Also, consider enabling lazy loading.This technique loads images as soon as the user sees them, thus preventing the entire site from slowing down. To go even further, integrate structured data such as schema.org/ImageObject, especially for product or recipe images, so that Google can understand their precise context. On a practical level, you should also ensure that the display is responsive by correctly defining the width and height attributes. Using a CDN to deliver your visuals is another essential tip to guarantee optimal loading times, especially when your audience spans multiple regions. The speed of your site, and therefore the speed of your images, directly influences your ranking and user experience.
