Keywords - words or phrases which that
specific page or content is based on. Typically keywords should not be
words, but be phrases. Targeting a specific key phrase will allow you
to list better and have more targeted traffic.
The most important place to place keywords is in the
page title and page copy. Most major search engines ignore the keywords
meta tag as many people were using it to spam. Also note that a single
entry of keywords is not enough to develop relevancy. The same keywords
must be listed in the copy multiple times in multiple locations to list
well in top search engines for competitive phrases.
