Seo and search engine rules

The Search Service provides a convenient way for all Internet users to find information. It can help users find the desired information service in hundreds of millions of network information records. To some extent, search engines are leading the development of the Internet.

   In the following article, I will describe my personal understanding of search engines and search engine services.

   First of all, as a Seo worker, my job is to study search engine algorithms and find methods or methods that cater to search engine rules through practice and apply them to website optimization work, to improve the ranking of websites. Since I have not been engaged in Seo for a long time, I can only count as a Seo enthusiast and earn some salary to fill my household expenses.

To put it bluntly, I think that as an SEO worker, No matter what position or position you are in, what kind of optimization methods you have proposed, or how many search engine vulnerabilities you have noticed, you must have an understanding of the development or history of search engines, or even research. I remember saying, "History will help you trace the source and discover the source of things! ". Only by understanding and studying the concepts, technologies, and development history of search engines can you effectively understand the rules of the current search engine.

Here, you first need to know the main technical parameters of the original file retrieval function, that is, the prototype of the search engine, its basic operation rules, and understanding of the initial logical operation rules, check the descriptions of related search technology upgrades and new technology patents. Because of these things, the continuous development and update of these technologies constitute the current search engine, and the search engine algorithm, in fact, it is the final result of the logic judgment parameters through these technologies, and then through multiple computations and judgments.

Since most of these materials are copyrighted in English, I suggest that you use the software Kingsoft, or the Chinese/English dictionary, which will help you understand the article effectively.

I recommend an article titled the anatomy of a large-scale hypertextual Web search engine, which is written by Saji-Blin and Larry pages, that is, an academic article translated by Google's two founders before his graduation from Stanford University as "analyzing a large hypertext Web search engine". Google, as the undisputed overlord of Search Engine Services, is based on the theory of this academic article. Effective reading and in-depth understanding, you will find that the current search engine has many parameters and data settings mentioned in this article.

This is also true for Baidu search. Baidu's founder, Mr. Li Yanhong's patent for the U.S. period and the patent for hyperlink analysis are now applied to Baidu search. To sum up, the main meaning I want to express is that Seo should not only focus on the ranking results of the current search, but you may be able to find a temporary vulnerability in the search engine, your method or method can be used for a short period of time, but if you cannot grasp the direction of the search engine, you can understand and master the technical information of the search engine, then you will not be able to maximize Seo.

OK. Here I will describe my personal understanding of Baidu search. In this article, some specific search parameters will be involved, however, to obtain accurate parameters and reflect the large amount of calculations required by specific calculation formulas, I have not performed any specific operations. Therefore, the provided parameters may have great errors. If you are interested in in-depth understanding, you can pay attention to my contact information and discuss it together.

Impact of domain name and space on the search ranking Service

All people who work on Seo know that the space and domain name of a website have a certain impact on the ranking results of search engines and search engines, no one except the search engine developers who participate in the settings knows the following conditions, such as the title, keywords, and description of the webpage I will talk about below, or the factors, they are only a parameter in the search engine ranking result.

The difference is that we can search by different keywords and compare the search results to obtain the approximate answer, which has been well known by many Seo workers, and has been applied to the actual Seo operations.

The website of. com domain names has a ranking advantage over the websites of. CN Domain names under the same conditions. Similarly, a domain name composed of English words has an advantage over a domain name. An independent word domain name has an advantage over a phrase domain name. In addition, there are many similar rules,

    For example, in my personal opinion, the search engine will give some parameters and record them when updating the website space. The following parameters may be used to obtain a parameter based on the space type and determine whether the space is independent. If the space is not an independent space, a variable is provided based on the number of space partitions. Through a constant value comparison or calculation, a final parameter about the website space is obtained. This parameter affects the distribution of website weights.

Baidu's support for new sites

I personally think that Baidu will increase the weight distribution for new sites. This can be seen through the comparison of the keyword search results that are widely defined by the part of speech ). I will not explain it too much here.

Indexing volume Problems

Some people think that the higher the website content, the higher the website weight. I share the same opinion. However, it should be noted that the website weight distribution is not only affected by the indexing volume. A high indexing volume can only be used as a variable to affect the website weight, but cannot determine the weight of a website.

Search engine algorithms, including their rankings, are built on the basis of "fairness and fairness". Even Baidu is the same, even if Baidu has begun to commercialize rankings. The high indexing volume is a kind of recognition by the search engine on the website. I think there is no big impact on the ranking results of the website.

Main factors affecting search ranking

Here, I want to explain my personal point of view. Of course, there is a certain data basis for this point of view. However, the amount of data I am using is not enough to prove my point of view. So here, I just want to share some of my ideas with you. Of course, I will use time to demonstrate and improve these ideas.

Page Content

I don't think it is the most important factor that affects website rankings. It is content, website content, or website page content.

    I hold this idea because of the nature of the search engine, which is essentially the file retrieval function. It is determined that as long as the content on the page meets the search keyword, even if the title, keywords, description and other conditions do not contain the keyword, the search engine will put it into the ranking result. In fact, keywords, description, and other conditions did not exist until the word wide web conference, held in Paris, France, released the himl3.0 code on April 9, 1996. Seo enthusiasts who are interested can search and compare to find out. Of course, with the continuous upgrade of Web Page writing technology, even if there is a keyword in the content of the page that does not have the title, his ranking results do not have a competitive advantage, this is due to the continuous upgrade of the webpage production technology. The reason why I have explained this is to make it clear to viewers that it is the fundamental factor affecting the search ranking.

Page title)

    Title, I believe most viewers are very clear about the role. Here I will only give a brief description. The title initially serves as a brief summary of the page content, generally the title of the article. However, as the search technology continues to upgrade and update, the title gradually changes to a high summary and summary of the page content, and gradually uses keywords as the title's main form of expression, to highlight the subject content of page information and facilitate search engine identification and capturing.
In the search engine ranking calculation, the title mainly focuses on whether keywords, keyword locations, and the proportion of similar keywords appear. The above three points will directly affect the title performance in the search engine.

Keywords (Keywords)

    If the title is a high degree of generalization and summarization of the page content, then the keyword (keywords) is a supplementary generalization of the page content, or a supplementary description, the interpretation of content relevance.

    Key words are used to express the main content of a page in the form of phrases or phrases and to express the relevance of the page content so that the search engine can quickly and accurately identify the content of a page. The search engine will establish a keyword index directory for the search engine based on the order of the keywords on the page, the manually focused Keywords of the page builder and the keyword ratio of the page content. The search engine sorts the keyword search results based on the content of the index directory.

Several main factors affecting the keyword index directory

 Keyword location

    In the search engine's opinion, the higher the keyword is, the more likely it is to be displayed to the topic content of the page. Therefore, the higher the keyword, the higher the weight obtained in the index directory. Of course, the premise is that this keyword does match the page content, and can be recognized by the search engine through the ratio of high keywords in the content.

 Keyword Page Content Rate

    On the page, the keyword occurrence rate determines the weight distribution of keywords by the search engine. A keyword with a high ratio can obtain a better index directory weight.

 Keyword expression in title

    As mentioned above, the keyword position in the title also determines the search engine's emphasis on keywords and arranges index directories through content comparison.

 Keywords in link text

    Search engines believe that the keywords appearing in links can better reflect the link content. Therefore, the mainstream search engines currently pay great attention to links. The keyword can naturally be reflected in the link text, which is a good way to win the favor of the search engine and increase the weight of the index.

 Settings in the image

    Although the current search technology cannot effectively determine the image content, the search engine still attaches equal importance to image settings, this is exactly the same as some opinions on the network. Therefore, the effective optimization of image settings can still affect the overall effect of the website, although the specific effect is not visible.

 Label content

    The content I want to talk about here is the same as that mentioned by many experts on the Internet. The skillful use of labels and font settings is a good way to express this. Although many people look down on this small change, but details often determine the results.

 Topic settings

    It is very important that the topic titles of many websites are usually set by producers or planners Based on the content at will. This completely deviates from the SEO optimization goal and forgets the original intention of the search engine design and crawling.

    The topic title setting, in the search engine's view, is actually equivalent to the Topic Link Page's tetle. the hasty topic title setting will affect the overall effect of the website to a certain extent.

Detailed search engine crawling, computing, ranking, and other processes

 Capture

    People familiar with search engines clearly know that search engines search and crawl web pages through robots or spider crawlers. Crawlers convert the page information into code information and send it to the storage server.

 Storage Server Analysis and computing

    The storage server compresses the web pages sent by crawlers and analyzes the URL and other information of the web page to record the length, size, URL, URL length, and content of the web page, A docid (document number) is assigned to the webpage ).

 Index directory generation

    The indexer retrieves page information from the storage server, decompress the read data, and analyzes it. After counting every meaningful word in the web page, convert to several index items of a keyword (wordid) to generate a list of index items, including the keyword, keyword location, keyword size, and case status.

    In addition to analyzing meaningful words on the web page, The indexer also analyzes all hypertext links on the web page and saves key information such as anchor text and URL pointing to the anchor document library.

 Ranking of search results

It is actually the ranking of the keyword index item comparison result.

      Since I have not been involved in Seo work for a long time, here is just some of my points of view. Some points in the article may be incorrect. Please help me to correct them. Here, thank you!
