Make an AI-built landing page work on mobile

Test the task on a phone

A landing page is not ready for mobile just because its columns stack. A visitor needs to understand the offer, open the form, enter information with the keyboard visible, recover from mistakes, and complete the intended action. Test that journey on the published URL you plan to share.

This guide provides a reader-run verification procedure and a small example based on Pageree’s marketing-site source. It does not claim that an external customer page has passed a device test or that the checks constitute a complete accessibility audit.

Start with the devices and browsers your likely customers use. A responsive desktop preview is useful for layout inspection, but a real phone reveals keyboard, autofill, browser chrome, and external-app behavior that the preview may not reproduce.

Check narrow layout without hiding content

Look for clipped headings, fixed-width panels, oversized images, and controls pushed off screen. W3C’s reflow guidance discusses content fitting a 320 CSS-pixel-wide viewport for vertically scrolling layouts, with exceptions for content that needs two dimensions. Use that as a concrete inspection case, not a reason to make text tiny.

Keep the offer and action readable without horizontal page scrolling. Tables or code examples may need their own controlled overflow. Do not apply overflow-x: hidden to the whole page merely to conceal an element that is wider than the viewport; it can hide content instead of fixing the cause.

Work through the form with the keyboard open

Check	What to try	What to record
Labels	Enter text in every field	Whether the field’s purpose remains visible
Keyboard	Focus email, phone, and longer text inputs	Whether the keyboard suits the field and hides a necessary control
Errors	Submit with a required answer missing	Whether the error identifies a useful correction
Long input	Paste a realistic long project description	Whether text remains editable and the layout holds
Success	Submit a marked test	Whether the page shows the actual next step
Delivery	Open the approved destination	Whether every field arrived intact

Check consent text and its associated controls as carefully as the submit button. A label should help someone activate the intended control, and the page should preserve visible keyboard focus. W3C’s form labels tutorial explains the underlying label association.

An example from this site’s implementation

The marketing-site templates and free tools use a shared responsive stylesheet. Source inspection shows that the two-column tool field layout becomes one column at the narrow breakpoint, demo layouts stack, and fieldsets use min-width: 0 so their contents can shrink within a grid. Longer prose tables have their own horizontal overflow region.

Those are implementation choices, not a recorded device result. The corresponding browser check is to open the prompt generator, narrow the viewport, and complete its form. Then open a quote template and inspect the example. Confirm behavior rather than assuming a media query proves usability.

For your generated page, ask the assistant to explain which element causes any overflow and change that element. A fixed-width form might need width: 100% and a sensible maximum width; a grid item might need to be allowed to shrink. Review the actual code before applying a generic fix.

Keep images from delaying the main action

Use appropriately sized image assets and reserve their dimensions so content does not jump when they load. Load the opening image when it is needed and defer suitable images farther down the page. Inspect the page on a slower connection, especially if the offer relies on a portfolio or gallery.

Do not hide essential service terms in an image. Text that explains price, scope, or the next step should remain readable and accessible when a graphic is unavailable.

Copy this mobile review prompt

Review the mobile journey for [page URL / draft].
Primary task: [submit enquiry / open resource / another real action].
Check narrow layout, heading wraps, image dimensions, visible focus,
labels, keyboard behavior, errors, long field input, and success state.
Separate source-code findings from actions actually tested in a browser.
For each issue, record the viewport/device, reproduction steps,
observed behavior, a targeted correction, and how to retest it.
Do not conceal overflowing content or claim a full accessibility pass.
Prepare fixes in a private draft. After approved publication, verify
the public form and its real delivery destination again.

Keep a short verification record

Record the URL, version, device, browser, task, and result. If an external scheduler opens, verify the scheduling outcome in that service. If a phone link is used, distinguish the link action from a completed call.

Use the launch checklist to keep these checks alongside domain and delivery work. The AI audit guide helps turn observed problems into a focused set of fixes.
