Meta Tags
What are meta tags? They are information inserted into the “head” area of your web pages. Other than the title tag (explained below), information in the head area of your web pages is not seen by those viewing your pages in browsers. Instead, meta information in this area is used to communicate information that a human visitor may not be concerned with. Meta tags, for example, can tell a browser what “character set” to use or whether a web page has self-rated itself in terms of adult content.
The Title Tag
The HTML title tag isn’t really a meta tag, but it’s worth discussing in relation to them. Whatever text you place in the title tag (between the <TITLE> and </TITLE> portions as shown in the example) will appear in the reverse bar of someone’s browser when they view the web page. Title tags are the first things, which search engines see.
