Keyword density is an important concept for website owners to 
understand. Keyword density, in today's Internet, is what will 
ultimately improve your search engine optimization (SEO) ranking. 
The importance of having a high SEO rating is absolutely critical 
if you wish to have high volumes of traffic to your website. 

Let's talk first about SEO and what it does. If you type a search 
into google, yahoo, MSN, or any other major search engine there 
are likely to be thousands to hundreds of thousands of results 
come up on the search engine. So let us imagine that you sell 
ceramic dolls on your website. Now someone types "ceramic dolls" 
into a search engine, where in those thousands of website results 
does your website fall? Does your website rank on the first page? 
If you are like most websites, your ranking is probably somewhere 
in the depths of the results ranking well over number 1,000. 
Imagine a customer seeking what you sell, but not being able to 
find your business. Do you really think that someone is going to 
sift through the first 1,000 results to find yours?

Search engine optimization (SEO) simply means that you are going 
to employ methods that will move your website up in the search 
engines results for "ceramic dolls" or your own personal 
keywords. Research and common sense tells us that if a potential 
website visitor/customer does not find your website within the 
first 20 results, he or she will move on and try a new search or 
simply use one of the first 20 websites that he or she has found. 
This is where keyword density comes into play. 

In years past I can remember finding web pages that had hundreds 
of words listed at the bottom of the page, this was a common 
practice. The reason for this was so that the search engines 
would place this website on the results page if a web surfer 
typed in any of those hundreds of words. Times have changed and 
so have search engines. Today the search engines are much more 
sophisticated in how they locate websites to list in their 
results. 

Keyword articles (adhering to certain keyword densities) 
dramatically improve a websites SEO ranking. Going back to our 
ceramic dolls example, this site would want a keyword article 
written with the keywords "ceramic dolls" inside the article. 
This way when a web surfer types in "ceramic dolls," the site 
will come up much higher in the Search Engine Result Pages 
(SERP's). 

The search engines use certain algorithms that "read" these 
keywords for the surfer. If you go and type in any phrase into a 
search engine you will notice that the results show those 
keywords highlighted in bold. They show you how the keywords are 
listed in those web pages. Placing articles on your website that 
contain the keywords your customers are looking for will help 
your search engine ranking for these specific keywords. 

Now, you cannot simply type the "ceramic dolls" over and over 
again on the same web page. With the sophistication of today's 
search engines, doing that would actually harm your search engine 
ranking. You need to provide articles that not only contain the 
keywords, but articles that also contain some relevant 
information as well. 

There is great debate over what density to use in a keyword 
article. Suppose you want a 500-word article written on ceramic 
dolls. What percentage of the time (density) should the phrase 
"ceramic dolls" be used? Should it be in there 4% (20 times) of 
the time, 7%, or 12%? You must be careful because using the 
keywords too often hurts your rankings, while using too little 
doesn't improve your ranking enough. So what is the answer? The 
answer is that only those that develop the algorithms for the 
search engine companies actually know.........and they aren't 
talking. Most people use anywhere from 3%- 15% keyword densities. 
Some people believe that having the keyword phrase in the title 
and as the first word of every paragraph helps. Some believe that 
using "dolls that are ceramic" 18 times and "ceramic dolls" 2 
times in a 500-word article with 4% density will work. 

Here is what everyone does know, if you are not utilizing keyword 
rich articles on your website (regardless of the density you 
choose) you will not be very highly ranked in any of the search 
engines. Keyword rich articles are one of the best ways to 
advertise your site. If you want more visitors to your website, 
who translate into more customers, you must utilize keyword 
articles to improve your search engine rankings so that people 
can find your website.
