1.5 Performance & Core Web VitalsMediumInferred
Excessive page weight
A multi-megabyte page is slow on mobile and expensive on a metered connection. Weight is rarely one big thing; it is usually many unoptimised images, scripts and fonts adding up.
What it is
Multi-MB pages.
Why it matters
Slow loads, worse CWV, more crawl resource.
How to fix it
Compress, lazy-load, trim payloads.
How to find it on your site
- Open the DevTools Network tab and read the total transferred size.
- Sort by size to find the heaviest resources.
- Compress images, remove unused scripts and fonts, and split large bundles.
- Re-measure the total weight after trimming.
Cross-reference to ranking and citation factors
Lighter pages load faster, which supports Core Web Vitals and reduces bounce on mobile. Weight is a lever on nearly every speed metric.
Impact
