The notion of keyword density value predates all commercial search engines and the Internet and can hardly be considered an information retrieval concept. What is worse, keyword density plays no role on how commercial search engines process text, index documents, or assign weights to terms. Why then do many optimizers still believe in keyword density values? The answer is simple: misinformation.
Keyword Density Checker Tool can be used to determine keyword density of your website.
Keyword Density Example
If two documents, A1 and A2, consist of 1000 terms (l= 1000) and repeat a term 20 times (tf = 20), then a keyword density analyzer will tell you that for both documents Keyword Density (KD) KD = 20/1000 =
0.020 (or 2%) for that term. Identical values are obtained when tf = 10 and l = 500. Evidently, a keyword density analyzer does not establish which document is more relevant. A density analysis or keyword density
ratio tells us nothing about:
1.The relative distance between keywords in documents
(proximity)
2.Where in a document the terms occur (distribution)
3.The co-citation frequency between terms (cooccurance)
4.The main theme, topic, and sub-topics (on-topic issues)
The Conclusion:
Keyword density is separate from content, quality,
semantics, and relevancy.
