An accessible website removes barriers that stop people from reading, navigating or completing an action. It helps customers who use screen readers, keyboards, captions, zoom or voice controls—but it also makes everyday tasks clearer for people using a phone in bright light, dealing with a temporary injury or simply trying to buy quickly.

For Australian small businesses, the practical target is usually WCAG 2.2 Level AA. WCAG is the international accessibility standard published by the World Wide Web Consortium. The Australian Government’s Digital Transformation Agency now points to WCAG 2.2 in its own accessibility guidance.

Accessibility is not a one-click badge and it is not an automatic Google ranking boost. It is a combination of design, code, content and ongoing quality control. Many good accessibility practices—clear headings, descriptive links, useful alternative text and predictable navigation—also help search engines understand pages and help users convert.

Start with the journeys that make money

Do not begin with a random list of technical errors. First identify the actions customers must be able to complete: find a service, compare products, submit an enquiry, add to cart, pay, book or call.

Test those journeys at 200% zoom, on a phone and using only the keyboard. If a visitor cannot see where focus has moved, open a menu, choose a variation or understand an error message, the journey is not reliably accessible.

Seven WCAG 2.2 checks worth doing now

1. Give every page a clear structure

Use one descriptive H1 and a logical sequence of H2 and H3 headings. Headings should describe the section that follows; they should not be chosen only because they look a certain size.

2. Check colour contrast and visible focus

Text and important controls need enough contrast against their background. Keyboard users also need a clear focus indicator on links, buttons, menus and form fields. WCAG 2.2 added criteria that pay closer attention to focus visibility and obstruction.

3. Make images understandable

Write concise alt text when an image communicates information. Use empty alt text for purely decorative images. Do not stuff keywords into alt text: describe the useful content in context.

4. Label forms and explain errors

Every field needs a persistent label. Error messages should say what went wrong and how to fix it. Never rely on colour alone to indicate an error.

5. Add captions and transcripts

Caption videos with accurate spoken content and meaningful sounds. A well-edited transcript also gives visitors another way to consume the material and creates indexable text for search.

6. Make tap targets forgiving

Small or tightly packed controls are hard to use on mobile and for people with limited dexterity. WCAG 2.2 includes a minimum target-size criterion, with defined exceptions. Review menu icons, carousel dots, cookie controls and checkout buttons.

7. Test with people and assistive technology

Automated tools find only some problems. Combine a scanner with keyboard testing, screen-reader checks and, where possible, testing by people with disability. Prioritise blockers in revenue and enquiry journeys first.

Accessibility and SEO: what is genuinely connected?

Google does not publish a blanket “WCAG ranking factor”. The defensible connection is practical: well-structured content can be easier to crawl and understand; descriptive titles and links improve context; captions and transcripts create searchable content; and usable mobile journeys reduce friction after the click.

Treat accessibility as customer experience and risk management, with SEO benefits where the practices overlap. Avoid selling it as a shortcut to rankings or guaranteed legal compliance.

A sensible 30-day improvement plan

In week one, audit the homepage, primary service or category pages and the main conversion path. In week two, fix keyboard blockers, form labels, contrast and heading structure. In week three, improve media alternatives and templates. In week four, retest, document standards for future content and assign ownership.

The result should be a website that more people can use and your team can keep accessible as it changes.

Frequently asked questions

Does every Australian business website have to meet WCAG 2.2? Legal obligations depend on context and should be assessed with qualified advice. WCAG 2.2 is a strong current benchmark for accessible design; do not present an automated score as a legal opinion.

Can a plugin make a website accessible? A plugin may help with a narrow issue, but it cannot reliably repair content structure, keyboard behaviour, forms and third-party components across an entire site.

Will accessibility improve Google rankings? Not automatically. Several accessibility practices overlap with sound technical SEO and better user experience, but compliance itself should not be promised as a direct ranking boost.

Evidence note: No public evidence proves that WCAG conformance directly raises rankings or conversions for every site. Those outcomes must be measured after implementation.
