Web Accessibility on Your Landing Page: A Practical WCAG Guide

Web accessibility means designing pages that anyone can perceive, understand, and operate, whether or not they have a visual, hearing, motor, or cognitive disability, and whichever device or assistive technology they use. On a landing page, it means no one is left out of the form or the buy button because of an avoidable obstacle.

This guide explains what web accessibility is, who it affects, what the legal framework in Spain and the European Union says, which basic guidelines to apply, and how to review them. Your page can have an excellent offer and still lose visits you will never know existed.

What is web accessibility and who does it affect?

An accessible website works for people with different abilities and in different situations. The international reference standard is the Web Content Accessibility Guidelines, known as WCAG, which are organized around four principles: content must be perceivable, operable, understandable, and robust.

The affected audience is larger than it looks. The World Health Organization estimates that around one in six people in the world lives with some form of disability. Add people who are aging, people with a temporary injury such as a broken arm, or people looking at a phone in sunlight with low contrast. Accessibility is not a minority issue: it improves the experience for almost everyone.

When a landing page is not accessible, the visitor does not complain: they simply leave. Someone using a screen reader who finds a button with no name, or someone navigating with a keyboard who cannot reach the form, leaves no trace in your stats beyond a visit that does not convert.

What do the rules in Spain and the European Union require?

The legal framework is context worth knowing, although each case depends on the activity and the size of the company; if you have any doubt, consult a legal specialist.

At the European level, the technical reference standard is EN 301 549, which for web content points to the WCAG guidelines. On the other hand, the European Accessibility Act sets accessibility requirements for certain products and services, including some e-commerce services. Its obligations apply from 28 June 2025, and Spain has incorporated the directive into its legal system.

The directive itself provides exemptions, for example for microenterprises that provide services. Even so, the fact that the law does not require you to act does not mean it is wise to ignore the topic: customers, platforms, and partners increasingly expect accessible websites, and getting ahead is cheaper than fixing later.

Which basic WCAG guidelines should your landing page meet?

You do not need to master the whole standard to improve a lot. Five points cover most of the obstacles that appear on a capture or sales page.

• Sufficient contrast. WCAG asks for a contrast ratio of at least 4.5 to 1 for normal text and 3 to 1 for large text. Light gray on white looks elegant, but it is unreadable for many people.
• Alternative text. Images with meaning need a short description a screen reader can read; purely decorative ones should be left empty so they do not get in the way.
• Keyboard navigation. Everything that can be clicked with a mouse must be reachable with the Tab key, with a visible focus indicator, including the buy button.
• Form labels. Each field needs a visible label associated in the code, not only placeholder text that disappears when you type.
• Touch target size on mobile. Buttons and links should be large enough and spaced apart. WCAG 2.2 sets a minimum of 24 pixels, and around 44 is recommended for a comfortable tap.

Beyond these five points, use headings in a logical hierarchy, write links that make sense on their own, such as “Download the guide” instead of “Click here,” and do not convey information through color alone.

How do you make the form and the mobile version accessible?

The form is the point where most conversions are lost to accessibility problems. Besides labels, error messages should explain what happened and how to fix it, not only mark a field in red. Many of the guidelines for reducing friction on the capture form are, in practice, accessibility improvements.

On mobile, the challenge is the finger. A small button or one stuck to another causes missed taps that affect everyone, and especially people with tremors or limited motor precision. If you want to review the rest of the design, there is a guide on how to prepare a landing page for mobile on a 4G connection that complements these guidelines.

Also check that the text can be enlarged up to two hundred percent without the layout breaking, and that the page does not lock screen rotation. These are details that cost almost nothing at design time and that prevent frustration.

How do you check your landing page’s accessibility step by step?

Measuring accessibility does not require a specialist team. With free tools and a few manual tests you can catch a large share of the most common problems. This list works as a review checklist.

1. Run an automatic audit with a free tool such as Lighthouse, built into Chrome, or with WAVE or axe DevTools, and note contrast and label errors.
2. Walk through the page with the keyboard only, using Tab and Shift plus Tab, and check that you can reach every element and that you always see where the focus is.
3. Listen to the page with a screen reader, such as NVDA on Windows or VoiceOver on Mac and iPhone, and check that buttons, images, and fields are announced in a way that makes sense.
4. Enlarge the text and try the landing page on a real phone, checking that buttons can be tapped without errors and that nothing is cut off.
5. Fix first whatever blocks a key action, such as the form or the buy button, and leave smaller details for later.

Automatic tools detect only part of the problems, so manual tests are essential. Repeat the review every time you change the design or add content.

How does an accessible landing page help SEO and conversion?

Many accessibility practices overlap with SEO: hierarchical headings, alternative text, descriptive links, and clean code. They also support automatic reading, which matters more as AI search engines grow; we cover that in the guide to generative engine optimization. Well-structured content is easier to interpret both for a person with a screen reader and for a system that summarizes pages.

On conversion, the effect is direct: if more people can complete the form, more people convert. A light page also helps people on modest devices or slow connections, and load speed is part of everyone’s experience. It is worth measuring the effect of each change with an A/B test, for example comparing a higher-contrast button with the original.

If you do not want to start from scratch, a landing page builder like Atomicat lets you build pages with an ordered structure and editable text, so you can review contrast, labels, and buttons without touching code.

What is the difference between an accessible landing page and one that is not?

The comparison shows that accessibility is not a cosmetic extra, but part of the quality of the page.

| Aspect | Landing page without accessibility | Accessible landing page |

| --- | --- | --- |

| Contrast and text | Light gray on white, small type that is hard to read | Sufficient contrast and text that enlarges without breaking the layout |

| Keyboard and screen reader | Buttons and fields unreachable or unnamed | Everything is reachable with Tab and announced in a way that makes sense |

| Form | Fields without labels and errors only in red | Visible labels and clear error messages |

| Result | Visitors who leave without a word and a risk of non-compliance | More people complete the action and the page is easier to understand |

The cost of doing it well from the start is small compared with redesigning a page that is already live.

Frequently asked questions

What is web accessibility?

It is the design of websites that anyone can perceive, understand, and use, regardless of their abilities or the technology they use. The reference standard is the WCAG guidelines.

What are the most important accessibility guidelines?

The basics are sufficient color contrast, alternative text on images, full keyboard navigation, clear labels on forms, and buttons large enough on mobile. These are the ones that prevent the most obstacles on a landing page.

How can I measure my page’s accessibility?

Combine a free automatic audit, such as Lighthouse, WAVE, or axe, with manual tests: walk through the page with a keyboard and listen to it with a screen reader. Automatic tools do not catch every problem.

Is web accessibility mandatory in Spain?

It depends on the activity and the size of the company. The European Accessibility Act requires certain services, including some e-commerce services, to meet requirements from 28 June 2025, with exemptions for microenterprises. Check your case with an advisor.

Does accessibility improve SEO and conversion?

Yes, to a large extent, because it shares practices with SEO, such as ordered headings, alternative text, and descriptive links. In addition, a page that more people can use converts more visitors.
