You knocked out the easy desktop-only wins (blocking JS = 0 ms) but the main mobile bottlenecks—huge hero image + unused CSS + layout shift—are still there, and mobile PageSpeed actually worsened (66 → 61). Until those three issues are fixed you’ll stay orange on mobile.
What actually changed
| Metric | “Before”* | “After” | Δ | Comment |
|---|---|---|---|---|
| TBT (desktop) | ~140 ms | 0 ms | ▲ | They deferred / delayed Elementor & WP-core JS—good job. |
| LCP (desktop) | 1.3 s | 1.1 s | ▲ | Minor; hero still loads as CSS background, so improvement is just from JS deferral. |
| LCP (mobile) | 5.4 s | 5.2 s | ▲ | Practically unchanged—image still 500 kB+, still lazy-loaded. |
| CLS (mobile) | 0.24 | 0.23 | — | Layout still shifts because hero has no explicit dimensions. |
| Payload | 3.8 MB | 3.3 MB | ▼ 0.5 MB | They compressed some images but hero + fonts untouched. |

Why mobile is still slow
-
Hero image is still the LCP offender. It’s a 2,000-px JPEG served as a CSS background, requested after the CSS arrives. On a throttled 4G connection that alone adds ~2 s to LCP. Best-practice hero size is ≤1600 × 900 px & <150 kB WebP served as
<img>so the browser discovers it instantly Medium. -
~95 kB of unused CSS is still shipped on every visit. Lighthouse flags it; WP Rocket’s “Remove unused CSS” option is still disabled WP Rocket.
-
CLS is above the 0.10 target because the hero image and a few thumbnails are missing
width/height(oraspect-ratio) attributes; the browser can’t reserve space, so the content jumps when the images finally load web.dev.
