Embedding videos enhances engagement, but strains site speed. As a WordPress performance expert with 5+ years experience, I‘ll show you how lazy loading cuts load times.
What is Lazy Loading and Why it Matters
Lazy loading defers offscreen videos until users scroll near them. Instead of loading the full video, it swaps embeds with a thumbnail preview and play button.
According to Google research, the average page load drops by 65% when applying lazying loading across assets.
How it Works:
- User visits the page
- Page layout and content above the fold loads per usual
- When user scrolls toward an offscreen video, the JS listens for proximity
- At ~200px before entering viewport, it requests the full video embed
- Video loads just as user scrolls to it
Benefits:
- Faster initial page load speed
- Pages with videos [can take over 15 seconds](https:// Machmetrics.com/speed-blog/page-load-time-statistics/) to fully load. Lazy loading cuts this drastically.
- Reduced resource consumption
- Initial payloads cut by 30-60%, up to 1MB+ in savings
- Mobile data savings
- On average 50% savings for users
- SEO gains
- Pages with slower load times rank lower on SERPs. Lazy loading prevents this.

|Page Weight|4MB+|1-2MB|
|% Resources Loaded|100%|30-50%|
