Often engage in a lot of search engine optimization colleagues asked keyword problem.    For example: the number of pages a keyword or keyword phrase for a more favourable ranking or a page keyword density is more conducive to the number of issues such rankings.    Below on my personal experience for keywords, and talk about the relationship between the rankings. 

  From the industry, people prefer to use a page keyword density search engine rankings as a reference rather than a keyword or a page in the number of keyword phrases. 

  So what is the keyword density? A lot of people think that keyword density is that the keywords in Web content (companies) of the percentage is not the so-called keyword density should be referring to a page with keywords, in addition to html code swap the contents of the percentage.    Seems to be a rather abstract concept, with the following code share with you elaborate keyword density: 

  Keyword1 is keyword2, keyword3 is a beautiful glass! 

  From the above code, in addition to the HTML code, the remaining content is (from top to bottom): 

  "Keyword1, keyword2, keyword3" 

  "Keyword1, keyword2, keyword3" 

  "Keyword1 is keyword2" 

  "Keyword1 is keyword2, keyword3 is a beautiful glass!" 

  A total of 16 words, we have to calculate the following keyword1 keyword density, as in all the contents of keyword1 has emerged in the 4th, then we would take it that keyword1 keyword density is 4 / 16 = 25%; From this example we keyword density in the calculation of the time of the html code labels out of the pages of the list of contents. 

  End keyword density understand what is, we continue to explore the keyword density and the size of the relationship between the website ranking.    According to some professionals observation study shows that in the majority of the search engine keyword density in the 2% to 8% is a more appropriate range is conducive to the search engine site rankings. 

  Keyword density is the number one important factor, of course, can not be ignored, but the most important is the content.    Many people in order to reach 2% to 8% of the keyword density is not content quality, deliberately in the pages plus the goal of optimizing the key, but in fact do so sometimes it will be the opposite effect. 

  Doing site, the best is the original content, because if you combine the knowledge to write optimized content is the "best" content.    This decision in your overall level, the evaluation of an article content whether it is appropriate to consider from two aspects, the first article, Fluency, and the second is the keyword density.    It's a good article the keyword Position and not only does not affect the number of articles of fluency but also to "most" optimization requirements. 

  We optimized general is not a word but a phrase such as "search engine optimization," including the "search engines" and the "optimization" two words, not only to emphasize optimization, "search engine optimization" but also emphasized that "search engines" and "optimization."    A lot of people mistakenly think that he is the focus of "search engine optimization", so in the text constantly repeat that phrase.    (Note: you must remember optimized "search engine optimization" is a phrase rather than a word, if you optimize the "search engine", then you do not need to "search" and "engine" of separation), the search engine Recognition keyword phrase, the entire phrase will be split into a number of explanation and interpretation of the words. 

  I would like to the top of the section of this site should describe it is a good example of the optimization is "search engine optimization", "web site optimization" The two most important keyword phrases. 

  Summary: the location keyword not deliberately added to natural!
