Alt text (also called an alt tag or image tag) is assigned to images just in case the image itself does not load. A picture of a dog running may have an alt tag of “running dog” or “dog running through field”. Using alt tags solely for search engine optimization purposes is generally discouraged. A picture of a lawyer could have an alt tag of “lawyer, John Smith”, but an alt tag of “personal injury and wrongful death accident lawyer John Smith” could be considered keyword spam.
