(If there is no search engine optimization training, it can be said that not many people know that the website has internal links. In the past, as a website, I just added content to the site and seriously exchanged friendship links. Not to mention, the sites built at that time have gradually grown into the current big sites. Since search engine optimization has been popularized, it can be said that few of them have been built into big sites through search engine optimization. Many people are using mass messaging software for external connections now.)
