Mobile SEO in Japan: Make the Whole Website Usable on a Phone

Keep essential content available on mobile

Google documents that it uses the mobile version of a site’s content for indexing and ranking. Its mobile-first guidance recommends equivalent primary content and metadata across mobile and desktop versions, with resources available to crawlers.

Test the task, not just the screen size

Open your site on a phone and act as a new customer. Find a service, read its details, open the contact page, and complete the form. Note where text, navigation, or overlays make the task difficult.

• Use readable text and sufficient contrast.
• Check that controls have comfortable touch targets.
• Keep service descriptions and important links available at narrow widths.
• Reserve space for images so content does not jump as the page loads.
• Make validation messages understandable and connected to the relevant fields.

Review after real content is added

A layout that works with placeholder text may fail with a long service name or a Japanese translation. Check realistic content and slower connections. Record measurements for the pages that matter rather than assuming every page loads at the same speed.
