Understanding Image SEO and Its Importance
Image SEO is about more than just adding images to your website. It's a comprehensive strategy to ensure your images are discovered, indexed, and ranked well in Google Image Search. High-ranking images can drive valuable organic traffic to your website, improve user engagement, and contribute to your overall SEO efforts. Ignoring image SEO is a missed opportunity to enhance your online visibility.

Creating an Image Sitemap and Using a CDN
An image sitemap helps search engines discover and index all the images on your website. Submit your image sitemap to Google Search Console to ensure your images are properly crawled and indexed. Consider using a Content Delivery Network (CDN) to serve your images. A CDN distributes your images across multiple servers, reducing latency and improving website loading speed for users around the world.
Mobile Optimization and Responsive Images
Ensure your images are mobile-friendly by using responsive images. Responsive images automatically adjust their size based on the user's device, providing an optimal viewing experience on all screens. Use the srcset attribute in the
