Certain Domains no longer recognised by open site explorer

[NigelJ]

Afternoon everyone (well, it is for me),

We've been tracking the linking root domains to our domain for around 6 months now, alongside tracking these domains we have also been engaging in linking building activities. Our initial activities worked quite well with linking domains rising from around 620 to 720 in 3 months.

However, recently we have seen those numbers begin to fall away, in many cases it is because certain domains have stopped linking to us, have become no=follow sites or have been archived. But, in some cases we can see the link is still there, and is being registered by other tools such as yahoo or webmaster tools.

My question is really, does anyone have a way of working out why a link, that was in the past being registered by open site explorer, is no longer registering and presumably no longer passing over juice to help with domain authority. What kind of signals should i be looking for to tackle a 'decaying' link?

Looking forward to hear your thoughts!

I personally doubt these links (or any links for that matter) are 'decaying'.

Knowing that SEOmoz only crawls a portion (however large, but still a portion) of the pages on the web, these pages that were once showing up containing your links, may simply not be crawled anymore due to being 'not important enough'.

To either strengthen or break the theory above: are these 'decaying' links coming from authorative / strong domains or from weaker domains that could possibly be fallen out of the crawling range of the SEOmoz crawler?

Thanks for your thoughts.

Having looked into it, we've got 10 linking root domains which used to register through SEOmoz but are no longer doing so whose domain authority is above 70. This would suggest that they are still important enough to be crawled, however I guess I would need to get the PA of the linking pages that have been lost incase they are less important pages on large domains.

I'll keep this question updated with anything else that comes up.
