Redirect for Duplicate Pages ?

[kwikstand]

I am trying to clean up my SEO and Google Webmasters is telling me I have 1656 duplicate titles and 1220 duplicate meta descriptions. It looks like most of the problem is because of the original product and category URLs.
For example:

/Original-Flannel-Lined-Dungarees-P815.aspx
/Original-Flannel-Lined-Dungarees-P815C55.aspx
/Original-Flannel-Lined-Dungarees.aspx (my custom url)

Do I need to do a fixed redirect for each of these variations to point to my custom url?

Also, what about the mobile versions?

/mobile/work-jackets.aspx
/work-jackets.aspx

and the multitude of other variations such as:

/work-jackets.aspx?s=Name%20ASC&p=1
/mobile/work-jackets.aspx?s=IsFeatured+DESC,+OrderBy+ASC,+Name+ASC&p=1
/mobile/work-jackets.aspx?s=IsFeatured+DESC,+OrderBy+ASC,+Name+ASC&p=3

I am using GoldR8 V. 7.0.88.7345

How is supposed to be dealt with?

The canonical link in your page was created to tell the major search engines what url to use. It is like this.
<link rel="canonical" href="http://www.contractors-solutions.net/Or ... arees.aspx" />. That is the link they are supposed to recognize for the 4 links you mention below, including the mobile link.

For the multiple paging and sorting links, major search engines are supposed to be smart enough to disregard the query string.

You could check Google webmaster tools/contact Google if you have more questions/need more explanation.

Edit- I see your other question. You must have some custom code that is causing that.

Judy,

Thanks for the response. After posting this, it occurred to me that the canonical link issue is probably causing this. I looked into the PageHelper.cs file and found some custom code that Drundo must have inserted. (I am hosting with them). I put a tech support request in and I am waiting for their response.

It looks like this:

//DrundoSoft : R5 to R8 Code Merges
if (catalogObject.NavigateUrl.ToLowerInvariant().EndsWith("default.aspx"))
{
objectUrl = objectUrl + page.ResolveUrl("/");
}
else
{
objectUrl = objectUrl + page.ResolveUrl(catalogObject.NavigateUrl);
}
.......................... and it goes on after this
