It has been an amazing month at Moz, and for the first time, we have served up three indexes in one month – holy fresh data, Batman! This index is also our second index release from our Virginia data center.

As we’ve become so regular with our index releases, it seems that a blog post announcing each release may not be the best way to inform our customers on releases as they happen. This will be the last index update announced on the blog, but index release readers, have no fear! There’s a new, more digestible way to get all of the information about the index updates you know and love.

Going forward, we invite you subscribe to the Mozscape RSS feed found on the lower right-hand corner of the http://moz.com/products/api/updates page so that you will know when we have released a new index. Simply click on the RSS feed icon… 

…and you’ll be directed to our Feedburner Mozscape updates page. This page makes it easy to enter your information to subscribe to our index updates: 

Just enter your email address, choose your reader, and let the Mozscape index data flow in! 

As our index releases continue to become more frequent, you can expect the number of updates received through the RSS to mount. We hope you enjoy this new way to consume fresh update info as much as we do.

Here are the metrics for this index:

• 85,870,573,626 (86 billion) URLs
•   5,524,096,501 (5.5 billion) Subdomains
• 155,443,706 (155 million) Root Domains
• 902,845,046,889  (903 billion) Links
• Followed vs. Nofollowed
•   2.17 % of all links found were nofollowed
• 57.32 % of nofollowed links are internal
• 42.68 % are external
• Rel Canonical –  14.44 % of all pages now employ a rel=canonical tag
• The average page has 79 links on it
•  67.836 internal links on average
•  11.13 external links on average

And the correlations with Google’s US search results:

• Page Authority – 0.36
• Domain Authority – 0.19
• MozRank – 0.24
• Linking Root Domains – 0.30
