  3. Review total page size and individual resource sizes.
  4. Identify the heaviest resources — usually images and JavaScript.
  5. Target under 1MB total for good performance on mobile.

Frequently asked questions

What is a good page size?
Under 1MB is good, under 500KB is excellent. The average web page is 2-3MB which is too heavy. Mobile users on slow connections suffer the most from bloated pages.
What makes pages heavy?
Images are usually the biggest culprit (60-70% of page weight). Unminified JavaScript, web fonts, and third-party scripts add up. Use WebP images, compress assets, and lazy-load below-the-fold content.
Does page size affect SEO?
Indirectly yes. Larger pages load slower, which hurts Core Web Vitals scores. Google prioritizes fast-loading pages, especially on mobile-first indexing.
How do I reduce page size?
Compress images (WebP/AVIF), minify CSS/JS, enable gzip/brotli, remove unused code, lazy-load images, and limit third-party scripts. A CDN helps deliver assets faster too.
