image pack
Also called: image results, image block, images serp feature, image thumbnail
An image pack is a cluster of image thumbnails Google embeds inside a normal web search results page, usually as a horizontal row or grid, pulled from images on already-indexed pages. Tapping one opens Google Images and can send the visitor to the page hosting that image.
Google does not offer an “image pack” upload. The block is assembled automatically from images already embedded on indexed pages, so eligibility is an SEO outcome, not a submission.
Where it comes from and how to earn it
In Google’s own docs the components are named differently than the tracker-tool label. An image result is “a result that’s based on an image that’s embedded on a web page,” and it is “more likely to appear for image-seeking queries.” The thumbnail beside a blue link is the “text result image,” the most relevant image from that page for the query.
To be eligible, Google has to find and understand the image. Use standard HTML <img> elements (CSS background images are not indexed), keep one stable URL per image, and place the picture near the text it illustrates, because Google “extracts information about the subject matter of the image from the content of the page, including captions and image titles.” Descriptive filenames and alt text carry the topic. Sharp, high-quality photos win clicks, since “sharp images are more appealing to users in the result thumbnail.” Structured data can add a badge in Google Images.
Image packs skew visual and mobile: recipes, products, how-to steps, people, places, design. When a query returns one, the plain links get pushed down, so those thumbnails become prime real estate.
How it affects your traffic
When an image pack owns the top of a SERP you care about, ranking first in the classic links can still bleed clicks to whoever supplies the thumbnails. An audit of which target queries trigger image packs, plus fixing the crawlable-image, alt-text, and image-placement basics, is exactly the kind of overlooked win an SEO consulting engagement is built to catch. We map the SERP features on your money keywords, then prioritize the ones where a small on-page change flips a gray tracker icon to blue.
