Keyword density is always expressed as the percentage of the total word content divided by your particular keyword. Say you have one hundred words and out of those words your keyword shows up seven times. This means that you keyword density is seven percent, which is the highest percent to strive for. Remember that this applies to every page on your website. So you should put your keywords in all your website's pages. It is also a good idea to have multiple keywords so you have more chances of getting people to your site. Ten keywords would probably be the highest that you should go since you will need to focus a considerable amount of attention to the keywords you have chosen.

There are many ways to check the keyword density of your websites. One way is to copy all your content and past it in word and check the total number of words and divide it by your keyword. You also can try some programs that calculate keyword density as well.

Keyword density is not the only thing you should do to achieve high search engine rankings, but it is an important step. Without keywords you would have very few visitors from search engines since you haven't told the search engines what your site is about. Pick out a few keywords, write content with at least three percent of your keywords and then repeat the process over and over. Soon, you will find that your website will appear on the first page search engines for that particular keyword you targeted. Keywords are a great way to achieve high search engine rankings.
