Understanding the Importance of Image SEO
Image SEO is the practice of optimizing images on your website to improve their visibility in search engine results. While Google’s algorithms are constantly evolving, the fundamental principles of image SEO remain crucial for driving organic traffic.
Enhanced User experience: Optimized images load faster, contributing to a better user experience, which is a ranking factor.
Increased Organic Traffic: Well-optimized images can rank in Google Images and contribute to overall website traffic.
