TECHNICALLY, I need to know what are tags. I mean, those keywords that i use often to get a good search engine position. My posts always get ranked by tags and not by permalinks.
Let's suppose i'm not using WordPress and i want to create from scratch those tags. Are just links in a sitemap.xml pointing to a permalink?
I repeat, technically, what are tags?
Thanks for your help. =)

Each of those tags is usually a web link leading to an index page listing
all of the posts associated with that tag.
Only a Weblink? How does it work?
Thanks for ur help Mac. But still have no answer. The link you posted os theory. I need to know technically how tags are made. In the core of WordPress. The backend, the code. =)
Code wise, tags are exactly the same as categories. If you look at your WP database, you'll see both your categories and tags all together. They're made by defining a tag, which creates an entry on your database.
That's it.
As for why Google ranks your tags above your cats, I have no idea.
