How to remove category and product SEF url option?

Hello, as I read here goo.gl/loSVI is not possible to remove product and category from url.
So, what is the solution if I need to remove it for seo optimization?
What I need is very short url and I dont need to insert category or product.

Thank you

Hi,

You can use the canonical url in the product edition page. To set the default product url to improve the seo.
And there is sef components existing, which can be found on the joomla extension directory.

Each of my products is single, but the same product has different color. In that way I can you canonical url to improve seo? How can I do?

With the plugin sh404sef I discovered all the url that the related product module genereted. After I modify all the url with the one seo optimize.
Thank you

You can use canonical on the main product and/or in the variants.
On the main product edition page, set the canonical url of the product, and if you want seo for only this product and not the variants, so don't change anything in the variants.
Else you can manage the variants and set a different canonical url on it.

But for charateristic is the same?
For seo only the main product page is shown in the serp, not all charateristic.

Yes it's true, only the canonical of the main product is used.

Ok, thanks a lot

Sorry to annoy you with this matter, I have difficults to figure out.

The problem is: the related product module, for example in this page goo.gl/OsO2Q , generate several different urls each times you refresh the page. Sometimes the url is seo optimize(I discovered that url and already created seo alias in sh404sef), but sometimes, when url is still not discovered, is not optimized(you can check because the url is /2013/....)

As I understand, I need to discover all the urls, for all the combinations, for all the products and, for each one, create the same seo alias.
As you understand this is not possible.

What I need is the same url for the same product even I found this product in category A or B or C.
Is that possible?

Thank you, that is what I did.
Thanks
