Serve phones the same content

Give phone visitors the same content, links, metadata and structured data as desktop visitors. Google indexes the phone version of every page.

By Erik Bergstedt, Agent Wranglers. Updated 20 October 2026.

How to do it

Use one responsive page for every screen. Never drop text, links, images or JSON-LD on narrow screens. If content folds away on phones, keep it in the HTML, such as inside <details>. Never serve a separate cut-down mobile page.

Example

ua_phone='Mozilla/5.0 (Linux; Android 14; Pixel 8) Mobile'
diff <(curl -s -A "$ua_phone" https://example.com/pricing | grep -o '<a href="[^"]*"' | sort) \
     <(curl -s https://example.com/pricing | grep -o '<a href="[^"]*"' | sort)

How to check

Fetch each page type once with a phone user agent and once with a desktop one. The h1, link count, canonical and JSON-LD match.
