Search engine in the calculation of the rankings will calculate the relevance of the page keyword, relevance is the ranking process is very important, but also a lot of SEO people are interested in one of the topics, this article from five aspects and everyone talk about search engine relevance calculation. When a user searches for a keyword, search engine needs a lot of processing to return the user want the results, generally will first deal with the search word, and then file matching, and then to determine the initial subset, in a certain range of the initial subset, is the page relevance of the calculation, it has a great impact on the rankings. It is also welcome to correct the main factors affecting relevance today and from five aspects.

First, the keyword commonly used degree: Commonly used keywords to search ranking contribution rate is less than the keyword. Some of the most commonly used stop words, such as "Ah", "" "and so on the contribution of the ranking is smaller or even zero. Search engine on the keyword is not the same treatment, the word will be different degrees of different degrees of weighting, commonly used words weighted low, not commonly used in the weighted high, will give less commonly used words more attention. For example, we search the word "we rent a car", the weight of the car rental is slightly higher, if there are two pages A and b,a in the title H tag, b car rental only appears in ordinary text, then give a Web page relevance is higher.

Second, the frequency and density of words: Theoretically a page appears the more the keyword more representative of the more relevant, the more the page is related to search terms, but the actual situation is not so, search engine to judge the relevance of the page will not only see the frequency and density of keywords, but also many other factors, In addition many webmaster will have unconscious accumulation of keywords, easy to fall right, so, now the search engine for keywords appear frequency and density of the degree of less and less attention.

Third, the position and form of the word: keywords in the Web page in the location of different get the weight is not the same, search engine will be the keyword in the page appears in the location and format are recorded in the index library. Generally considered more important position has the title tag, bold words, H tags and so on. If the keyword appears in the important position or takes the important format, then will give the higher weight, therefore when carries on the website optimization, must pay attention to the keyword appearance position and the form. These details need to accumulate over time, the weight of the site is also slowly increasing a little bit.

Four, the distance between the words: Search engine will search the string for participle, if the word after the segmentation can be a complete match of the appearance, it is the most relevant words and search terms. The correlation between successive and complete occurrences is higher than that of the individual. For example, if we search "Beijing seo", a page appears a complete matching word "Beijing seo", while the B-page appeared "Beijing" and "SEO" two words, and not linked together, then the search engine gives a page of the relevance certainly higher than the B page. Therefore, to do the site before, research and analysis of keywords is very meaningful, from all aspects of the site to play a role, and not only reflected in the number of users, but also reflected in the cumulative weight.

The relationship between links: In addition to several factors on the page itself, the link before the page is also an important aspect of the impact of relevance. The importance of anchor text in links is paramount. If a page has more import links with the keyword anchor text, the more relevant the page is. Search engine personnel in the optimization time must pay attention to the use of anchor text, external anchor text and internal anchor text is equally important, but at the same time not all using a same keyword, to do natural.
