Meta Descriptions and Keywords.
Many search engines display the Meta description
as part of the results page. If a Meta description
is not provided, many search engines typically
display the first 50-70 words of a document.
Unfortunately, the header of a document might only
contain information about the author and hence it
would less likely be viewed. By providing a Meta description,
a search engine will more likely display a summary of the
document rather than simply the first few sentences.
Example of a Meta description.
Most search engines rank the information in the title of a
document higher than the information found in the
body of a document. Hence, it is important that a
descriptive title be provided for each document.
For example, if this document were placed on the Web,
either one of the following titles below would describe
this document. However, the longer title not only tells
the user exactly what to expect when this document is
viewed, but since it contains more keywords, it would
also more likely be retrieved and then viewed.
