Advantages of Image Optimization
Image Optimization is necessary as it helps to reduce the loading time of the site and also helps to utilize the available bandwidth. File size reduction helps us to achieve that. It is useful from Seo point of view as sites that load faster are considered better for the user by the searchengines. It also helps the search engine robots to identify the image with the help of the alt tags as the robots are unable to read the image.
