What is Keyword Density?

1. Keyword density refers to the ratio (percentage) of keywords contained within the total number of indexable words within a web page.
2. The preferred keyword density ratio varies from search engine to search engine.
3. In general, it is recommended using a keyword density ratio in the range of 3-7%.
4. Keyword Frequency refers to the number of times a keyword or keyword phrase appears within a web page.
5. The theory is that the more times a keyword or keyword phrase appears within a web page, the more relevance a search engine is likely to give the page for a search using those keywords.

Keyword prominence.

Keyword prominence refers to how prominent keywords are within a web page. The general recommendation is to place important keywords at, or near, the start of a web page, sentence, title or meta tag.

Keyword proximity.

Keyword proximity refers to the closeness between two or more keywords. Usually, the closer the keywords are the better.

For example:

1. How Keyword Density Affects Search Engine Rankings
2. How Keyword Density Affects Rankings In Search Engine

Using the example above, if someone searched for "search engine rankings," a web page containing the first sentence is more likely to rank higher than the second. The reason is because the keywords are placed closer together. This is assuming that everything else is equal, of course.

Keywords in the web page text

1. Include at least 100 keywords in page text.
2. Use keywords at the beginning of the page.
3. Place keywords close to each other.
4. Repeat keywords 3-7 times for every 100 words. Here's an example of how it's measured. Let's assume the keyword phrase is "puppy food." Puppy food is our primary business. Since "is", "our," and other stop words are usually not counted, there are three "words" in the sentence: "puppy food," "primary," and "business." "Puppy food" makes 1/3 of the sentence, or 33%. Keyword density is almost never this high. The recommended density is 3-7%.
