In the "ancient times" of search engines, search results are arranged in the order in which search engines locate matching web pages in the database. However, people soon realized that such search was ineffective. In fact, users are most concerned about how to find what they want in the shortest time. Therefore, they have higher requirements for search engines, that is, they are not limited to simply returning database search results, these results should also be re-processed to determine which best matches the user's search intention, and then prioritize the most matched web pages. This is the most basic principle for a search engine to play its role-the relevance principle. Some people have promoted it to the "First Law" of the search engine ".
From the perspective of search engine login, the relevance principle is also significant to websites. We always want to give priority to our website information in the search results to attract more visitors. Therefore, we need to understand the rules of the search engine in terms of website ranking, it will be of great help to log on to the search engine and obtain the desired ranking.
Because the "relevance" of webpages is the ultimate goal of webpage optimization, we need to further explore them.
Relevance refers to the degree to which the website information meets the search criteria. When determining the relevance of a search engine, it is basically based on the "Match/location/frequency" principle of keywords on the web page, that is to say, the more words, phrases, or phrases in the website content match the keywords entered by the user, the more frequently they appear, the higher the association degree of the website and the higher the ranking in the search results.
With the continuous development of the Internet, the search engine technology is also constantly improved. In order to provide users with more valuable search services, the engine has gradually introduced the concept of website themes and popularity in the ranking rules based on the original relevance. The concept is embodied in: the more concentrated the content and themes of a website, the more external links related to the website, the higher the click-through rate of the website, the higher the ranking.
Of course, this is based on information association. Even if your website has a prominent topic and is very popular with visitors, but if the content does not match the user's search criteria, you still cannot get a good ranking. This is not hard to understand.
