Whether you run a website, a blog or an ecommerce store image optimization is something you want to learn because it will take you a long way down the line. Images can make or break your site if you do not optimize them properly for quality, size and meta data. I know that you got the image size and the speed part but you must be wondering what the hell is meta data? There is more to to image optimization than just using a jpeg compressor to reduce its size.
Well, the term “meta data” means data about data. So something which is said about the image is the meta data of the image.
Google now uses something called a blended search result. Blended search result is nothing but showing images and videos in its SERPs (Search Engine Result Pages).
