Key words are the one of the most important factor in search
engine optimization(seo). SEO rank can be improved using
keywords and key phrases in the content of articles and Meta
Tags. Your article should be peppered in keywords and
phrases. The most important thing to remember using
keywords is not to over use the keywords so that the content of
the article is hard to read. Computers and humans read the
content and you must write for both to improve your SEO
website rank.
