Why some SERP results have one image and others have 3

Also there are different image configurations for the results with 3 images. Is that something I can control?

The number of images displayed in Search Engine Results Pages (SERP) is determined by Google’s algorithms and is not something you can directly control. The factors influencing this include the relevance and quality of the images, the website’s overall ranking, and the user’s search query.

For instance, a search query focusing on a specific product might trigger the display of three images representing different variations or aspects of that product. In contrast, a general search query like “dogs” might only show one image that best represents the overall concept.

The image configurations within a three-image result can vary based on Google’s assessment of which images are most informative and visually appealing for the specific search. This can include a combination of product images, infographics, and other visual representations relevant to the query.
