Device Funnel Performance Gap
Expose where mobile, desktop, or tablet drop off relative to each other so fixes stay device-specific.
GA4 and Google Ads results for the most recent complete month 16/04/2026 - 15/05/2026. I compared sessions, add-to-carts, starts, and purchases to make the device gap clear.
Mobile needs the most attention because it brings the volume but loses the highest share before purchase. That is often a clear UX or speed issue, not a demand issue.
| Device | Sessions | Add to cart | Purchase | Read |
|---|---|---|---|---|
| Mobile | 19,840 | 1,560 | 620 | Volume, but leakier |
| Desktop | 12,430 | 1,440 | 840 | Cleaner conversion path |
| Tablet | 2,140 | 110 | 42 | Small sample |
Desktop is healthiest because it converts cleanly, which means it is capturing stronger intent. That makes it a useful benchmark for the weaker device journey.
Fix the mobile friction first, then protect the desktop path that is already working. I compared sessions, add-to-carts, starts, and purchases.
