However, there are many other status codes you need to know about as a search engine marketer. The
status codes considered in this chapter are:
Redirection: 301 and 302
Removal: 404
Server Error: 500
The official descriptions for all HTTP status codes are available at
Redirection Using 301 and 302
The 301 and 302 codes are the HTTP status codes used for redirection. These codes indicate that another
request must be made in order to fulfill the HTTP request — the content is located elsewhere. When a web
page replies with either of these codes, it does not return any HTML content, but includes an additional
HTTP header that indicates another URL where the content is found.
Figure 4-3 shows an example of how redirects occur in practice. As you can see, when a redirect occurs,
the URL that issues the redirect doesn’t return any content, but indicates the new URL that should be
referenced instead.
