Optimize Filename, “Alt” and Other Image Attributes
Image-related information can be provided for by using the “alt” attribute
Images may seem like a straightforward component of your site, but you can optimize your use of them. All images can have a distinct file name and “alt” attribute, both of which you should take advantage of. The “alt” attribute allows you to specify alternative text for the image if it cannot be displayed for some reason.
Why use this attribute? If a user is viewing your site on a browser that doesn’t support images, or is using alternative technologies, such as a [tippy title=”screen reader” reference=”” header=”on”]Software for speaking on-screen information or outputting to a Braille display.[/tippy], the contents of the alt attribute provide information about the picture.

Another reason is that if you’re using an image as a link, the alt text for that image will be treated similarly to the anchor text of a text link. However, we don’t recommend using too many images for links in your site’s navigation when text links could serve the same purpose. Lastly, optimizing your image file names and alt text makes it easier for image search projects like Google Image Search to better understand your images.
Store files in specialized directories and manage them using common file formats
Instead of having image files spread out in numerous directories and sub-directories across your domain, consider consolidating your images into a single directory (e.g. brandonsbaseballcards.com/images/). This simplifies the path to your images.
Use commonly supported file types – Most browsers support JPEG, GIF, PNG, and BMP image formats. It’s also a good idea to have the extension of your file name match with the file type.

Like other types of page optimization, file names and alt text (for [tippy title=”ASCII languages” reference=”” header=”on”]Abbreviation for American Standard Code for Information Exchange. A character encoding centered on the English alphabet.[/tippy] are most effective when they’re short and descriptive. Avoid using generic names like “image5.jpg”, “photo.jpg” or “004.gif”. If your site has thousands of images, consider using a program to automate the naming of images. Avoid lengthy, full sentence file names or stuffing keywords into the alt text. For users that cannot see images because of their settings or device used to access the page the alt text is important to provide an alternate way to convey information.

If you use an image as a link it is particularly important to fill in the alt text; it is like provide anchor text for a text link and it should help Google understand more about the page you are linking to. Note that this differs somewhat from the original reason for the alt text, which is to provide alternate info to users that cannot see the image. Avoid writing long, spammy text. Do not use only image links for your site’s navigation.
