Keyword
density is an indicator of the number of times the selected keyword appears in
the web page.
Keyword density is always expressed as a
percentage of the total word content on a given web page.
Suppose you have 100 words on your webpage
(not including HMTL code used for writing the web page), and you use a certain
keyword for five times in the content. The keyword density on that page is got
by simply dividing the total number of keywords, by the total number of words
that appear on your web page. So here it is 5 divided by 100 = .05. Because
keyword density is a percentage of the total word count on the page, multiply
the above by 100, that is 0.05 x 100 = 5%
The accepted standard for a keyword
density is between 3% and 5%, to get recognized by the search engines and you
should never exceed it.
Remember, that this rule applies to every
page on your site. It also applies to not just to one keyword but also a set of
keywords that relates to a different product or service. The keyword density
should always be between 3% and 5%.
