboard shortcuts. Your site must therefore be fully usable with a keyboard alone. Run the test yourself, right now:
- open your site and press the Tab key: do you move from link to link in a logical order?
- can you always see where you are thanks to a visible focus outline? If it was removed "because it looked ugly", that is a real problem;
- can you open the dropdown menus, fill in the contact form and submit it with Enter, without ever touching the mouse?
- can you close a pop-up window with Escape?
If you get stuck somewhere, part of your audience gets stuck there too — permanently. The fixes (tab order, visible focus, skip links) are targeted technical interventions, rarely heavy on a WordPress brochure site or a small online shop.

Accessibility and SEO: Why Google Loves Accessible Websites
Google does not "see" your website: it reads it, exactly like a screen reader does. Everything that helps a blind person understand your page also helps the search engine rank it. In practice:
- A clean heading structure: a logical H1-H2-H3 hierarchy lets screen readers jump from section to section — and lets Google grasp how your content is organised.
- Text alternatives: extra indexable content and better rankings in Google Images.
- Video captions and transcripts: your audio content becomes indexable text, often rich in long-tail keywords.
- Better engagement signals: a readable, navigable site lowers bounce rates and increases time on page, two signals search engines interpret positively.
- Performance: accessibility best practices go hand in hand with semantic, lightweight code, which supports your Core Web Vitals.
In other words, every franc invested in accessibility works twice: once for your users, once for your visibility. In a Swiss-French market where page one of Google often comes down to small details, this is a competitive edge most of your competitors are not using yet.
What Does It Actually Cost?
Here are the price ranges we observe in French-speaking Switzerland in 2026:
- Self-audit with free tools: CHF 0 and about two hours of your time (see the checklist below).
- Basic fixes (contrast, text alternatives, focus, forms) on a brochure site: typically between CHF 800 and CHF 2,500 depending on the size of the site.
- Full professional audit against WCAG 2.2 AA, with a prioritised report: between CHF 1,500 and CHF 4,000 for an SME website.
- A redesign with accessibility built in from day one: almost no extra cost when planned from the start — it is the late catch-up that gets expensive.
Weigh those amounts against the value of additional customers, the SEO traffic gained month after month and the regulatory risk avoided. For most SMEs, the basic fixes pay for themselves within a few months.
Your Free Quick Audit: The 15-Minute Checklist
You do not need to be a developer to run a serious first diagnosis:
- Tab test (3 min): navigate your homepage with the keyboard, from top to footer. Note every blocking point.
- Lighthouse (3 min): in Chrome, right-click your page, "Inspect", open the Lighthouse tab, tick "Accessibility": you get a score out of 100 with a list of detected issues.
- Contrast (3 min): run your main colours (text, buttons, links) through a free contrast checker.
- Images (3 min): check that each of your key images has a relevant text alternative.
- 200% zoom (3 min): enlarge the page to 200% in your browser: does the site remain usable, with no clipped text or overlapping elements?
A Lighthouse score below 90 or a dead end during the Tab test? You now know where to focus your efforts — and you are already ahead of the majority of SME websites.
Where to Start
Web accessibility is neither a luxury nor a bureaucratic monster: it is a set of measurable best practices that widen your audience, secure your compliance and durably strengthen your SEO. Start with the 15-minute audit, fix contrast and text alternatives, then tackle keyboard navigation. At Digital Swiss Agency, we build these standards into every website we design in Geneva, and we offer a free quick audit of your current site: you walk away with a prioritised list of fixes, quantified in francs and working days. Enough to turn a perceived obligation into a genuine growth lever.
