New Best Practice Helps Large Sites Optimize Crawl Budget and Improve Efficiency
Google has recently updated its Image SEO best practices documentation, advising website owners and developers to use the same image URL when displaying the same image across multiple web pages. This small but impactful change aims to enhance crawl efficiency, especially for larger websites with heavy media usage.
The new update was officially added to Google’s help document on image SEO and was first reported by Barry Schwartz on May 12, 2025. Google specifically noted that websites should avoid using different file names or URLs for the same image if it appears on more than one page. Instead, the company recommends referencing the same image URL consistently throughout the site.
According to the update, “If an image is referenced on multiple pages within a larger website, consider the site’s overall crawl budget. In particular, consistently reference the image with the same URL, so that Google can cache and reuse the image without needing to request it multiple times.” This clarification is designed to help large websites avoid unnecessary duplicate crawls, allowing Google to cache images more efficiently.
Why This Matters
For many websites, especially those with extensive media libraries or ecommerce product catalogs, crawl budget can become an important consideration. A crawl budget refers to the number of pages and resources Googlebot will crawl on a site within a given timeframe. When websites use different image URLs for the same asset, it causes Googlebot to treat each instance as a separate resource. This leads to redundant crawling, consuming valuable crawl budget and potentially slowing down the indexing of more important content.
By standardizing the use of image URLs, developers can ensure that Googlebot recognizes and caches the image once, reducing server load and enhancing crawl efficiency. It also leads to better performance on the backend since fewer copies of the same image are stored on the server.
What You Should Do
If your site currently uses different image URLs for the same image on various pages, it may be time to perform a review. Work with your content management system or web development team to identify and consolidate duplicate images. Tools such as reverse image detection software can assist in locating repeated images across your domain and help you redirect them to a single, consistent URL.
Though this may not result in a massive crawl budget improvement for small sites, the cumulative effect on larger sites can be significant over time.
Conclusion
Google’s recommendation to consistently use the same image URL across different pages is a simple yet effective way to streamline crawling and improve SEO performance. By adopting this best practice, webmasters can save on crawl budget, improve server efficiency, and contribute to better indexing of their content. As always, staying aligned with Google’s evolving SEO guidelines is key to maintaining visibility and performance in search results.
