Product Image SEO
Product Image SEO is the practice of optimizing product photos and graphics to improve visibility in Google Image Search and to support overall page ranking signals. Key optimizations include using descriptive, keyword-rich file names (e.g., red-running-shoes-nike-airmax.webp), writing informative alt text that describes the image accurately, and serving images in next-generation formats like WebP.
Additional best practices include compressing images to minimize page weight for Core Web Vitals, implementing responsive images with srcset for different screen sizes, and adding structured data to ensure product images are eligible for rich results in Google Images. Multiple high-quality images from different angles also reduce return rates and improve user confidence.
Why it matters for SEO
Google Image Search drives meaningful e-commerce traffic that is often overlooked. Properly optimized product images rank in image search and contribute to page-level signals. Image optimization also directly improves Largest Contentful Paint scores, making it a dual win for both SEO visibility and Core Web Vitals.
