seo training

The page is a must-have page for every website, and it is very important for you. It tells the viewer that the page they are visiting does not exist, that the link entered is wrong or that the link has expired, and guides the viewer to browse other pages of the website instead of closing the page or leaving immediately. If your website has no pages, there will be dead links, which is not good for spiders to crawl, and of course it is bad for the inclusion of the website.
