When optimizing your site for SEO purposes there are several considerations to take into account. One that is often overlooked is the importance of optimizing the naming conventions of your site’s images.
Here is a guide how to achieve this.
Folder Structure for Images
If your site relies heavily on images for content, it is a great idea to prep your site with a rich folder structure. For example, if your site is about macro pictures of flowers. You could create folders that are named after each type of flower (e.g. roses) and subfolders within that folder that are named after the subtypes of that flower (e.g. red roses).
Name of Image
An important consideration when naming your image files is that it is better to name them name-of-image.png than name_of_image.png. By naming your image name-of-image.png, it will rank for name, of, image and name of image. If you were to go with the second option, Google will only rank it for name of image.
Don’t forget to add information to the alternate text and title fields. A good practice is to relate the content of those fields to that of the article in which they are contained within.

Once your site has appropriate image structure set in place, your site may receive a SEO boost from your optimized images.
