Google webmaster problem with "?Itemid=0" in virtuemart urls

[lextor]

Hello everyone! I own this site http://www.autogadget.ro with Joomla version 2.5.7 and Virtuemart 2.0.26d.
In google webmaster tools I have many links with duplicate title or meta, but these links are with "?Itemid=0" in url, as you can see in attach. For example:
www.autogadget.ro/navigatii-dedicate-gps-auto-dvd/mitsubishi/mitsubishi-l200-2012
duplicate title with
http://www.autogadget.ro/navigatii-dedicate-gps-auto-dvd/mitsubishi/mitsubishi-l200-2012?Itemid=0

So, what's this "?Itemid=0" and how I can resolve it?

Version of VM / Joomla

This is Joomla functionality.  You have 2 different menus that show the same link

Look at the urls they give you and you will see that they are different - this is the reason for your 2 results in google

If you have 2 menu options driving to the same destination you should make one of the menu links a joomla menu type of "alias" to prevent a "different" link being created by joomla.

To "get rid" of them you could use a simple rewriting tool that can do patern matinching a redirect (303) to the "correct url"

You should sort out the duplicat menu content as well.

I have used this for my VM sites to help redirect duplicate urls

but I use sh404SEF for friendly urls....

I simply pointed where I see your issue arising and that is that you have 2 different urls for the same content

Google also sees it that way

Take this issue up with sh404sef team.

Or use Joomla/VirtueMart native SEF, as this was designed not to require a third party SEF extension. You should probebly update your Joomla - see http://forum.virtuemart.net/index.php?topic=118683.0

Agreed Jenkin - use base VM and joomla SEF

And dump bloated sh404sef


Still sort out duplicate menu items with different ids as best practice!

Please use vm2.6.7, as far as we know we removed the Itemid=0 problem
