Page insight : Effeciently Encode Image
❓ What does it mean?
❓ What does it mean?
“Efficiently Encode Images” is a Google PageSpeed Insights (PSI) recommendation that tells you your images are not properly compressed or optimized.
Unoptimized images can:
Be larger in file size than necessary.
Slow down page load times.
Negatively impact Core Web Vitals like LCP (Largest Contentful Paint).
🚨 Why is it important for SEO?
🚨 Why is it bad for SEO?
Slower Page Speed ⏳
Heavy images increase load time → poor user experience.
Lower Core Web Vitals Score 📉
Google uses Core Web Vitals as a ranking signal.
Higher Bounce Rate 👎
Visitors abandon slow-loading pages, reducing engagement.
Mobile Performance Issues 📱
Large images affect bandwidth-constrained mobile users the most.
✅ How to Fix It
✅ Best Practices
Use Next-Gen Formats → Convert images to WebP or AVIF.
Compress without quality loss → Use tools like TinyPNG, Squoosh, or ImageOptim.
Serve responsive images → Use srcset and sizes in HTML for different devices.
Lazy-load offscreen images → Load images only when visible (loading="lazy").
Use CDNs for images → Faster global delivery.
❌ Bad Example
📌 Example
❌ Bad (Unoptimized Image):
<img src="shoes-banner.jpg" alt="Shoes Banner" width="1200" height="600">
shoes-banner.jpg → 1.5 MB, JPEG, not compressed.
Slows down LCP and overall page speed.
✅ Good Example
✅ Good (Optimized Image):
<img
src="shoes-banner.webp"
alt="Shoes Banner"
width="1200"
height="600"
loading="lazy">
Converted to WebP → only 250 KB.
Added lazy loading for better performance.
