How does GOOGLE rank websites with keywords?

The search engine uses the relevance of keywords to determine the order of webpages. For example, if someone searches for "butterbeans", a webpage titled "The Butterbean Bazaar" with more than 10 words "butterbeans" may be placed at The top of The search results; websites that only appear "butterbeans" once or twice are arranged at a later place; those with the word "beans" on the website are placed at a later place; websites with only the words "beanless" won't appear in the search results at all. Each search engine has its own formulas for sorting search results, and they are saved as confidential information. However, the basic rule is that the more times a keyword appears on a webpage, the higher the relevance between the webpage and the keyword, and the higher the ranking of the webpage in the search result. In addition, keywords in the webpage title and chapter title are more relevant.
With the knowledge of this rule, many "smart people" arrange a large number of popular words such as "mp3" and "free" on their webpages. Some articles introduce cheating techniques for ranking improvement, such as "invisible text" and "hidden keywords". These tricks are widely used or even wildly, greatly reducing the search engine's query performance. Obviously, if you do this, the search engine will become useless sooner or later. One day, no matter what you search for, you may always get pornographic websites. Therefore, the search engine launched a fight against cheating. As long as they suspect that you are interested in the "manufacturing" keyword, your registration may be canceled.
For example, currently, many search engines do not accept registration using "invisible text" websites.
In fact, the use of "keywords" is like a "Double-Edged Sword". On the one hand, your webpage should contain as many keywords as possible to make your website rank top in the search engine. On the other hand, once the registration process is excessive, you may be at risk of canceling the registration. Therefore, registration with search engines is not a top priority. What really matters is that the website must have good content, products, services, and design effects. In addition, it is to make your webpage and search engine friendly. To put it bluntly, you must use keywords as appropriate, second, we should avoid "offending" search engines and avoid using design technologies that can easily make them "misunderstood", such as frameworks and dynamic web page registration. Then, how can we use keywords to make it appropriate?
Find out all the words (keywords) that people may use when searching for such websites, and link them as much as possible to give a brief description of your website. For example, if you want to sell butterbeans (cotton beans) and you have listed the following keywords:
Butterbeans
Beans
Lima beans
Biscuits
Southern cooking
You can write the description as follows:
"We recommend butterbeans and lima beans, which taste great with biscuits and other Southern cooking. Free butterbean recipes and a butterbean discussion forum ."
