Dublicate URLs for every product page and EZ-page

Hello Everybody,

Following a recent installation of V1.5.1, I submitted the main URL to Google for indexing. The following day I looked at Google webmaster tools' HTML improvements section and noticed a massive number of duplicate pages sited by Google. It appears that Zen Cart generated every product page and EZ-page twice. Below are several examples for product pages and EZ-pages:

Store/index.php?main_page=product_info&cPath=4_7&products_id=34
/Store/index.php?main_page=product_info&products_id=34

and

/Store/index.php?main_page=page&id=9&language=en
/Store/index.php?main_page=page&id=9

Did I mis-configured something or is this a normal conduct by Zen Cart?

Thank you very much.

With v1.5.1 your product_info&cPath=ZXY&products_id=ZZZ will automatically tell Google that the actual content is the version without the cPath in it (that's because a product could exist in multiple categories, and can be accessed without specifying a category at all ... so no cPath is actually required). So, either yours is broken because of using old code, old plugins, or old templates, or Google just has old links in their index that they haven't retired yet after the new canonical links are read.

But, you didn't post your actual store URL, so we can't take a look to offer more useful help.
It's ALWAYS important to post your URL so we can see your symptoms in action.

Thank you for the reply, DrByte.

It is a new installation and I only submitted it to Google 2 days ago.

Below are some examples but judging by the number of duplicate URLs cited by Google (105), I have duplicate pages for every page in the store.

http://www.augustica.com/Store/index.php?main_page=product_info&cPath=4_7&products_id=34
http://www.augustica.com/Store/index.php?main_page=product_info&products_id=34

http://www.augustica.com/Store/index.php?main_page=product_info&cPath=4_7&products_id=38
http://www.augustica.com/Store/index.php?main_page=product_info&products_id=38

http://www.augustica.com/Store/index.php?main_page=product_info&cPath=13_14&products_id=5
http://www.augustica.com/Store/index.php?main_page=product_info&products_id=5

Thank you for looking to this.

All of those links appear to properly output the correct canonical tags.

If you submitted the site via some sort of sitemap tool or plugin, perhaps that's what's malfunctioning.

Thank you for confirming that canonical tag functions properly. I did install several basic addons which most users have. I did not think that any of them dealt with Admin folder. Or at least dealt with the files in Admin folder that could have caused this problem.

No, I did not use any tool to submit to Google. I individually submitted http://www.augustica.com/Store/index.php to Google through webmaster tools and it indexed the rest of URL itself. Then it came with a list of 105 URLs that have identical title and description metatags. Clinking on the links cited by Google essentially leads to the same page but with a different address.

Could it be that the problem (if there is any, as had I not seen webmaster tools, I would not know that there is a problem from the Google prospective) is caused by organization of the files on my site?

Should I just forget about this issue or do what is suggested in this post ? http://www.zen-cart.com/showthread.php?189602-Canonical-Categories

So, what should I do about this issue? Should I make changes as the previous poster suggested or not?

Thank you.
