and whether basic 404 error topics need to
be considered by every SEO practitioner~!

If you try to review some well-known and
established websites, you will find that a

inevitably generate some incorrect links,
which will cause URLs to not be accessed
properly.

poor user experience on the page, such as
the inability to open old content.

serious.
