Remove ?p=n from querystring and 301 to clean URL


Our urls used to be paginated - but we now have AJAX loader.

Our URL's indexed in Google are:

The rewrite rule needs to identify any URL's that contain "?p=n" immediately after ".html" and only on these do a 301 redirect to the same URL but without any querystring.

Ajax is for your visitors benefit, you still need to let Google etc index the paginated pages. Search engines wont execute ajax requests.
If you remove all links to the paginated pages then you will lose all those pages from Google etc. ergo search traffic

Thank you, but we are no longer using pagination - and these querystrings no longer affect the product listing, so it is actually causing duplicate content in Google's eyes.
And how does Google get the rest of the content?
Assume you are registered with Google Webmaster Tools, you can set what params do under the Crawl index.
In your htaccess, this will remove the whole querystring!

RewriteEngine On
RewriteCond %{QUERY_STRING} !=""
RewriteRule ^(.*)$ /$1? [R=301,L]

Try the following.  It detects the "p=..." as the first argument in the query string (as you requested), which may be followed by any other argument which you may want to keep.

So something like "" would turn into "".

RewriteEngine On
RewriteCond %{QUERY_STRING} ^p=\d+(\&(.+))?$
RewriteRule ^(.*)$ /$1\?%2 [R=301,L]

Open in new window

If you dont know if the "p=..." argument is the first one, then you need to use a more complex rule, like this:

RewriteEngine On
RewriteCond %{QUERY_STRING} ^((?!:p=)[^&]*&)*p=\d+(\&(.+))?$
RewriteRule ^(.*)$ /$1\?%1%3 [R=301,L]

Open in new window
