If you want to do SEO, of course, inseparable from the web site correlation optimization.Correlation of SEO, is refers to when a user searches for a keyword, the search engine will first from a large number of sites in the database search and search terms to display the most relevant web site.As for a correlation between the higher, the website to the top.Search engines determine the correlation of website and the search term, will be based on a variety of factors, and then gives a comprehensive score.
The following to analyze the correlation between main reflected in which aspects:
1, title, description, keywords tag
In a web page, the more depend on the content of the more important.And came to a web site search engine, what is in the first reads the title tag information, etc.And the label is also such as the title of a web page content summary, so this is the most important place in the search engines to determine correlation.The Title is the most important of all the factors, which affect the SEO ranking one.In the title of the web is generally distributed into 3-5 core keywords, if necessary through the long tail keywords to repeat it again.Web site is semantic coherence of the title of the best short sentences or phrases, must not be repeated stack keywords, this is very bad for the user experience, but also for search engines to suspected SEO cheating.Semantic coherence of a paragraph should be in the Description, is composed of a few sentences, his content should be a summary of the contents of the page.As far as possible in the description into the long tail word associated with core keywords, this helps increase the keyword density, can also be integrated into more users search term.Due to the title and description information will appear in the search results page, so this is also the user willing to click on the basis of access to the site.Therefore, when we write the title and description information, first of all, should consider the user experience, is actually the principle of search engines.Keywords tags in today has been greatly weakened, the action of many websites has not been written just skip.If we piled up too many keywords in the keywords tag, but also have side effects, it is good to write several core keyword Suggestions.
2, web site navigation
The top of the site navigation bar in general, no matter for the user, or is a very important part of the search engine, often assign weights is also very high.So we can put some more competitive keywords is layout in the column, column, of course, the layout of the keywords should also with the site as a whole has a certain correlation.
3, the content of the site
Before always have "content is king", but want to and the content of the site is also very important part of it.A website in addition to the need to have good design style, also has a high quality of the content of the foil, our website will be more popular among the search engine.So content when we are looking for as far as possible to be consistent with the theme of the site, if we are a website is associated with SEO, so we send a lot of current news, that can think and does not match at all!
4, related links
Key link that is anchor text, people often say that is very important for SEO, second only to the title tag.Keyword links are divided into internal links and external links, both for the keywords ranking has a significant effect.Internal links is directly the same sites page keyword links, external links is other website links to our web site keywords.It is often said that the link is a kind of external links, links, of course, the correlation of also has a certain relationship with their own site keywords ranking, otherwise there will be no so many links commissioner, every day to find related links!
The Internet resource is Shared by the link, so the search engine is a very important link of text and links.Internal links are often through the navigation text, bread crumbs navigation links and keywords in the content page.Outside the department links usually through links, blogs and BBS on outer chain.External links the site must be and is content related to our site, outside the chain to achieve a better effect.
Search engine on the ranking of computing page keyword relevance, relevance is a very important part of the ranking process, is also a lot of search engine optimization (seo) researchers are interested in one of the topics, this article from five aspects and talk fine correlation calculation of search engine.When a user searches for a keyword, the search engine needs a variety of processing to return the user want, usually first tackle the search term, then file distribution, then, to determine the initial subset after identified a certain range of initial subset, is the calculation of correlation with the page, it's very big impact on rankings.Today and everyone from the five aspects to summarize the main factor affecting the correlation, also welcome to correct me.
1, the position of the word, and form: the location of the keywords in the page different weight is not the same, the search engine will take the position of the keywords in the page and format are recorded in the index in the library.Generally considered the more important the position of the title tag, boldface, H tag, etc.If the keyword appears in the important position or take important format, so will give a higher weight, so the site optimization, to pay attention to the location and mode of the keyword appears.The weight of these details need to accumulate over a long period, the website is also in a little increase slowly.
2, keywords are commonly used: common keywords to search ranking the contribution rate of less than very with keywords.Some of the most commonly used to stop word, such as "ah", "" contribution to the ranking smaller even to zero.Key words in the search engine to search string is not alike, to varying degrees of different degrees of weighted word, commonly used word weighting is low, not commonly used weighted high, to not pay more attention to commonly used words.Such as we search the word we rent A car, for the weight of car rental is A little higher, if there are two pages A and B, A rental car appear in the title in the H tag, B car rental is only appeared in the plain text, then gives A correlation of the web page is higher.
3, the relationship between links: in addition to a number of factors, on the page itself before the page link relations are an important aspect of relevance.Link anchor text in the importance of the most important.If a page has the more keyword for the anchor text of inbound links, the greater the page relevance.Search engine personnel must pay attention to the use of anchor text when optimization, external anchor text, anchor text and interior are equally important, but not all at the same time department with the same key words, to achieve the naturalness.
4, word frequency and density: in theory, a page of keywords on behalf of the correlation is stronger, the more that the web is related to the search term, but the reality is not so, judge the correlation of web search engine will not only look at the key word frequency and density, and also of many other factors, also many webmasters will be conscious of the unconscious accumulation keywords, vulnerable to fall right, so now the search engine for the frequency and the extent of the density value of the keyword appears more and more low.
5, the distance between the words: search engine to search string segmentation, if the word segmentation after can complete matching appear, is the most relevant to the search term.Consecutive complete appear to give the correlation of above respectively.For example, if we search "high-tech", A web page A complete match word "higher science", and web page B had "higher" and "science" two words, not together, then the search engine to A web page relevance is definitely higher than B.Website before, so, do research and analysis the key word is very meaningful, can play a role from the various aspects of website, is not only reflected in the number of users' search, will also reflect on the accumulation of weight.
Respectively from commonly used and very use, frequency and density, the distance between the position and form, the word, the relationship between links do summarized in five aspects.Read this article hopes to let the webmaster for correlation calculation have a further understanding of search engine.In practice, the search engine may be more complicated, here are just gave a summary from the basic principle, understand these for our website can play a guiding role.Hope I can help to the large home!!
