One day, I went back-end blog administrator to analyze the visitors filtered the search words in DeafJoke.TV website. I looked few visitors are trying to find the keyword search word, oral through DeafJoke.TV internal search engine powered by WordPress. The search result for oral is Zero. None.
As I aware there are few video clips identify as oral, and the text-based does not have the word, oral in DeafJoke.TV archives. The search engine cannot filter the video clip format and image format to identify what are in there. How can I solve this to know what's video / image is in there from search engine?
The short, sweet and one word answer: Tag. The not-so-long answer: From wikipedia definition of Tag:
A tag is a (relevant) keyword or term associated with or assigned to a piece of information (like picture, article, or video clip), thus describing the item and enabling keyword-based classification of information it is applied to.
What does tag looks like in my very entry here? I applied this on my personal idea: web, technology, search, metadata, definition.
Where can I find tag[s] in my blog? There are multiple ways you could self-service to find: internal blog search field box or in my tag cloud page - displayed all of tags in alphabetical order, setting popularity in order by using smaller font size to larger font size. Take a look an idea from most popular tag-clouds sites:
I built my first tagging system inside my personal blog, generated by Movable Type blog management system. However, Wordpress (WP) does not include the tagging system but they offers a WP plug-in, Ultimate Tag Warrior, it need to get this plug-in installed manually.
The most popular blog web tools, Blogger, also support tagging. What about Xanga? Yes, they uses 'label' which are same meaning as tag. Take a compare the inputting the tags in blog application page (new entry / post):

Blogger

Movable Type

WordPress
Xanga
Conclusion: After setting up Ultimate Tag Warrior plug-in in WordPress for DeafJoke.TV blog site, then oral can be found in search results.
Tags come handy in search engine. It is not necessary to have tags in your blog, but it is more useful if you post vlog or pictures in your blog site. If you build tags, they will come.
