For this reason, it is important that you design your site for all device types and sizes. Create device-friendly sites: Users search on Google Images more from mobile than on desktop.Page content may be used to generate a text snippet for the image, and Google considers the page content quality when ranking images. Create informative and high quality sites: Good content on your webpage is just as important as visual content for Google Images - it provides context and makes the result more actionable.To ensure maximum accessibility of your content, keep text in HTML, provide alt text for images. Don't embed important text inside images: Avoid embedding text in images, especially important text elements like page headings and menu items, because not all users can access them (and page translation tools won't work on images).When it makes sense, consider placing the most important image near the top of the page. Optimize placement: Whenever possible, place images near relevant text.We particularly discourage pages where neither the images or the text are original content. We suggest that you display images only where they add original value to the page. Provide good context: Make sure that your visual content is relevant to the topic of the page.To boost your content's visibility in Google Images, focus on the user by providing a great user experience: make pages primarily for users, not for search engines. You can also prevent the image from appearing in search results entirely. This behavior is not considered image cloaking and will not result in manual actions. This opt-out is possible at any time, and does not require re-processing of a website's images. Google will still crawl your page and see the image, but will display a thumbnail image generated at crawl time in search results. If the request is coming from a Google domain, reply with HTTP 200 or 204 and no content.When your image is requested, examine the HTTP referrer header in the request.If you choose, you can prevent the full-sized image from appearing in the Google Images search results page by opting out of inline linking in Google Images search results.
