A lot of friends are trying to optimize their website, because of the unfamiliar search engine, and the Internet on the induction of articles, resulting in exhaustion and skill play, in the end can not get the desired rankings and traffic is not very difficult to relatively durable access to rankings and traffic here is the main reason, is the lack of understanding of the essence of search.

First, find out what forms of search are being worked on:

The current search engine is based on "word items" in a series of sorting calculations.

This is a good understanding, the computer can not be the natural language and computer language direct conversion or calculation, that is, can not make semantic judgments and calculations. Although there is the concept of recessive semantic retrieval, it is not a real speech retrieval, and the scope of application is very limited.

Search "Mouse's World" If you enter the word, must be to obtain the "cat" information, this is the fundamental meaning of semantic understanding, but search results or around the "mouse" "natural enemy" to retrieve the results, there is no and "cat" word items have relations, so, alone, Search is not currently available or computer technology does not reach the realm of semantic retrieval.

Well, to say a bunch, the word item is the basic factor of the search as a sort calculation.

In the future, we do not have to go to other places to think, good word, is the fundamental optimization.

The second is to understand how keywords are generated:

It's also a pretty interesting concept:

Optimization of a lot of time is the essence of keyword optimization, of course, not excluding the whole station optimization, strategy optimization and so on.

But what is a keyword?

Search how do I confirm the keywords for this page?

Do you think it matches the calculation of keywords and search?

Wait a minute.

These simple questions are also the basic puzzles that primary optimization faces.

First, what's the key?

Based on the current search for the ranking of the Web page, I summed up a sentence: "In the search for words, you can find the page, then the word, relative to the page is the key words."

Of course, search is based on full-text retrieval, so this does not represent a large segment of the character search.

How is keyword search computed?

This is also a technical problem, in the process of inverted, as to how to calculate the search, in principle I do not know, and will not know, but the principle is very simple. The inevitable matrix, as well as the word for the relevance of the document quantification is inevitable, of course, you can obtain this word or the value of the string and document correlation quantization or error values through the vector space or the second linear approximation of the string.

So for each word and the calculation of the document, it will make every word to get a value, and then form a queue, in principle, I observed Baidu take its top five high value words as the theme of the page document, carry out the inevitable follow-up calculation. That's the basic principle of keyword creation.

The wrong place to correct me!
