These are the top ten reasons why you should use tagging in CQ5:

10. CQ5 is great when dealing with structured information thanks to the nesting of pages and paths. It is also great when dealing with unstructured information thanks to the built-in full-text search. Tagging allows you to combine the strengths of structure and flexibility.

9. Tags have many names and faces: tags, taxonomy terms, categories, labels and many more. They are flexible in their content model and flexible in the way they can be used, for instance for outlining target demographics, categorizing and rating content or to create a secondary content hierarchy.

8. Tags can be created by anyone who needs a quick way to annotate a page. This helps you with search-engine optimization, as tags will automatically show up in the meta-tags of the page, and ensure your page will be found by search engines.

7. Tags combine Web Content Management, Digital Asset Management and Social Collaboration. The tagging system is a core component of CQ5 and it is used by all CQ5 Applications to categorize content. Additionally it is available to developers for their own tagging-enabled applications.

6. Tags can be simple and sophisticated at the same time. To create a tag all you need is a word and the touch of a button. That's simple. But afterwards you can add a title and description to it to add more semantics. There are no limits on the labels you select for your tags.

5. Tags improve your search experience. You can search for tags and for content that has tags. This is used in CQ5's default search component, so your users can drill down to see only the results that matter in the search result pages.

4. Tags powerful organizators. With the ability to create tags and sub-tags it becomes possible to express whole taxonomic systems of terms and subterms and their relationships. This allows you to create a second (or third) content hierarchy next to the official one.

3. You can never have too many tags. And if you have, you can create namespaces to sort and organize your tags. With namespaces you can make sure that tags that belong together are together and create categories of tags.

2. Tags can be controlled. With all the flexibility and simplicity of tags, you have still full control over all your content. Apply permissions to tags or namespaces to control who can create or use your tags.

And the number one reason why you should use tagging in CQ5 is:

1. Tagging makes your life easier by giving you a better way to organize content without too much thought.
