Best Practices for SEO-Friendly Image File Names

Search engines use image file names as a ranking signal. By renaming files properly, you can boost image SEO and improve your chances of appearing in Google Image Search.

1. Use descriptive keywords

Instead of IMG_1234.png, use blue-running-shoes.png.

2. Avoid spaces and special characters

Always use dashes or underscores. Spaces can break URLs and reduce SEO performance.

3. Keep it short and relevant

Long, confusing filenames don’t help. Stick to 2–6 words that describe the image.

4. Match with alt text

For the best results, align file names with image alt attributes in your HTML.
