Imagine someone has already decided to contact your business. They understand your offer, like the work and reach the enquiry form. Then the keyboard focus disappears. A required field has no clear label. An error appears in a colour they cannot distinguish. The business has attracted the right person and made the final step unnecessarily difficult.
Before spending more to bring people to that form, check whether they can use it. An extra call-to-action button will do little for someone who cannot read the instructions, reach a field or understand how to correct an error.
Try completing one important task.
Choose something commercially important: requesting a quotation, finding a service, booking a consultation or completing a purchase. Follow that task using a keyboard. Check whether the current position is visible, the order makes sense and every essential control can be reached. Then increase the text size and review the same task again.
W3C’s introductory accessibility checks cover areas including keyboard access, focus, headings, contrast, text resizing and forms. They are a starting point, not a complete accessibility assessment. Passing a small automated checklist should never be presented as proof that every visitor can use the service.
Make the next step understandable.
A button labelled “Continue” might be clear in one context and vague in another. An enquiry button can explain whether it opens an email app, submits a request or starts a conversation. Error messages should help someone recover: identify the field, explain the issue and preserve the useful information they already entered.
For a business owner, this creates a practical review brief. Ask the team to demonstrate the complete journey, including an incorrect entry and the recovery from it. Do not approve only the empty form and the ideal success screen. The moments between those states are where uncertainty often appears.
Measure access and business outcomes separately.
W3C’s business case explains how accessibility can extend reach and improve the broader user experience. That does not justify promising a particular sales increase. The commercial result depends on the offer, traffic, pricing, trust and many other factors.
Track useful signals without inventing causation. Are people reaching the form? Where do they stop? Are support questions repeating the same confusion? Pair those observations with direct usability testing, including people with disabilities where appropriate. A conversion chart can identify a problem area, but it cannot tell the whole story of who was unable to participate.
What to ask before sign-off
Ask to see the important journeys demonstrated, including a form with an error in it. Can the person recover without starting again? Record which checks were completed and which barriers still need work. Keep that record with the project so the next content change or new feature can be reviewed against the same expectations.
