multple urls for a product with multiply categories

[kiasati]

Hi

i have a "bullet hd camera"
the categories are:    camera --> hd-camera --> bullet-hd-camera
bullet-hd-camera is a subcategory for hd-camera and hd-camera is a sub-category for camera

i assigned the product to all the 3 categories so when a user clicks on hd-camera in the menu, the user could see all the cameras in hd-camera's subcategories including bullet cameras.

the problem is the product has 3 different urls.

1. sitename.com/camera/the-pruduct-detail
2. sitename.com/camera/hd-camera/the-pruduct-detail
3. sitename.com/camera/hd-camera/bullet-hd-camera/the-pruduct-detail

and thats totally bad seo-wise

how can i have only the third url for the product?
how can i solve this.

another problem is recently only the third product page displays correctly

Sounds like you may not be loading jQuery

how can i fix it?
how can i eliminate multiple urls for one product?

[jenkinhill]

Fix the template. Multiple URLs are not usually an issue, it is canonical urls that are important.

You can enable flat URLs in VM configuration -> SEO. But this will also apply to category URLs. If you want to avoid that, you'll have to edit router.php.

how can i use canonical urls?

should i use any extensions or it can be done by virtuemart itself?

if i should use extensions, does "Canonical Links All in One" or "sh404SEF" help?

what do i have to edit in router.php?

[jenkinhill]

VM creates canonicals automatically. Just look for rel="canonical" in a VM page's generated code.

[antonisdel]

yes the canonical is enable , but  how to how to define the primary url
so google does not see duplicate content on the other links= urls

[Studio 42]

google does not see duplicate content if you have always same canonical and this is the case (or should be) with virtuemart
