First of all, the impact of the four factors of search engine rankings, the four factors are,
One: Web page information (so that the content of the page with the keyword highly dense)
Second: page weight (this is reflected in the PR value)
Third: User behavior (Baidu will refer to the user's click to measure the relevance of the page and keyword)
Four: directory reference (such as DMOZ yahoo category directory, such as manually edited directory)
In general, we look at the site background statistics will find that the weight of a higher page to get the long tail keyword ranking, but did not get the top keyword rankings. In addition to the competition with the weight of the Web page, but also with "web information" has a certain degree of relevance. This is like your Web page is optimized SEO keyword, but you are in the Hot keyword SEO is not very good rankings, but in some: SEO tutorials, seo search optimization such complex keywords (long tail) in the good rankings. This situation is often reflected in the problem of the eigenvector of the Web page.
In search engine technology, there is a very important concept, but in the popular SEO tutorial rarely seen, this concept is the Web page feature vector
1, what is the Web page feature vector?
The so-called Web page feature vector is through the analysis of the content of the Web page, through the processing of Word segmentation technology, find out the most important to the content of the Web page phrases, words and words, they are arranged in a certain order, it constitutes the content of this web page "eigenvector", "eigenvector" can be seen as a lossy compression of the body of the Web page information, But he is generally adequate in content.
2. The Revelation of Web page feature vector
Using the Web page feature vector to replace the text of the Web page is a principle of search engine technology. The search engine doesn't care about the content of each page, it's about whether it belongs to a topic or a category. Therefore, search engines can only infer the classification of articles, the article's keyword group and the characteristics of the article, can not appreciate the feelings of the article. If you want to express a very important keyword, please do not the whole article is a metaphor!
The search engine implements the characteristic vector computation to the webpage more is the mathematics computation, the different search engine uses the algorithm to be dissimilar. However, in the implementation of the Web page feature vector calculation process is not the most basic algorithm, but participle technology!
We can take a look at this example: http://www.lesishu.cn/se-friendly/meta-keywords-description/(IP for the music, but the article is really good) in this case we can see, Search engine will dynamically crawl the content of the body as a serp (Search engine feedback page) description. This often makes it clear why only accurate, unique meta information can provide a reference for search engines. Many times we see Sina, NetEase on the entertainment articles are relatively short, but can get a good ranking, because the fine short article can let search engine better understand a page "key content." So that it can get a higher ranking on the relevant keywords. Of course, this is also related to the weight of the Web page, links and many other factors.
How to make the information of the webpage and the key word high density cooperate in the general operation:
One: Bold keywords
Second: Related headings (keywords appear on the title)
Three: Imported anchor text links with appropriate keywords
IV: Writing keywords and description information that matches
Five: The alt attribute of the picture
VI: Excessive optimization is cheating, you do not need to know too much, this will allow you to increase the workload while achieving counterproductive results
can refer to:
http://product.pcpop.com/MP3/00000_1.html Such a URL can also be in Baidu to MP3 for the keyword high ranking, http://u.boboqiu.com/on the image of the Alt attribute optimization also does not matter. No words are the same.
This also leads to a series of problems, often stationmaster's trouble.
The content of the forum is difficult to concentrate?
You can read the following article: http://www.admin5.com/article/20090409/141659.shtml
How long should the article be?
Too long articles will make their "web feature vectors" point to the Optimization keyword. The general long-winded can be paged out. It also optimizes PV.
What about the ecommerce site?
Cold, hehe. This question is also my trouble, in the E-commerce industry, pay attention to SEO at the same time, but also pay attention to UEO, which makes a lot of time we have to add user-related information on the content of the product page, such as product "Evaluation" "Delivery Mode" "Use the Tutorial" ... This is the ignore number "but the dispersed information lets" the page eigenvector "not point to the optimized keyword. Has a certain impact on the rankings.
To e-commerce, remember this is n years ago a sentence: the world where there is no bid? (Now Jing Dong, when, are bidding, you should also refer to a copy)
No money, no money to bid, you think do seo simple, do seo easy ah?
Haha, I wish the webmaster the money is boundless. Remember to reply!
