What is keyword density?
Keyword density, popular speaking refers to the number of keywords on the page, and the percentage of all the text on the page. The more times the keywords appear in the Web page, the higher the keyword density.
The effect of keyword density on rankings:
How do search engines judge the relevance of Web pages and user search keywords? Look at your keyword location, in addition to the title tag, keywords and description tags, anchor text and other places to appear in the keyword, of course, the page text content to appear in the keyword. If the keyword is not mentioned in the page, the page probably won't have much relevance to the keyword, is it?
But if the meaningless misuse of keywords on the page, it will be search engines as a keyword piling, so that the rankings of the page has a negative impact.
In fact, the effect of keyword density on rankings has now fallen to very small, and the relevance of the Web page does not depend solely on the page itself, but on the other large number of pages that you perceive-anchor text.
How much is the keyword density appropriate?
In keyword optimization, it is generally believed that the keyword density in 2%~8% is a more appropriate range. But the keyword density how many suitable and does not have the rigid explicit stipulation.
Seonile that there is no need to deliberately care about the keyword density of how much appropriate to talk about, the focus is on the content of the page in the theme and semantics to be related to the keyword, and no keywords must appear several times, not to add the keyword.
As long as you logically, according to the grammar of normal writing your Web page, according to the content needs, the natural occurrence of the keyword density high or low point, there is no relationship. Because search engines are just a common site visitors, as far as possible to provide the most valuable information to visitors is the most important, but also the true meaning of SEO.
