Tags in wordpress are just another way to categorize the posts or pages. It tells the visitors what actually the post is about and helps the visitor to find the content very easily.
Now you would be thinking what is the need of tags when we already have categories. The answer is here : -
Although tags and categories works the same but there is a slight difference. Categories are the most general method of grouping content on a WordPress site. A category symbolizes a topic or a group of topics that are connected to one another in some way. Whereas you can think of Tags as keywords. The keywords which will give in-depth information about what is really inside a post.
For example if you have a personal blog where you write about your life experiences. You can add categories like: Society, Food, Free spirit, Travel, and movies. Now when you write a post about somewhere you had travelled, you will add it in the Travel category and You can add tags like Manchester, Heaven, Nature, Scenic, etc.
