In this article, Iam going to tell you the main difference between keyword density, frequency, prominence and proximity, and how they affect search engine rankings and etc.

The density of keyword refers to the ratio (percentage) key words contained in all the number of indexable words in a Web page.

The ratio of density preferred of keyword varies Search Engine with the Search Engine. Generally I recommend to employ a ratio of density of keyword in the range of 2-8%.

You can like to use this tool for analysis in real-time of key word to help you to optimize ratio of Web page of a keyword density .

The keyword frequency refers to the number of times a keyword or the expression of key word appears in a Web page.

The theory is that more the stop watch one key word or expression of key word appears in a Web page, more than one Search Engine is to give the page for a research with these key words relevance.

Generally I recommend that you make sure that the key word or the expression of the most important key word is more often the key words of use in a Web page.

But made attention not maltreat the system by repeating the same key word or expressions of key word many and many times.
