How much is the keyword density? This question is often asked by students, usually the answer is 2%-10%, but Shanhan today's article is not to tell you how much the best density, but to correct a wrong idea. Of course, I am not saying that some of the previous SEO predecessors put forward the answer is completely wrong, perhaps they are the original intention is correct, and the back was passed down when the misunderstanding. Why should I say this, because we all think that keyword density is the search engine to determine the relevance of the current page of the important reference factors, this is not wrong, the focus is to misunderstand the meaning of the keyword density.

What is the keyword density

First of all, we have to understand this meaning, keyword density refers to the current page in the number of keywords and other total text ratio, also known as "keyword frequency." Generally speaking, the higher the keyword density, the higher the relevance of the page, so the ranking is also higher, of course, the frequency of the keyword here is to take the nature as a prerequisite, otherwise it will bring punishment.

Second, the correct understanding of keyword frequency

Shanhan that the use of keyword frequency to express the more appropriate, understanding is clearer. Here we have a general understanding of the Search Engine crawl Web page process, which I have mentioned in the text of the Web page signal-to-noise ratio, we can also go to see. Search engine crawl to the page will be preprocessed, the process will be the page analysis, remove the code, and then extract the text content, which will use the word segmentation technology, the content extracted into a combination of a word and then stored in the index library.

Here to pay attention to the focus is "participle", understand the Chinese word after Baidu can clearly know this misunderstanding, do you think the usual word density will exist? for example, the key words of our article is: "keyword density how much good", to the index library has become "keywords/density/How much/good" This phrase, if this article does not appear in this complete phrase, then use the tool query is the density of 0, but in fact, as long as your page appears in the word after the word, and frequency is higher to achieve the effect.

In fact, we are doing keyword research will often use the principle of this participle, but many people still do not know with the entire site linked. Hope that we do not dwell on the problem of keyword density, as long as the control of the word after the word frequency can be (remember the above I said the nature as a prerequisite), I am in the "How To learn SEO" also mentioned in the article, I suggest that we learn more about the principle of search engine.
