Search engine's judgment on page keyword

A few days ago, a friend of the group asked me, search engine is how to determine what a page is to do, why the word in this page has rankings, in other pages are not ranked. In fact, this involves a search engine of an algorithm, is the key words and page relevance of an assessment, said the algorithm is a lot of people on the head, the algorithm is a touch, invisible things, and fickle, Zac a saying good, standing in the search engine angle, all algorithms are natural things, Today we are standing in the search engine perspective, from the following aspects to see how the search engine to interpret a keyword and the relevance of the page.

First: The density of the key words

The density of the key words is simply the keyword and the page can be seen the total number of words in a proportion, in fact, this does not need a webmaster to calculate, many tools are available to provide inquiries, as shown:

　　

The original search engine algorithm believes that the number of keywords appear more, that is, the higher the frequency, the page with this keyword more relevant, but now the search engine algorithm has been more complex, webmaster often think of the increase in the density of keywords, here Xiao to emphasize is, do not deliberately to increase the density of keywords, too much, The excessive accumulation target keyword, will let the search engine think is cheating, that gains the candle. The occurrence of the key words to nature, in a bit since we are doing optimization, will certainly make some changes to the page, the keyword in the presence of the time. and appear in important places.

Second: The distribution of key words

The location of the keyword distribution, but also the evaluation of the key words of the page is an important factor, keyword distribution refers to the location of the keyword in the page, the keywords in the page in different positions on the page will have a certain impact on the relevance.

The search engine calculates the keyword distribution value of the page by recording the location of the keyword in the page, thus obtaining the relationship between the keyword distribution and the page relevance. Suppose the keyword "electric circle" appears at the top of the page, its keyword distribution value is 50, and at the bottom, the keyword distribution value is 10, then the keyword "Electric circle" at the same time at the top and bottom of the page, the key word distribution value of the page is 60.

The general requirements of the keyword appears in the first 50-100 of the article, in the label should also be ranked in the front.

Third: Semantic analysis of proximity of key words

For example, a page to do is "electric business Circle", then in the page, the emergence of electricity, e-commerce, and so on similar words are also search engines opposite keyword analysis. Another example, the page is the key word "computer", when the page appears when the computer search engine will be they belong to a class, search engines have their own thesaurus, so sometimes the false original is not very useful.

Part Four: The writing in the label

Search engine optimization, the most important there are 3 places, title tags, keyword tags and description tag. In fact, now the role of the title tag is good, the electric circle competition, a lot of sites just modified the label, ranking on the up. Keyword tags can be written, can not write, Xiao did not write. But maybe writing is better than not writing it. Description of the role of the label is not much, in fact, the role of the description of the label is an attractive click, like Baidu bidding in the creative. Clicks are very important.

V: internal and external use of anchor text for keywords

Many friends do not know "anchor text" is what, in fact, simply say "anchor text" is the key word with the connection, if from the code is "< a heref=" http://www.***.com "> Electric Business Circle </a >" such form. Search engine to judge the relevance of the page and keyword, a lot of time is to look at the internal and external anchor text of the page using what keyword. Especially the internal links, the front also stressed that nothing too much, do not think that anchor text point is very important, on an article are anchor text to the same page, the Search engine optimization emphasis on nature, emphasizing the user experience degree.
