The website displayed a throbber while the page was loading.
Throbber → The word is formed from "throb" (from Old English *þrobbian*, meaning to beat or pulsate) and the suffix "-er" (meaning a person or thing that performs an action). A throbber is something that causes a throbbing sensation or a person who experiences or creates a throbbing effect.
Think of something that 'beats' or 'pulsates' ('throb') and remember that a 'throbber' is something that creates that throbbing sensation.
