What is a tag cloud?

A tag cloud (word cloud, or weighted list in visual design) is a visual representation for text data, typically used to depict keyword metadata (tags) on websites, or to visualize free form text.

 

Types of tag clouds

 

There are three main types of tag clouds:

  • those that use the frequency of occurrence of each word
  • those that use frequencies are aggregated over all items and user
  • those that use categorisation

 

Creating tag clouds

 

Most tag cloud generators allow you to load text from the URL or to type the text.

Users can often choose the colours, text direction, font, size and shape of the tag cloud.

Tag clouds can usually be shared via social media, saved onto the tagcloud generator website or saved as an image.
