after our website selects the key words, it is naturally the keyword planning of the website, which plays a decisive role in the ranking of the key words. So at this time, we need to know how the search engine determines the central keywords in the web page, which also has positive significance for us to rank the long tail keywords. We know that the search engine contains a URL. What keywords does this URL represent? The search engine is just a program, and the program must not be as familiar and accurate as people in judging a webpage keyword. Even sometimes it can be misjudged. So from what aspects will the search engine judge the keywords of a web page? Below, the author announces the results of personal discussion on this difficult problem. Top of the list, the title label of the web page We usually put the central keywords of the web page in the title, so that readers can know what this chapter is about when they are at the top of the list. The search engine also discriminates in this way. It is usually the key words in the center of this page that are placed in the title of the website, which is one of the important norms for the search engine to discriminate the keywords on the page. Speaking of this, it is very important that many people don't realize the work. Let's analyze it here today. I don't know if we have found out, but we can know that the search engine does not extract according to our description, and will take the initiative to grab a piece of content for description. In fact, some time-division search engines don't use our titles as titles, but extract the contents of our web pages as titles. Please let's take a look at the example. This is the result of searching for the word "which is good for Changsha Internet Company" in Baidu. The original title is "which brand of soybean isoflavone is good?" The list of soybean isoflavones informs you. Someone can tell me the same thing, because you look at it from the point of view of the article. If you look at it from the point of view of the website, it will be different. The first search result is directly the sentence "which company Changsha Network Company lists to inform you". There is no question number, but the title of our article is presented in the description. From the perspective of the webpage, the title in the search result is extracted from the webpage by the search engine, and then the most relevant keyword is captured as the description, that is, the intact title is presented in the description we see. What kind of guiding significance does this thing have for us? In fact, the search engine will also match the phrases in your web page when judging the key words in the center of the web page. If there is a maximum match, it may call the phrases searched by users in your web page as the title.
