## Introduction

**Image sitemaps** help search engines discover image URLs—especially on large catalogs, JavaScript-heavy pages, or when images are not well linked from HTML. A sitemap **does not** replace quality content, alt text, or fast delivery; it is a **crawl hint** layered on top of a solid page experience.

## Official guidance

Google’s [image sitemaps documentation](https://developers.google.com/search/docs/crawling-indexing/sitemaps/image-sitemaps) explains XML schema, optional fields, and limits. Keep sitemaps **fresh**: remove URLs that 404 and include canonical image locations when you have duplicates.

## What to include

* **Canonical page URL** where the image appears.
* **Image loc** with absolute HTTPS URLs.
* Optional **caption** and **title** where they add real value—avoid duplicate boilerplate across thousands of SKUs.

## Quality still matters

Sitemaps do not fix blurry thumbnails or keyword-stuffed alt text. Pair them with [product photo resolution](/blog/product-photos-correct-resolution-prevent-blur-on-retina) and meaningful alt text. Technical discovery without content quality rarely wins rankings.

## Performance and LCP

Indexed images should load fast in context—see [lazy loading and LCP](/blog/lazy-loading-lcp-priority-image-selection). After deploys, [CDN cache](/blog/cdn-cache-stale-images-after-update) can affect what users (and tests) actually see.

## Turkish parallel

[Görsel site haritası (Türkçe)](/blog/image-sitemap-gorsel-site-haritasi-seo) covers the same workflow.

## Conclusion

Combine image sitemaps with **fast pages**, **clear alt text**, and **stable URLs**. Discovery is step one; relevance and experience decide visibility in Google Images.
