Welcome to the Q&A Forum

First of all - no, this is not good for SEO. not sure that at the moment it is hurting your website but it is far from begin best practice and might cause problems in the future.

I think that EGOL's solution is the best for this issue,

Combining all the 3 versions into one page with "select your format" is the best solution for users and search engines.

if you take this approach (although it means that you need to develop it into your website) the best thing will be to 301 redirect all the URL's into one for every product.

If you rather leave the pages as they are and only deal with the duplication then Canonical tag, as Justin suggested, will be good practice.

I would go with solution NO. 1

Good luck!

You have to understand that footer links are not a bad idea for themselves, but it is important that you don't stuff it - and you did.

I would recommend that you get rid of the brands links - instead I would place a few links with logos for the most known brands that you have. dont forget the ALT. (now I see that you have this above the footer - isn't it enough?)

Second, I would get rid of the duplicate links that you have in the category section in the footer - for example, you have the link "Men's Waterproof Jackets" both under men and under clothing.

Then I would start to think about the links - do I need all of them or can i just settle with the main categories and few subcategories.

This should cut out at least 60%-70% of the links, and then you should be fine..

I think that you answered your own question,
If there is a doubt there is no doubt..

Here are some practical tips for contnet link bulding:

1. create usefull articles - not the boring same old things that everyone are doing. dig in and reaserch to find out what users really want and then give it to them.

2. publish your content in one (!) resource - make sure that it is original and not copyed (especially not from your own website) - you can use copyscape.com for that.

3. after your article is live on the web you should link to it from tweeter, facebook, bookmarks, forums and other articles you publish later on. If your article is really good you can also contact blogers to write or mention it.

4. link to inner pages (products?) - not just your home page.

The bottom line is that you can not get high quality links with low quality work - you really need to put the effort in to it.

Good luck!

Great answer Ryan. One more important note, If you also going to change the domain name it is important to let google know about it in google webmasters tools.

Actually, it sounds like a pretty good idea to accomplish two things,

a. Fresh content to your page - you are right, its probably not the best fresh content you can get there but it have some sort of add value.

b. get social proof for your website and products to increase conversion rate.
