200 OK
This is by far the most common status code, but there??™s no contingency plan needed
because 200 OK means everything went just swell when the visitor requested the page.
The URL was found, the page was loaded, no redirections were detected, no script errors
occurred, and there were lots of puppies and rainbows. Even though you never see it, this
is the code you want; anything else in this list raises a red flag.
301 Moved Permanently and 302 Found
The 3xx series of HTTP status response codes is a fishy area because although each code is
explicitly defined in the W3C??™s spec, many are utilized and interpreted improperly. Luckily
for developers, 99 percent of the time, a corporate website will only need to use 301
Moved Permanently for permanent redirects and a 302 Found for temporary redirects.
Anything else in the 3xx category will have unpredictable results because of inconsistent
interpretation by browsers.
Redirection has always been at the forefront of discussions about search engine positioning.
Because a lot of malicious web activity relies on sneaky redirects, some methods, like
meta refresh??”which uses a meta tag to handle the redirection??”are universally frowned
upon by search engines because of their lack of security and history of abuse.
