App install banner configuration missing — the fix
This site has a native app but lacks the web app manifest and service worker configuration needed to trigger browser-native app install banners.
Where this fits: mobile in SEO
Google indexes the mobile version of your site — desktop is the afterthought, not the other way round. Mobile issues (missing viewport, tap targets too close, content wider than the screen, intrusive interstitials) directly gate rankings for every query. With most traffic on phones, a mobile problem is not a subset of your audience — it is your audience.
Why app install banner configuration missing hurts your rankings
Browser-native app install banners are more effective and less intrusive than custom app download interstitials. Google penalizes pages that show intrusive interstitials (including app install pop-ups), so using the native banner API is the recommended approach for promoting your app.
This is an advisory finding: not a defect, but an opportunity flagged so you can decide deliberately rather than by accident.
How to fix it
Create a web app manifest with related_applications and add a service worker. This enables the browser's native app install banner, which is not subject to Google's intrusive interstitial penalty.
Mobile best practices
- Ship a correct viewport meta tag on every page — it is one line and it gates everything.
- Keep tap targets ≥ 44×44px with real spacing between them.
- Never let content overflow the viewport horizontally.
- Test on a real mid-range phone over 4G, not just desktop devtools.
- Avoid intrusive interstitials — Google demotes pages that greet mobile users with a wall.
