Of course, the most basic and most important factor is that the search engine for the content of the direct matching word participle, and then according to the article The number of keywords and the frequency of preliminary judgments of the content of the article, recognition of the text, the density of keywords directly determines the content of the core theme of the article.

This is based on the principle that people will always repeat their interest in communication. In general, the greater the density of the keywords, the more concentrated the center of the site, the more vivid the theme. However, if more than a certain number, it may be the search engine as the optimization of excessive or even cheating and down the right. To give a clearer indication of the value of the keyword density, let's take the following sentence as an example.

Headhunters, hunting is an idea. Headhunters are not real headhunters.

The core word of this sentence is headhunting, which appeared 4 times altogether. The total appearing word has the hunting, the thought, for, is not, true, the Headhunter (4 times) Altogether 9 words, and so on the function word does not calculate. The density of the keywords is 4/9. This is a very large keyword density, but there is no doubt that the relevance of the main core word headhunting is very good. Search engines are also very easy to understand the meaning of this sentence.

Let's expand it.

The competition of modern society enterprise is more and more talented person's competition, the traditional enterprise's struggle channel, the price gradually becomes the puzzle thought, the collage culture such soft level. In the talent competition behind, "headhunting" has become a competition in the killer-level approach, can make the strength between the enemy in an instant reversal. The competition between talents has spawned the headhunting industry, and the rise of headhunting has aggravated the competition of talents.

Let's make a word for this passage.

Modern/social/enterprise/competition/The more/More/talent/competition/, traditional/enterprise/in the fight/channel/, spell/price/gradually/into/spell/thinking/, spell/culture/such/soft/level/. Behind/talent/competition//, "headhunting"/become/competition/the Killer/level/skill/, able/make/enemy/I////////////////////////////////////// Business/Talent/competition/The emergence of/headhunting/industry, while/headhunting/The rise/increase/aggravation/talent/competition/intensity/degree.

A total of 61 words appeared in the passage. Headhunting appeared 3 times, Talent appeared 4 times, Enterprises appeared 3 times, competition appeared 6 times, Spell appeared 4 times, followed by the relevant words have social, channel, price, market, thought, soft, level, birth, intensification, fierce, etc., through these words basically can judge this paragraph of the general meaning of the phrase is "enterprise competition, talent headhunting." But if you put it together with the previous sentence, the Headhunter appeared 7 times, and the subject is still a headhunter's relevance. The keyword density is 7/70, equal to 10%, because the correlation match, the search engine will be this paragraph of text index headhunting this keyword.

So how much is the keyword density appropriate? Generally 2%-8% is a normal range. But it's best to have the most density in the text. If the density of your core keywords is 1%, and an inadvertent word appears at a density of 2%, then the search engine may have misunderstood your center.

There is another question, some people will ask, such as headhunting industry, the keyword density of phrases is how to calculate it? The author believes that the so-called keyword density refers to only a single word or a proprietary word, and the density of the phrase can not be called keyword density, and search engines will also search the phrase for participle, And then start matching from the database.
