First Contentful Paint First Contentful Paint — how long until the browser renders the first piece of content. Under 1.8s is good.
3.02 s
Largest Contentful Paint Largest Contentful Paint — how long until the largest visible element loads. Under 2.5s is good.
11.18 s
Total Blocking Time Total Blocking Time — total time the main thread was blocked, preventing user input. Under 200ms is good.
1.28 s
Cumulative Layout Shift Cumulative Layout Shift — measures visual stability. How much the page layout shifts during loading. Under 0.1 is good.
0.133
Speed Index Speed Index — how quickly content is visually displayed during load. Under 3.4s is good.
16.03 s

Page Load Progression
FPage Weight BudgetAction8.3 MB transferred, 340 requestsFIX
Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size.
Image bandwidth is high — modern formats (WebP/AVIF) and resizing typically cut it 50%+.

Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
JavaScript bundle is large — code-split routes and lazy-load off-screen components to defer.

Each request adds latency. Bundle small files, use sprites, or eliminate unnecessary requests.
High HTTP request count — bundling, sprite-ing, and HTTP/2 server push can reduce per-request overhead.

BResource Hints4 hints, 0 missing preconnectsREVIEW
Current Resource Hints
4 resource hints configured
Fonts are always fetched as crossorigin=anonymous; a preload without the attribute creates a different cache key, so the browser refetches when the actual font request happens. Sample: //heritageofficial.com.pk/cdn/fonts/assistant/assistant_n4.9120912a469cad1cc292572851508ca49d12e768.woff2, //heritageofficial.com.pk/cdn/fonts/assistant/assistant_n4.9120912a469cad1cc292572851508ca49d12e768.woff2. Add `crossorigin` (or `crossorigin="anonymous"`) to each preload.
Performance issues directly impact user engagement and conversion rates.
The same href shouldn't appear in multiple hint rels -- one wins, the others are wasted markup and may confuse cache behavior. Sample: //heritageofficial.com.pk/cdn/fonts/assistant/assistant_n4.9120912a469cad1cc292572851508ca49d12e768.woff2 (preload+preload).

84% of JavaScript execution time is spent on third-party scripts. Consider auditing which scripts are essential.
When third-party JS execution time exceeds your own, performance gains from frontend work are capped by code you don't own.
Learn more ▾ ▴
Every millisecond of third-party JS competes with your own for main-thread time. If their share is bigger than yours, optimization on your code base barely moves the needle. Audit, defer, or remove third-parties before further frontend optimization. Use Lighthouse's third-party audit to identify the worst offenders.
