What you’ll take away

  • Match the landing page to the audience and promise that brought the visitor there.
  • Use concrete product evidence before adding more persuasion.
  • Review the full enquiry or trial journey on a real mobile device.

Decide what this page needs to accomplish

A landing page should help a particular visitor make a particular decision. Write down the audience, the entry source, the offer, and the desired next step before reviewing the design. A page supporting a broad educational article may need a different invitation from a page reached through a high-intent product search.

Choose one primary conversion journey, such as a qualified demo request or a self-serve trial. Secondary links can still help people evaluate the product, but they should not leave the visitor guessing which action matches their needs. Explain what follows the click, especially when the next step involves a sales conversation.

Check the headline and opening explanation

Read the headline without the rest of the page. Can a suitable buyer work out the product’s purpose and recognize a relevant outcome? Then read the supporting sentence. It should add useful context, such as the intended user or workflow, rather than repeat the same promise with different adjectives.

For an illustrative reporting tool, “Build a weekly client report from your existing campaign data” tells a reader more than “Unlock intelligent business performance.” The first version still needs accurate detail, but it gives the designer and product team a specific experience to support.

Replace decorative proof with product evidence

A screenshot, short walkthrough, or annotated example can answer a question that a stock photograph cannot. Show what the user starts with, what happens inside the product, and what they receive. Use genuine product screens or label illustrative examples clearly so the page does not imply an unavailable feature.

Place evidence near the claim it supports. If you use client names, quotations, or results, confirm permission and explain their context. A customer count from a previous business or a campaign result from an unrelated service should not silently become proof for a new software product.

Make the form and next step understandable

Ask for the information needed to deliver the next step. Each additional question should have a purpose, whether that is routing an enquiry or preparing a useful demonstration. Do not remove qualification fields simply to make the form appear shorter if that leaves the team with unworkable enquiries.

Use visible labels, understandable instructions, and clear error feedback. W3C’s forms guidance recommends identifying controls with labels. Review what happens after submission too: the confirmation should say what was received and what the visitor can reasonably expect, without promising a response time the team cannot maintain.

Review mobile use and image loading

Test the page at narrow widths and through the complete form journey. Check that the headline remains readable, key information is not hidden, and the primary action is usable without precision tapping. Open navigation menus and validation messages rather than judging the mobile experience from a static screenshot alone.

Large hero images and video can delay the point at which the page feels useful. Google’s web.dev guidance treats the loading of the largest visible image or text as a measurable performance concern. Serve an appropriately sized image, reserve its space, and review actual page behavior instead of assuming that a high-resolution upload is automatically a better experience.

Measure the outcome with context

Define the event that represents completion, then distinguish that event from the quality of the resulting lead or trial. A click on a demo button is not the same as a completed request, and a request is not necessarily a suitable sales opportunity. Make those definitions visible in the reporting brief.

When changing the page, record what changed and when. Consider the audience, channel mix, and amount of evidence available before crediting the design for a movement in conversion rate. If traffic is limited, address clear usability problems first and be honest about what the numbers can establish.

Put this guide to work

  • Confirm the audience, entry promise, and primary next step.
  • Show the product working on a relevant task.
  • Check permission and context for every proof point.
  • Label form fields and test success and error states.
  • Review the page on mobile and inspect large image loading.
  • Separate completed actions from qualified outcomes.
