Title Element and Title Meta - what is the difference?

[Errioxa]

Hello, What is the difference between this metas?

<title>My Title</title> and <meta name="title" content="My Title"></meta>

<meta name="description" content="My description"></meta> and <meta name="DC.Description" lang="por" content="My Description"./>

The one you don't want to forget is <title> as that is what appears in the browser bar, and the se's like to see that. The other two are taken by se's and sometimes used in serp results if so configured.

Forget about
<meta name="title" content="My Title"></meta>

Not only is the syntax incorrect (there is no closing tag with meta elements), but there actually is no such thing as a title meta tag.

People have been talking about a title meta tag, when they actually meant the <title> element. However, while in function the title element somewhat resembles a meta tag, it is not.

The DC meta tags are not used by search engines that matter. I would forget about these too.

The title meta does exist, or did exist, but no search engines index it. It was used for internal indexing, but never really caught on.
