Graphic about seven web design principles, with a wireframe sketch.

Conversion design examines whether the website helps a visitor take an appropriate next step. A design principle can identify a possible obstacle, but it cannot promise a conversion increase. Define the action and check the actual journey before judging the result.

1. Give the page a clear hierarchy

Make the main topic, supporting information and next action easy to distinguish. Group related items and use headings that describe their sections. Space can help show relationships; it does not need to follow a universal rule-of-thirds placement.

2. Design with the real content

Plan the service explanation, conditions and evidence before finalising the layout. Test realistic headings, prices where applicable and error messages. Empty design boxes can hide problems that appear only when the actual content is added.

3. Keep behaviour and terminology consistent

Use the same label for the same action. Preserve familiar navigation and control behaviour across the journey. Brand colours and imagery should support understanding without making a link or form difficult to recognise.

4. Make the next step accurate

A label such as “Request an estimate” should describe what follows. Put important conditions before the person commits information or money. Offer supporting information where readers need it, without competing buttons that obscure the main task.

5. Add interaction for a reason

A calculator, selector or demonstration can help when the answer depends on the visitor’s choices. A decorative animation may add loading and accessibility work without solving a problem. Keep useful content and controls available when an enhancement fails.

6. Check contrast and focus

Use readable foreground and background combinations, visible keyboard focus and labels that do not depend on colour alone. Check the actual button, link and error states. A colour’s supposed emotional meaning is not evidence of a conversion effect.

7. Use images that explain

Choose genuine or appropriately licensed media relevant to the offer. Add useful alternatives for informative images and avoid presenting decorative stock imagery as proof. Keep essential facts available in text.

Check the whole conversion journey

Illustrative example: a quote form may fail because its required field has no clear label, even though the button is visually prominent. Fix the label, test the error and confirmation states, and verify authorised receipt before evaluating enquiry quality.

Repeat the task on mobile and by keyboard. Record the issue, proposed correction and evidence needed to assess it. Compare meaningful outcomes using consistent definitions rather than assuming a visual change caused a sale.

Use the broader website improvement checklist to review navigation, content and forms together.
