On a website using the modern theme, Website › Site Settings › Item Pages lets you decide what your search results, your gallery tiles and the item page itself show, and in what order. Drag the price up beside the title, switch off the share links, set how many words of the description appear in a listing, and choose which buttons show.

More fields adds any field you keep on your items, either as a line of its own or inside the description, with your own name in front of it. Preview the change on your own site before you save; nothing moves until you do. If your site uses a template of its own for these pages, the page tells you so.
