Total page weight exceeds 5MB: what it is, why it matters, and how to fix it

The total HTML transfer size exceeds 5MB, resulting in slow load times especially on mobile networks.

Large page payloads consume mobile data, drain battery, and take significantly longer to download on slower connections. Pages over 5MB can take 10+ seconds to load on 3G networks, leading to high bounce rates and poor Core Web Vitals scores.

Audit and reduce page weight by optimizing images (use WebP/AVIF, responsive images), minifying CSS/JS, removing unused code, implementing code splitting, and lazy-loading below-fold content.

This is a high-severity issue: it directly suppresses rankings or click-through on the pages it affects. It belongs in your current sprint, prioritised by how many pages carry it. It belongs to the performance family of checks.

Run a free Dr Urls audit: it crawls your site, detects total page weight exceeds 5mb on every affected page, shows example URLs, and generates a ready-to-use fix task. Re-scan after fixing to verify the issue is gone.
