How to understand Link Detective results

[theLotter]

When running my website on link detective I found that 40% of my links were unknown and 41% were dead.

I have a very strong affiliate network and it seems like most of the unknown are from affiliates.  How should I interpret the dead links - is this harming my site?

Thanks!

I assume the dead links can be A. Broken or B. No longer linking to you - It may not mean the site is not linking to you as they may have moved the link to another page etc. just that the exact link that have previously been seen, is no longer.

If the links gave you a rank boost, and are no longer linking to you - yes they could harm your site in terms of rank loss, otherwise I would not worry too much.
