One of the key elements when optimizing our websites to improve search engine positioning is the images. In the HTML language, all the images must have the Alt attribute, which is translated into the alternate text of the image, this text will also appear on our website in case an error occurs when loading the image.
It is the same attribute that helps us “tell” the robots of Google that this image is treated, this way also the photos are indexed and helps us to position ourselves better in the results of Google.
Another advantage of the alt attribute is that if for some reason the server cannot load the image correctly, the browser will display the text it contains within the attribute.
