In the process of website optimization, keyword Mining is certainly the key work, and after the construction of the content of key words is the most important, we said that the construction of the content must be the key words to improve and expand, the theme must be closely around the selection of keywords. But there is a problem, often see someone said in the construction of the content can only join the selection of keywords, can not join with the key words synonymous, synonyms or related keywords, the answer is very unified: that this will reduce the main keyword density, reduce relevance, affect the search engine judgment. Is that really the case? Wood and wood seo think is completely can add these keywords, below I will talk about personal views.
1, increase the relevance, reduce the optimization traces
Synonyms and the keyword to optimize is a meaning, these synonyms can be used to indirectly improve the density of the main keyword, to avoid the stack of a word caused by the optimization of excessive, not only can increase the relevance, but also reduce the optimization traces, naturally reasonable to pave the relevant words, to avoid the forced addition of a word, It is also logical to let the content and the main keyword more relevant, but also to ease the word to bring the user visual fatigue, boredom. To give a simple example, in the optimization of the word "web space", if the entire page is a Web site space, site space, will give users a sense of oppression, can properly join the host, virtual server and other words, not only related to and alleviate the pressure of the main keyword.
2, to supplement the main keyword
The content of the page can be appropriately incorporated into the change of the keyword, including synonyms, synonyms, related words, the same thing different address. In particular, there are ambiguous or multiple meaning of the key words, often a single word is not perfect, can not better highlight the meaning of this keyword. For example, the teacher's English name is "boson", pure this word who knows what is, direct translation or even "boson" meaning, search engine simply do not know what your content theme is, but if in the optimization process to join the word, teacher and other words, so that these words in the main content of the intersection, Soon the meaning is clear, search engines can also better classify the content. So a lot of time to add some synonymous with the main words or related words can better supplement the main keyword, let search engine better put you into the corresponding bowl.
3, semantic relevance, support ranking
This is the most important point, the first 2 in the final analysis can also be included in this point, we have to focus on the point. When it comes to semantic correlation, you have to say the semantic theme, the semantic theme is the hidden theme in the text, which is a concept that manifests itself in a series of related words, a topic that contains a number of words that appear to have higher probability, and which have a strong correlation with the subject, which together define the subject. And the semantics of these words in a subject are all related.
Semantic relevance to the keyword ranking plays a supporting role, the search engine included content, found that some keywords appear together a lot of times, can form a common topic, so that these words into semantic related words. When these semantically related words appear together to form a common theme, the relevance of the core keywords of the page plays an enhanced role, and the rankings are promoted, which is much more powerful than a simple keyword.
For example, search "SEO optimization", the search engine may give the inclusion of "search engine optimization", "website optimization" and "SEM" content better rankings, there may be "SEO optimization" The word appears little or no appear in this source. For example, if you search for an "apple phone", the search engine's results include "apple," "iphone," "Apple," "iphone," and so on will certainly take advantage. Search engines need to contrast the semantic relevance of content, by searching for the word "apple phone", search engines can find the common themes of "apple" and "mobile" two, and can find many words under the same theme, meaning that semantic search can interpret words and similar words in key words. This improves the accuracy and relevance of search content information and user search terms, and improves the ranking of core keywords, which is much more relevant than a single word.
4, the synonym itself is a search term
Different user perceptions are not the same, so many times the search word will not be the same, a meaning of the word many times different users search is not the same, so in addition to synonyms, not only did not affect the original content of the theme, and the intangible also optimized the synonym, This increases the number of times the page can be searched and the number of times it can be displayed, such as "PS" and "Photoshop". In this point, rather than add synonyms, it is to add the keyword change form, according to different users of different needs of the keyword change form, but in the process of change there is a point is must pay attention to, is the change form and the main keyword is a meaning, same.
In English page optimization There is also a special keyword change form, is the same root generated by various forms of words, such as teach is the root, it changes in the form of teacher, Teachers, teaching, teached and so on. These forms of change are used to enable search engines to extract page themes more quickly and accurately, and these changes are likely to be searched by users, combining more search terms.
5, the phrase can be split up
Another point, search terms in the Search engine processing time will be analyzed, so not only the search words to complete match appears in the page the most weight position, the word can be split after the individual is now several times in the body. This is also a way to improve the ranking of the main keyword. For example, to do the "SEO Research Association Network Forum" This long tail keyword, then in the important position of the page must be a complete match appears "SEO Research Association Network Forum" This keyword, but also suggested that "SEO Research Association network", "SEO forum", "SEO Research Association Forum" can also appear separately several times. This is also to increase the density, improve the relevance, but to pay attention to primary and secondary.
Written in the last
In the optimization of a keyword, you can use synonyms, synonyms, related words to help highlight the theme, improve relevance, improve the ranking of key words, increase the exposure rate. But you must be careful of the primary and secondary distinguish the weight, and in the process of building these synonyms, related words, and the optimization of the main words, can not be random piling, can not be separated from the original page of the core theme, also can not affect the content of the main keyword, not to affect the user reading, in short, these synonyms, related words When to use, where to use, how to use, etc. must be based on a core principle: to help users better read and understand the content of your Web page.
Note: Do not lose, on the one hand reasonable layout of the main keyword, on the other hand, and in the piling up these times related words, you think is normal optimization, in fact, these times keyword optimization is around the main keyword, in these words cheating is tantamount to the core keyword cheating, so don't lose the candle!
