I created this Server Response Header Checker to allow
you to see how the server that hosts your website is handling various situations
like testing for proper 301 redirects when you change URLs on your site or to repair
and prevent canonicalization problems. Proper server response is important for many aspects of search engine
optimization for your website. Search engines do their best to adhere to the rules of the
Hyper Text Transport Protocol (ie "HTTP"), and that's why
you can't afford to neglect thoroughly testing how your site's server responds.
Every time a server receives an HTTP request, its response includes
a prefix or "header", which is a block of information that describes the response
data itself. This includes an HTTP Status Code, that tells the receiver if the request was
successful (code 200), or there was a problem - such as the common code 404 "Page Not Found",
or code 301 "Moved Permanently". For all of the recommendations for situations that installing a
server redirect on your website, few authors mention how you go about checking the
HTTP Server Response Header to insure that you've set things properly.
Of course, since I harp so much about canonicalization
issues, that's where I'm going to start. In the form below, enter the URL for your
site WITHOUT THE WWW subdomain prefix. If you've installed the correct redirect code
in your .htaccess file or IIs Control Panel, the response will be "code 301, Moved
Permanently." A response of "code 200 OK" on the other hand, means that your
server is still not making any distinction between the two URLS and you need to take corrective
Another situation where its handy to have a Server Header Response Checker
is for dynamically-generated pages with URLs that end in ".cgi", ".php",
or anything other than the common ".html". If your site relies on such file names,
its important to know the value for the "Content-Type" field in the response header.
The "Content-Type" setting tells the user's browser program (or the search engine)
the format of the document that it is sending in response to the HTTP request. Naturally,
if you want the end user to see your document as HTML, the Content-Type field should be
set to "text/html" and possibly the Charset designation. Search engines depend on
this field to tell them how to begin to try to scan your documents, and if the Content-Type
setting doesn't match the data you won't get the results you expect. Newer browsers like
Netscape v6.x+, Firefox, Chrome, and others also rely on this information for similar
Now for the header checker itself. Just enter the URL you want to check
into the form below and press the "Check URL" button.

In writing these SEO tips, I'm often reminded of a pearl of wisdom that my high school computer programming teacher passed on from one of his teachers, "Computers are high-speed idiots!" Remember that, and don't let them get under your skin.
