Inbound Link Discrepancy: Campaign vs Open Site Explorer

[truckguy77]

Hello,

I am getting starkly different inbound link amounts from Open Site Explorer and my Campaigns tab.

Domain 1
Campaigns: Total links = 10,895,942 Open Site Explorer - Links =  224,000

Domain 2
Campaigns: Total links = 25,670,287
Open Site Explorer - Links =  157,000

Why would these be so different?

For reference, the "Historical Domain Analysis" shows these sites getting exponentially more links starting in February.  This is of concern to me.  I didn't do anything different in February to get so many more links (especially not in the millions).  If anything, I am hoping the "Campaigns" section is simply wrong about this.

Good call Francisco.  I checked GWT and forums are driving an insane amount of links.  I wonder why some tools capture this and some don't?

In any case, thanks for pointing me in the right direction!

That's a bit odd. Check your GWT links. Also make sure you are using the same domain: example.com vs www.example.com.

Millions of links? Check GWT and if there is something really suspicious, contact Google and tell them about what's happening. I don't know if you should tell them to devalue your links or what, but try to be as honest as you can.
