Tags help to categorize Community content and make it easier to find. For example, if 15 users tag their content with “Data Integration” then all 15 pieces of content can be viewed simply by clicking the “Data Integration” tag. The same tags are available throughout Community, and so you’ll see all content with that tag across all sections of Community.
When creating content, you have the option to add as many tags as you’d like to help other members find it. Simply select from the “popular tags” option or start typing the relevant keywords to see which tags are available.
