Inbound links not found in Moz Pro(though they exist)

[Yuji_m]

These sites have many inbound links but Moz Pro finds no such links. I also used SimilarWebPro Trial to confirm the existing of such links. (these sites have IP block so it requires an VPN to access with Japan IP)

Could anyone figure out why Moz can't find those links to those sites? Any tricks in place to hide those links from SeoMoz?

If I pay to upgrade SimilarWebPro but Id rather stay with SeoMoz Pro.

thanks in advance.

I think you answered your own question:  "these sites have IP block so it requires an VPN to access with Japan IP"

Moz Pro OSE is great, but if you are doing an in-depth inbound link analysis, it is a good idea to cross-reference with Ahrefs, Majestic SEO, and/or SEMrush as well. Usually these tools will show different numbers for unique domains and total backlinks. This is of course not taking into account the IP block you mentioned above.

Hey there! Tawny from Moz's Help Team here. 
I think the reason you're not able to find inbound links for those sites is just what you mentioned: you need a VPN to be able to access the sites with a Japan IP address. Our tools won't be able to get around that IP block, so we won't be able to find links pointing back to those sites. Sorry about that!
