Optimize My Web Site Dictionary

200 - Status OK

The file request was successful. For example, a page or image was found and loaded properly in a browser.

Some poorly developed content management systems return 200 status codes even when a file does not exist. The proper response for file not found is a 404.

301 - Moved Permanently

The file has been moved permanently to a new location.

This is the preferred method of redirecting for most pages or websites. If you are going to move an entire site to a new location you may want to test moving a file or folder first, and then if that ranks well you may want to proceed with moving the entire site. Depending on your site authority and crawl frequency it may take anywhere from a few days to a month or so for the 301 redirect to be picked up.

302 - Found

The file has been found, but is temporarily located at another URI.

Generally, as it relates to SEO, it is typically best to avoid using 302 redirects. Some search engines struggle with redirect handling. Due to poor processing of 302 redirects some search engines have allowed competing businesses to hijack the listings of competitors.

404 - Not Found

The server was unable to locate the URL.

Some content management systems send 404 status codes when documents do exist. Ensure files that exist do give a 200 status code and requests for files that do not exist give a 404 status code. You may also want to check with your host to see if you can set up a custom 404 error page which makes it easy for site visitors to Search engines request a robots.txt file to see what portions of your site they are allowed to crawl. Many browsers request a favicon.ico file when loading your site. While neither of these files are necessary, creating them will help keep your log files clean so you can focus on whatever other errors your site might have.
