Mobile viewport
A viewport meta tag is the basic signal that the layout is meant for phones — still a ranking and usability prerequisite.
Pass condition in our engine: A meta name=viewport tag is present.
1. Problem description
Without width=device-width, mobile browsers render a desktop layout and pinch-zoom. Google’s mobile-first index then sees an unusable page. Interstitials and tiny tap targets usually follow.
2. Most common causes
- A desktop-only HTML email-style template.
- The <head> was trimmed and the viewport meta was dropped.
- A SPA shell forgets to set viewport in the server-rendered HTML.
3. How to fix it
- Add <meta name="viewport" content="width=device-width, initial-scale=1">.
- Test the page in Chrome device mode and on a real phone.
- Avoid user-scalable=no unless you have a strong accessibility alternative.
