Why Is Image Optimization Critical?
Images make up a significant portion of most websites. Oversized or heavy images drastically slow down loading times, hurting both user experience and search rankings.
Choosing the Right Image Format
Formats like JPEG, PNG, WebP, and AVIF each have different advantages. Modern formats (WebP, AVIF) offer higher quality at smaller sizes. However, AVIF is not yet supported on all browsers, making WebP the safer choice.
Resizing and Compressing Images
Images should be optimized according to their placement. For example, using a 2000px wide image for a small icon is unnecessary. With both lossless and lossy compression methods, you can reduce size without visible quality loss.
Delivering Images with a CDN
Content Delivery Networks (CDNs) serve images from the closest server to the user, dramatically reducing loading times. This is especially valuable for websites with international audiences.
Conclusion
Image optimization is a cornerstone of improving your PageSpeed score. By using the right formats, compression techniques, and CDNs, you can enhance both SEO performance and user satisfaction.
