Image Sitemap
Checks for the presence of an image sitemap to improve image indexing.
What is this check?
An image sitemap is a specific type of XML sitemap created to give search engines more information about the images on your site. This helps Google find and index all your important visual content.
Why is it important?
An image sitemap is crucial for any site where images are important (like eCommerce, portfolios, or blogs). It improves image indexing, boosts your chances of appearing in Google Image search, and allows you to provide extra context like captions and titles.
What is the impact?
Without an image sitemap, Google might not discover all your images, especially those loaded by JavaScript. This is a missed opportunity for significant traffic from image search.
Example Implementation
You can declare an image sitemap in your robots.txt file, similar to a regular sitemap:
Sitemap: https://www.yourdomain.com/image-sitemap.xml
