Tags
Adding tags to an article, product, property or any other items, helps organize these items that have some similarities or are related in some way or another. On your website, when you click on a tag, it will take you to a "search page" with a list of all items matching this tag. Tags are separated by use of comma. In other words, you can write a single word, or a short phrase. While you are typing in a new tag, suggestions of existing tags will show up in the list.
You are recommended to use existing tags rather than making new tags with the same meaning.
Tags are very good for search engine optimization - SEO, as they are internally linking items of similar features/content together
