Images make up a large share of the content on most websites, yet they are often the most neglected part of an optimization plan. Many site owners upload photos straight from a camera or phone with filenames like IMG_4821.jpg or DSC00093.png and never think about them again. That is a missed opportunity. Search engines cannot see an image the way a person does, so they rely on text signals to understand it, and the filename is one of the first signals they read. Learning how to name photos for SEO is a simple habit that can improve image search visibility, strengthen page relevance, and make your media library far easier to manage.

Why Photo Filenames Matter for Search
Google has stated in its image publishing guidelines that filenames can give it clues about the subject matter of an image. A file named red-leather-office-chair.jpg tells a crawler far more than chair1.jpg or a random string of characters. While a filename alone will not push a page to the top of the results, it contributes to the overall context that search engines build around a page. When the filename, alt text, surrounding copy, caption, and page title all point to the same topic, the image has a much better chance of appearing in Google Images and in visual results within the main search page.
Descriptive filenames also help with accessibility and usability. When an image fails to load or is downloaded by a user, a clear name communicates what it is. Internally, content teams can find assets more quickly when files are named logically, which reduces duplicate uploads and keeps a media library organized.
Best Practices for Naming Photos for SEO
Follow these guidelines each time you prepare an image for upload:
- Describe the image accurately. Name the file after what the photo actually shows. If it is a golden retriever puppy playing in snow, say so: golden-retriever-puppy-playing-in-snow.jpg.
- Use hyphens to separate words. Google recommends hyphens rather than underscores or spaces. Spaces often turn into %20 in URLs, and underscores may join words together in the eyes of a crawler.
- Keep it lowercase. Some servers treat uppercase and lowercase characters as different files. Lowercase names prevent broken links and duplicate versions.
- Include a relevant keyword naturally. If the page targets a specific phrase, consider including it when it genuinely describes the image. Do not force it.
- Stay concise. Three to six meaningful words is usually enough. Long filenames stuffed with keywords look spammy and add no value.
- Avoid special characters. Stick to letters, numbers, and hyphens. Symbols such as ampersands, apostrophes, and accented characters can cause encoding problems.
Examples of Good and Bad Image Filenames
Seeing the difference side by side makes the principle clear. A bad filename might be IMG_20260914_103322.jpg, which carries no meaning. A slightly better but still weak filename might be product.jpg, which is too generic to differentiate. An over-optimized filename such as best-cheap-running-shoes-buy-running-shoes-online-running-shoes-sale.jpg reads like keyword stuffing. A strong filename would be womens-blue-trail-running-shoes.jpg, which is specific, descriptive, and naturally aligned with what a shopper might search for.
For location-based businesses, adding a place can be useful when it is relevant. A restaurant might use wood-fired-margherita-pizza-austin.jpg on a page about their Austin location. A real estate agency might use modern-kitchen-renovation-lakeview-home.jpg. The key is that the name still describes what is visible in the photo.
Pair Filenames With Strong Alt Text
Filenames and alt text work together, but they serve different purposes. The filename is a short label, while alt text is a sentence-like description used by screen readers and displayed if the image cannot load. Alt text should describe the image in context, such as "Woman lacing up blue trail running shoes on a rocky mountain path." Avoid copying the filename word for word into the alt attribute, and never leave alt text empty on meaningful images. Decorative images that add no information can use an empty alt attribute so screen readers skip them.
Other Image SEO Factors to Consider
Naming is only one piece of image optimization. To get the most value from your visuals, also pay attention to the following:
- File size and format. Compress images and use modern formats like WebP or AVIF where supported. Faster pages improve user experience and Core Web Vitals.
- Responsive images. Use srcset and sizes attributes so devices download an appropriately sized version.
- Surrounding content. Place images near relevant text. Search engines use nearby headings and paragraphs to interpret them.
- Structured data. Product, recipe, and article schema can make images eligible for rich results.
- Image sitemaps. Including images in your sitemap helps search engines discover files that might otherwise be missed, particularly those loaded with JavaScript.
How to Rename Existing Photos Without Hurting SEO
If your site already has hundreds of poorly named images, you do not need to rename everything at once. Start with your most important pages, such as top product categories, service pages, and high-traffic blog posts. When you rename a file that is already indexed, the URL changes, so set up a 301 redirect from the old image URL to the new one where possible, and update every reference in your content. Many content management systems offer plugins or built-in tools that handle this safely. Going forward, create a naming convention document so every team member uploads images consistently.
Conclusion
Knowing how to name photos for SEO is one of the easiest wins available in on-page optimization. Descriptive, lowercase, hyphen-separated filenames help search engines understand your visuals, improve accessibility, and keep your media organized. Combine good naming with thoughtful alt text, compression, and relevant surrounding content, and your images can become a steady source of additional traffic. If you would rather have experts handle it across your entire site, partnering with an experienced agency ensures that every image supports your wider visibility goals.
