There are a number of programs that search the World Wide Web for
documents and compile them into indexes. Some of these merely extract
filenames or titles from headers. Others use a more sophisticated method that
depends on you, the HTML author to include indexing information in the HTML
file in a specific format. This indexing information is called meta
information and can also be used to create your own local searchable indexes
of your Web pages.
The placement of these tags
is important. They should go in between the
<head> and
</head> tags in your html page.
Most search engines
will in the absence of META tags, use the textual contents to index your
document. This can be a hit and miss proposition. Some search engines won't
use the tags at all. These search engines rely on plucking
words from the text of your page.
(Especially text in <title></title> tags )
You can also create your <META> tags on-line, by using my friendly

<meta |
| http-equiv |
The HTTP-EQUIV attribute is the name of a
http header property. The HTML spec does not really define any fixed list
of properties that must be supported , and it is up to the viewing
agent to pick and choose what information to respond to.
The difference between HTTP-EQUIV and the NAME attribute
is that HTTP-EQUIV entries are represenative of http headers, whereas
the NAME arribute is more reflective of a property associated with the
page.

| content |
The CONTENT attribute
specifies a string value to associate as the content/value of the
property mentioned in (NAME or HTTP-EQUIV) attribute.

The remainder of the attributes are used far less often , and in most
cases you won't need them. |
| scheam |
The SCHEAM attribute
specifies a scheme or mechanism for interpreting or processing the
value referenced by the CONTENT attribute.
