A business website can look polished and still be difficult for many people to use. Text may be hard to read, navigation may depend entirely on a mouse, images may provide no useful information to a screen reader, or a form may not clearly explain what went wrong.

Web accessibility addresses those barriers. It involves designing and building websites so that people with visual, auditory, physical, cognitive, and neurological disabilities can perceive the content, understand it, navigate it, and complete important tasks.

Accessibility is also practical website design. Many improvements that help people with disabilities make a site clearer and easier for everyone, including older visitors, people using mobile devices, and anyone dealing with poor lighting, a temporary injury, or a slow connection.

Accessibility starts with ordinary website decisions

Accessibility is sometimes treated as a specialized feature that can be added after a website is complete. In practice, many of the most important decisions happen much earlier.

They are part of choosing colours, organizing content, creating navigation, labelling forms, writing links, and deciding how interactive elements will work. Considering these issues during the original website design process is usually more practical than trying to correct a large collection of problems later.

The Web Content Accessibility Guidelines, commonly called WCAG, provide an internationally recognized framework for accessible web content. The guidelines are extensive, but a business owner does not need to understand every technical success criterion to recognize the basic principles of a usable website.

Make text easy to see and read

Text needs enough contrast against its background. Light grey text on white, dark text over a busy photograph, or coloured text on a similar-coloured button may fit a visual style but still be difficult to read.

Contrast should be checked rather than judged by eye alone. This applies to normal body text, headings, links, buttons, form labels, error messages, and text placed over images or gradients.

Readable typography also depends on more than contrast. A practical website should use:

text that is large enough to read comfortably
clear typefaces for paragraphs and important instructions
reasonable spacing between lines and paragraphs
shorter paragraphs that are easy to scan
layouts that remain usable when text is enlarged

Visitors should not have to zoom repeatedly, rotate their phone, or struggle with decorative typography to understand basic business information.

Give images useful text alternatives

Alternative text, usually called alt text, describes the purpose or relevant content of an image for people who cannot see it. Screen-reading software can announce this description in place of the image.

Good alt text depends on context. A photograph of a completed renovation might identify the type of project and its main visible feature. A product image may name the product and distinguish the version shown. A chart may require a concise description of the information it communicates.

Alt text should not be stuffed with search phrases or begin with unnecessary wording such as “image of.” It should communicate what the visitor needs to know in that location.

Decorative images are different. When an image adds no information and exists only for presentation, it should normally be ignored by assistive technology rather than burdening the visitor with a meaningless description.

Ensure the site works without a mouse

Some people navigate websites with a keyboard because they cannot use a mouse or pointing device. Others use assistive technologies that rely on the same underlying keyboard behaviour.

A visitor should be able to move through menus, links, buttons, form fields, popups, and other controls using the keyboard. The currently selected element also needs a visible focus indicator so the visitor can tell where they are on the page.

Keyboard testing often reveals problems that are easy to miss during ordinary visual review. A menu may open but provide no way to reach its links. A popup may trap the visitor inside it. A custom button may respond to a mouse click but not a keyboard command.

These are functional problems, not minor presentation details. When a visitor cannot reach a control, the related service or information may be unavailable to them.

Use headings to create a meaningful structure

Headings should organize a page into a logical outline. The main page heading identifies the overall subject, while lower-level headings divide the content into useful sections and subsections.

This helps sighted readers scan the page, but it also allows screen-reader users to move through the content by heading. A page that uses bold text merely to imitate headings may look organized without providing the underlying structure assistive technology needs.

Heading levels should follow a sensible order. They should not be selected because one happens to have the preferred font size. Visual appearance belongs in the website’s stylesheet, while heading tags communicate the structure of the content.

Clear structure also includes meaningful page titles, properly organized lists, understandable labels, and a reading order that still makes sense when the visual layout is removed.

Write links that explain where they go

Link text should make sense on its own. Repeated links labelled “click here,” “read more,” or “learn more” provide little context, especially when someone is reviewing a list of links with a screen reader.

A descriptive link such as “review our website redesign services” explains its destination before the visitor activates it. Clear link wording also helps people scanning a page quickly or deciding whether the destination is relevant.

Links should be visually recognizable as links, and colour should not be the only way they are distinguished from surrounding text. Their focus and hover states should also remain visible.

Build forms that explain what is required

Contact forms, quote requests, newsletter signups, and checkout screens are common sources of accessibility problems.

Every field needs a clear label that remains available while the visitor is entering information. Placeholder text inside a field is not a reliable replacement because it disappears when typing begins and may have poor contrast.

Forms should also:

identify required fields clearly
provide instructions before they are needed
use suitable field types and input controls
explain errors in plain language near the affected field
avoid relying only on red borders or another colour to indicate a problem
allow the visitor to review and correct information without losing their work

An error message such as “There was a problem” leaves the visitor guessing. “Enter an email address in the format name@example.com” gives them something useful to act on.

Do not rely on colour, sound, or motion alone

Colour can support communication, but it should not carry the full meaning. A chart that distinguishes categories only through red and green may be difficult for someone with colour-vision deficiency. A form that marks invalid fields only in red may not communicate the problem clearly.

Important information should also be conveyed through text, labels, patterns, icons, or another understandable indicator.

Video and audio content require similar consideration. Captions help people who are Deaf or hard of hearing, but they are also useful in noisy settings or anywhere sound cannot be played. Transcripts can make spoken information easier to review and search.

Motion, animation, and automatically moving content should be used carefully. Visitors should not be forced to race against changing slides, and distracting motion should not interfere with reading or navigation.

Accessibility is an ongoing responsibility

A website can become less accessible over time even when it was built carefully. New images may be uploaded without alt text. A third-party booking system may introduce controls that cannot be reached by keyboard. New colour combinations or content layouts may reduce readability.

Accessibility should therefore be included in routine website reviews and content updates. Automated testing tools can identify certain issues, including some contrast, labelling, and structural errors, but they cannot determine whether every description is useful or whether a process makes sense to a real person.

Manual review remains important. Basic checks include navigating with a keyboard, enlarging the text, reviewing heading order, checking forms, and considering whether instructions remain understandable without relying on visual position or colour.

Legal requirements depend on the organization

Accessibility requirements vary by jurisdiction, industry, organization type, and size. Federally regulated organizations may have obligations under the Accessible Canada Act and related regulations. Ontario has specific accessibility requirements that apply to many businesses, non-profits, and public-sector organizations. British Columbia is also developing accessibility standards under the Accessible British Columbia Act.

This means there is no single legal statement that applies equally to every Canadian business website. Organizations should obtain appropriate legal or compliance advice when they need to determine their exact obligations.

Even where a particular technical standard is not mandatory, ignoring accessibility can create avoidable risk. An inaccessible website may prevent someone from obtaining information, requesting service, applying for a position, or completing a transaction. It can also lead to complaints, remediation costs, and damage to the organization’s reputation.

Accessibility belongs in good website planning

A perfectly accessible website is not created by adding a badge, installing a toolbar, or running one automated scan. Accessibility depends on the design, code, content, and ongoing management of the site.

For a new website, the practical approach is to consider accessibility while the navigation, design system, page templates, forms, and content structure are being created. For an older site, a planned website redesign provides an opportunity to correct underlying problems instead of adding temporary workarounds.

The result is a website that is clearer, more flexible, and usable by more of the people the business is trying to reach.
