The Impact of Image Optimization on Website SEO
The art of image compression for Google-friendly websites
Website loading speed is core to 'Core Web Vitals', which directly affects Google search rankings. Among them, images are the largest factor, accounting for more than 60% of total page size. How can we reduce size while maintaining quality?
1. WebP and AVIF: Importance of Next-Gen Formats
Old JPEG or PNG has limits in compression efficiency. Using WebP can result in about 30% smaller sizes than JPEG for the same quality. Google search bots favor sites using modern formats.
2. Lossless vs Lossy: Finding the Perfect Balance
Not all images need to be kept at maximum quality. On the web, a quality setting of 80-90% can reduce size by more than half while being nearly indistinguishable to the naked eye. UltraUtils tools automatically find this 'sweet spot'.
3. Optimizing ALT Tags and Filenames
As important as compression is conveying content meaning to search bots. Use filenames with keywords like 'youtube-thumbnail-strategy.webp' instead of 'IMG_1234.jpg', and write descriptive ALT tags.
Performance Results
Image optimization is not just about reducing size; it is a powerful marketing tool that improves User Experience (UX) and boosts search rankings.
