What is an Image Sitemap?
An image sitemap is a special file that gives a search engine detailed information about the images on your website. While Google can crawl images on its own, an image sitemap makes the process easier by pointing directly to important image files and giving extra details.
This helps a search engine understand:
- Where your images are located
- What each image represents (with descriptive tags)
- How images connect to your content
In short, an image sitemap improves the visibility of your images in a search engine’s image search and enhances your overall SEO.
Why is an Image Sitemap Important?
Images are not just design elements they can drive a lot of organic traffic. With an image sitemap, you ensure:
- Better Discovery: Search engines can easily find your images, even if they’re loaded dynamically or hidden behind scripts.
- Image Search Visibility: Your images can appear in Google Images with proper context.
- Higher Page Value: Well-indexed images improve your chances of ranking in search results with rich snippets.
- Support for E-commerce & Blogs: For websites with product images or infographics, sitemaps ensure maximum exposure.
How to Create an Image Sitemap
There are two main ways to create an image sitemap.
1. Add Images to an Existing Sitemap
If you already have a sitemap for your website, you can include image information inside each <url> entry.
XML
<url> <loc>https://www.example.com/product-page</loc> <image:image> <image:loc>https://www.example.com/images/product1.jpg</image:loc> <image:caption>Luxury Wooden Bed Frame</image:caption> <image:title>Super King Wooden Bed</image:title> </image:image> </url>
2. Create a Separate Image Sitemap
If your site is image-heavy, you may prefer a dedicated image-sitemap.xml file.
3. Use Plugins or Tools
On platforms like WordPress, SEO plugins can generate image sitemaps automatically. A professional SEO platform like Clickrank can help with this. The platform can scan your website for these issues and give you a clear, prioritized list of what to fix.
Best Practices for Image Sitemaps
To make the most out of your image sitemap:
- Use descriptive titles and captions for each image.
- Ensure images are not blocked in
robots.txt. - Always use high-quality, compressed images for faster loading.
- Update the sitemap whenever new images are added.
- Submit your image sitemap in your search console for indexing.
How to Submit an Image Sitemap to Google

This ensures Google knows where to find your image sitemap and crawl it regularly.
