In SEO Keyword density can be an indicator of the number of times the selected keyword appears within the web page. But mind you, keywords shouldn’t be over used, but ought to be just sufficient enough to appear at important places. It helps search Engine ranking.
When you repeat your keyword phrases with every other word on every line, in that case your site will probably be rejected as a possible artificial site or spam site.
Keyword density is always expressed as a percentage of the total word content on a given web site ranking on Search Engine Optimizing.
Suppose you have 100 words on your own webpage (not including HMTL code used in writing the internet page), and you make use of a certain keyword for half a dozen times in the content. The keyword density on that page is got simply by dividing the sum of the amount of keywords, by the amount of words that display on your web page. So now it is 5 divided by 100 = .05. Because keyword density is a percentage of the total word count on the page, multiply the aforementioned by 100, that is .05 x 100 = 5%
The accepted standard for a keyword density is between 3% and 5%, to get identified by the various search engines and you should never exceed it.
Remember, that this rule is applicable to every page on your own site. It also relates 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%.
Simple steps to check the density are as follows:
1. Copy and paste the content from an individual website page into a word-processing software program like Word or Word Perfect.
2. Go to the ‘Edit’ menu and click ‘Select All’. Now navigate to the ‘Tools’ menu and select ‘Word Count’. Write down the entire number of words within the page.
3. Now select the ‘Find’ function on the ‘Edit’ menu. Go to the ‘Replace’ tab and type in the keyword you would like to find. ‘Replace’ that word with the same word, so you don’t change the text.
4. When you complete the replace function, the system will provide a count of the words you replaced. That gives the number of times you have used the keyword in that page.
5. Using the total word count for the page and also the total number of keywords you can now calculate the keyword density.
