Open Site Explorer Data

[Aviatech]

Good afternoon SEOmoz,

I first want to congratulate with you for the amazing new look and new features of Open Site Explorer, it's an amazing and valuable tool that I use every day and that has helped me build tons of links for my clients.

I have been keeping track of the OPE data on a monthly base and I just noticed something strange.

In May 2011, OSE was showing that my client's website had 12,624 links, in July 2011 the website had 14,157 links and today I just ran a new report that showed just 6,401 links.

I don't want to believe that in 2 months we lost half of the links, so I was wondering if you guys can give me more insights about this data. 
Did SEOMoz change the way they measure the number of links? Or is this just a bug or issue they are having with the new version of OSE?

Thanks!

Hi Dwight,

The crawl did change a bit. Check out this thread http://www.seomoz.org/q/domain-authority-decrease-after-open-site-explorer-update-reasons for some more information from the OSE people.
