Google extracts information nearly the subject thing of the image from the content of the page, including captions and image titles. Wherever possible, make sure images are placed near relevant text and on pages that are relevant to the image subject matter.

Besides, the filename can give Google clues about the subject matter of the image. For example, my-new-blackness-kitten.jpg is better than IMG00023.JPG. If you localize your images, brand sure yous translate the filenames, too.

Use descriptive alt text

Alt text (text that describes an paradigm) improves accessibility for people who tin can't meet images on web pages, including users who use screen readers or have low-bandwidth connections.

Google uses alt text forth with computer vision algorithms and the contents of the page to understand the subject affair of the image. Also, alt text in images is useful every bit anchor text if you decide to use an epitome every bit a link.

Use semantic markup for images

Google parses the HTML of your pages to alphabetize images, but does non alphabetize CSS images.

Good: <img src="puppy.jpg" alt="A gilt retriever puppy" />
Bad: <div style="groundwork-image:url(puppy.jpg)">A aureate retriever puppy</div>

Use an image sitemap

Images are an important source of information about the content on your site. You tin requite Google additional details about your images, and provide the URL of images we might not have otherwise discover by adding information to an prototype sitemap.

Image sitemaps can contain URLs from other domains, unlike regular sitemaps, which enforce cross-domain restrictions. This allows you to use CDNs (content delivery networks) to host images. We encourage you lot to verify the CDN's domain proper noun in Search Console then that we can inform you of whatever clamber errors that we may find.

Supported image formats

Google Images supports images in the post-obit formats: BMP, GIF, JPEG, PNG, WebP, and SVG.

You tin besides inline images every bit Data URIs. Information URIs provide a way to include a file, such as an prototype, inline by setting the src of an img element every bit a Base64 encoded string using the following format:

<img src="data:image/svg+xml;base64,[information]">

While inlining images tin reduce HTTP requests, carefully approximate when to use them since information technology can considerably increase the size of the page. For more on this, refer to the section on pros and cons of inlining images on our Web Fundamentals folio.

Responsive images

Designing responsive web pages leads to better user experience, since users use them beyond a plethora of device types. Refer to our Web Fundamentals on Images to learn almost the best practices for handling images on your website.

Webpages use <img srcset> attribute or <picture> chemical element to specify responsive images. However, some browsers and crawlers do non empathize these attributes. We recommend that you ever specify a fallback URL via the img src attribute.

The srcset attribute allows specifying different versions of the same prototype, specifically for different screen sizes.

Example: <img srcset>

<img srcset="case-320w.jpg 320w,        example-480w.jpg 480w,        example-800w.jpg 800w"    sizes="(max-width: 320px) 280px,       (max-width: 480px) 440px,       800px"    src="example-800w.jpg" alt="responsive spider web">

The <picture> element is a container that is used to group different <source> versions of the aforementioned epitome. It offers a fallback approach and so the browser can choose the correct image depending on device capabilities, similar pixel density and screen size. The picture element as well comes in handy for using new image formats with congenital-in svelte deposition for clients that may not yet support the new formats.

We recommend that you always provide an img element equally a fallback with a src attribute when using the picture tag using the post-obit format:

Example: <moving-picture show>

<film>  <source type="epitome/svg+xml" srcset="pyramid.svg">  <source type="image/webp" srcset="pyramid.webp">  <img src="pyramid.png" alt="large PNG image..."> </picture>
