mod rewrite - will i lose rankings

[Guest]

I have a fairly established store that has good indexing by google etc

 

I have installed a SEO Urls contrib that is used by one of the fork OSc Derivatives and it works fine i.e. it changes a url to be as follows in my store :-

http://www.outdoorbits.com/p94/Mapa-Seat-S...oduct_info.html

 

instead of

 

http://www.outdoorbits.com/product_info.php/products_id/94

 

I have no idea whether this does actually improve on your ranking at all btw, just seemed a good idea ;)

 

anyways, my concern is with this switched on the old urls no longer work and produce a product not found page which isn't good !!, is there any way of adding to the rewrites so that if a page query comes in for a product using the old format that it is instead shown the new url ?

I am pretty sure this should be possible

 

my .htaccess file

 

# $Id: .htaccess
#
# This is used with Apache WebServers
#
# For this to work, you must include the parameter 'Options' to
# the AllowOverride configuration
#
# Example:
#
# <Directory "/usr/local/apache/htdocs">
#   AllowOverride Options
# </Directory>
#
# 'All' with also work. (This configuration is in the
# apache/conf/httpd.conf file)

Anytime you change your links, your ranking will suffer. If done properly, they will recover in a short amount of time. You should install the Ultimate SEO contribution since it handles that for you automatically.
