I realize this is a very old post, but we have found the same issue. We added this to our robots file:

Disallow: /customer/account/login/referer/

When the next crawl runs, will these be removed from the 'Crawl Diagnostics' report automatically?

Have you tried the SEOmoz Crawl Diagnostics report? That will show the 404 errors and the pages on the site that have the links to those pages.

Thanks. Forgot about the 2nd Twitter link. The 2nd FB link actually allows a visitor to signup for the email list and actually does get used, but differently than the FB icon.

We removed the subcategory links from the Decor section as well. This cuts down quite a bit on the number of links. Thanks for your suggestions.

Ryan - Thanks for taking a look.

I believe there are just 2 links each to FB and Twitter - one at the top and one at the bottom. I'll make sure that gets down to 1 link each.

The addresses are linked to help fix some local listings. We've had some trouble with incorrect info in Google Places.

That's a good idea about the links in the decor section. Seems like a good compromise to allow most items to be found easily but still eliminate some links.

Thanks again for taking for you help!

Sure - http://bit.ly/mP3PGv

Not sure about the usual way of sharing links here.

Thanks for the replies. No social media widget - just 1 link to our page on a couple of sites.

Most of the links are for the category and sub-category navigation. There are some footer links that could be combined and some tag cloud links that should just be removed.

I am thinking about whether all the sub-category navigation should be removed. The menus could just contain the main categories. Once those are clicked on, the sub-categories on listed anyway.

The SEOmoz Site Crawl indicates that we have too many on page links on over 9,970 pages. This is an ecommerce site with a large number of categories. I have a couple of questions regarding this issue:

1. How important is the "too many on page links" factor to SEO?

2. What are some methods of reducing the number of links when there are a large number of categories? We have main categories with dropdown menus currently and have found that they are used to browse and shop the store.
