How Google Identifies and Indexes Images
So what exactly does Google look at when indexing images? Let’s check out a quick overview before we explain how to optimize your images.
First, it checks out image type. The image types Google can index include BMP, GIF, JPEG, PNG, WebP, and SVG. To learn more about a particular image when Google’s algorithms index an image, Google looks at the written copy on the page where the image was found as well as the page’s title and body. Google also considers anchor text pointing to the image, the image’s filename, and its alt text. In addition, Google may use other methods like computer vision (methods for acquiring, processing, analyzing, and understanding images) and the caption from the Image Sitemap (a Sitemap incorporating image-specific tags, which we’ll elaborate on later in this post), if available, to learn more about the images it finds. – A Marketer’s Guide to Optimizing Images for Google Search by Pamela Vaughan
