Keyword density control is a direct impact on the ranking of factors, then what is the density of keywords? keyword density is the ratio of the total number of times a keyword or a keyword appears on a page to other text.

The more keywords that are commonly found on the site, then the keyword density will be increased, in the optimization of the keyword Best control in 5%-8% that can be, a lot of SEO webmaster in order to get a better ranking, and constantly on the site to stack keywords, so that the entire site is full of key words traces, Rather than what is really needed, is it to rank? or to further highlight the subject? In fact, it is wrong, this will not only add an additional burden to search engines, but also to the rank of a point of no benefit, a long time, will also cause the search engine suspicion, the eventual face may be suspected of cheating by K. Like this site, in the optimization of one months have no rankings, and site home page in Baidu also disappeared, in the process of optimization, are also in accordance with the formal means, but just do not understand the problem where, and then after the comparison with the competition and their own experience of the summary, just know the keyword density is not controlled well, Now, after a slow adjustment, the effect has been significantly improved. In fact, this is an example, I believe that webmasters may have the same experience. So, to follow the search engine's "rules" to do, to try to be natural, smooth.

So how does a search engine measure the density of a keyword?

First of all, from participle. There is no natural separator between words or words, and words are usually made up of two or two of Chinese characters. Therefore, the search engine is according to some kind of algorithm to divide the content of the page body into several Chinese words. such as "Plate heat exchanger" The word, search engine will be cut into "plate"; HEAT EXCHANGER ", then the heat exchanger so the keyword density in the Web page is" 1/2 ". For the phrase keyword density, it is usually measured by the density of each word in the constituent phrase that the density of the phrase is reasonable. For example: "Mary Kay to create perfect women" cut into "Mary Kay", "Build", "perfect", "female." So the word "Mary Kay" appears once in this statement, the keyword density is "1/4".

How to see the site's keyword density is too high? The density of the site's keywords is generally expressed in the following areas:

One, the snapshot does not update

Second, the keyword ranking fell or not row up

Third, the collection gradually reduced

Four, site home disappear

If there are several cases, it is necessary to consider whether the keyword density is too high factor, so in the optimization of the time must control the density of good keywords, reasonable layout. To get a good ranking.
