When reading SEO articles, we often see some statements about dead link error links. So today, Gu gifted to explain what is dead link and what is the wrong link?

What is a dead link?

Simply put, the dead link refers to a link that was normal and later invalidated. When a dead link sends a request, the server returns a 404 error page. The following are some of the factors that make up a dead chain:

1. Dynamic links become dead links under conditions that the database no longer supports.

2. A file or Web page moves the location, causing the link to it to become a dead link.

3. Web content updated and replaced by other links, the original link into a dead link.

4. Web server Setup error.

Second, what is the wrong link?

The so-called wrong link, usually we refer to: There is no link, that is the wrong link.

There are several factors that make up an error link:

1. The user misspelled the domain name.

2.URL Address writing error.

The 3.URL suffix is redundant or lacks a diagonal lever.

The letter capitalization that appears in the 4.URL address does not match exactly.

What's the difference between a bad link and a dead link?

Error link is due to user's negligence, the requested link does not exist. The dead link is the original access to normal, and later because of the changes in the site can not access. From the user's point of view, dead link and Error link performance is the same, so generally we do not need to distinguish between dead link and wrong link. As SEO personnel or webmasters, we should try to avoid the death of the site link, because the number of dead links can be judged by the authority of a site.
