Keyword density of seo nouns

Keyword density, popular is a page, the keyword accounted for the total number of pages in the percentage of the page, here, I first quote Baidu Encyclopedia of Keyword density definition bar: keyword density (keyworddensity) is a keyword or a keyword in the page on the total amount of time and the proportion of other text. Relative to the total number of words in the page, the keyword appears more often, then the overall keyword density is greater. The more times the other text appears, the lower the number of keywords, and the smaller the keyword density. In today's article, and SEO colleagues to exchange some questions about SEO terminology, these several problems in the current SEO industry is still very vague. Little head bidding assistant to give you a detailed explanation today. &http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Problem one: keyword density of the computing ontology   above definition, we see: keyword density is a keyword in the total number of pages on the page, then from this literal understanding, the calculation of keyword density of the ontology is a Web page, in fact, we often do not consider a Web page in the work, But consider only one article in the webpage, that is, the keyword density in the article, the page other elements of the article, we often do not take into account, then this is wrong?   Analysis: The reason to define the concept of keyword density is because the keyword density affects the search engine on the Web page classification and analysis, so I think, the keyword density of the calculation of the main body is the article or the entire page, to be divided into two kinds of situation, a situation is: the Web page and the high correlation between the HTML > Sometimes the articles we post are not very relevant to this page, then we will use the article for the calculation of the ontology, my reason is: the Web page and article relevance is not high, that is, with the article keyword relevance is not high, that is, in addition to the article outside the page elements can be stripped from the calculation body, To increase the relevance of the article and the keyword, if the relevance of the other elements of the page is not high, then it is like a cup of sugar into a glass of water, will dilute the density of sugar syrup. Cause keyword density analysis is inaccurate. The second scenario is that the Web page is highly correlated with the article, for example, for the theme of this page to write a specific article, then I think at this time in the calculation of keyword density, the entire page should be the content of the calculation as the main body, here I still for example: there is a cup of sugar, the lower half of the cup due to the precipitation of sugars, The concentration of 70%, the upper half of the cup concentration of 65%, then, in the calculation of sugar concentration, we are only to calculate the concentration of the second half of the cup, or first to the sugar mixing to calculate it? I think we all know the correct answer. So this is used in the calculation of the density of keywords, the same applies.   Question two: The keyword density must be evenly distributed  SEO people know that the keyword density must be evenly distributed, this knowledge point is almost the same as the concept of keyword density appeared, here I want to ask questions: keyword density must be evenly distributed?   Analysis: I think the keyword density distribution also need to be divided into two kinds of circumstances, the first case is: the page 70% of the content of text, then this case, I think the keyword should be evenly distributed better. My reason is: a Web page in the text accounted for 70%, the search engine in the analysis of the content of the page has a lot of reference words, if the keyword distribution is not uniform, it is easy to be mistaken for the search engine "stacked keywords", so that this page will be punished. The second scenario is that 30% of the content in the Web page is text, this kind of web page is common in the video station, the picture station, the game station, roving and so on website page, on the keyword density, this kind of page's keyword distribution is not good to grasp, because they generally have the fixed template, and the text content is very few, the distribution also is very concentrated, Not because the site owner does not understand the optimization, but for the user experience degree of consideration. So for this kind of Web page, believe that the distribution of keywords do not dwell on the concept of "uniform", but to pay attention to the "finishing touch", that is, the keywords in such pages to be placed in the picture or video introduction, games and activities on the note, and the introduction and note must be in the eye-catching position, This kind of keyword annotation can let netizen see at a glance, know this video or picture is what content, thus enhance the user experience degree; This annotation can be very good to the search engine accurate interpretation of the page is not a text element of the central meaning of what.
