I have noticed that google has started to show little images next to search results on mobile devices. The first photo I have displayed on my website is my logo. Currently this is the image that is being displayed. It doesn't look good. My logo isn't square so it crops it and looks bad.
I am assuming that there is some sort of meta tag, just like the meta tag I used to tell Facebook what photo to display.
What do I put in my HTML to tell google what photo I want displayed there?
