Search engines will calculate the relevance of page keywords when calculating rankings. Relevance is a very important part of the ranking process. It is also one of the topics that many search engine optimizers are interested in. This article will detail it from five aspects. Talk about search engine relevance calculation. When a user searches for a certain keyword, the search engine requires many aspects of processing to return the results that the user wants. Generally, the search term will be processed first, then file matching will be performed, and then the initial subset will be determined. Within a certain range, the search engine will After the initial subset of , there is the calculation of page relevance, which has a great impact on rankings. Today I would like to summarize with you the main factors that affect correlation from five aspects. Your corrections are also welcome.
First, the degree of common use of keywords: The contribution rate of commonly used keywords to search rankings is less than that of rarely used keywords. Some of the most commonly used stop words, such as "ah", "the", etc., contribute less or even zero to rankings. Search engines do not treat keywords in search strings equally. They weight words of different degrees to varying degrees. Commonly used words have a low weight, and uncommon words have a high weight. They will pay more attention to uncommon words. For example, if we search for the word "we rent cars", the weight given to car rentals will be slightly higher. If there are two web pages A and B, and car rentals in A appear in the title H tag, and car rentals in B only appear in ordinary text, then A will be given The web page is more relevant.
Second, word frequency and density: In theory, the more keywords that appear on a page, the stronger the relevance, indicating that the web page is more related to the search terms, but the actual situation is not the case. Search engines judge that the relevance of a web page is not only It will look at the frequency and density of keywords, and will also take into account many other factors. In addition, many webmasters will pile up keywords consciously or unconsciously, which is easy to be demoted. Therefore, search engines now pay attention to the frequency and density of keywords. The degree is getting lower and lower.
Third, the position and form of the word: Keywords have different weights depending on where they appear in the webpage. The search engine will record the position and format of the keyword in the webpage in the index database. It is generally considered that the more important positions include title tags, bold fonts, H tags, etc. If the keyword appears in an important position or adopts an important format, it will be given a higher weight. Therefore, when optimizing the website, pay attention to the position and form of the keyword. These details need to be accumulated over time, and the weight of the website is slowly increasing little by little.
Fourth, the distance between words: The search engine will segment the search string into words. If the segmented words can appear in complete matches, it means that they are most relevant to the search terms. Consecutive complete occurrences give higher correlation than separate occurrences. For example, if we search for "Beijing SEO", the complete matching word "Beijing SEO" appears on web page A, and the words "Beijing" and "SEO" appear on web page B respectively, which are not connected together, then the search The relevance given by the engine to web page A is definitely higher than that of web page B. Therefore, before building a website, it is very meaningful to research and analyze keywords, which can play an role in the website from all aspects, not only reflected in the number of user searches, but also reflected in the accumulation of weight.
Fifth, the relationship between links: In addition to several factors on the page itself, the link relationship before the page is also an important aspect that affects relevance. The importance of anchor text in a link is of utmost importance. The more incoming links a page has with keywords as anchor text, the more relevant the page will be. Search engine personnel must pay attention to the use of anchor text when optimizing. External anchor text and internal anchor text are equally important, but at the same time, do not use the same keywords all and be natural.
So far, a summary has been made from five aspects: commonly used and uncommonly used, frequency and density, position and form, distance between words, and relationship between links. After reading this article, I hope that the webmaster will have a better understanding of search engine relevance calculations. In reality, search engines may be much more complicated. Here is just a summary of the basic principles. Understanding these can play a certain guiding role in our website.
