Just 13 days ago on January 11th, we released the first Mozscape index for 2013. And today, we're launching the latest January Mozscape index - another two indexes in one month! Mozscape data has been refreshed across all our applications so you can see the latest data in Open Site Explorer, the Mozbar, PRO campaigns, and the Mozscape API.
This index finished up in record time, running smoothly on the high power cluster compute machines in AWS. Our Mozscape processing team (Doug, Martin, Brandon, and Stephen) has spent the past few months really cleaning up and optimizing the software that produces these indexes. Changes are slow going with this software - big data is big and changes are big! There is a lot of testing and optimizing that must be done before changes even make it into the production index, but these guys are dedicated to getting you index twice a month!
We're eagerly waiting for our first index to be released from our new colocation in Virginia - hopefully in the month of February. With some new configurations and master network tuning from our Tech Ops team, we currently have an index churning away, so far with promising performance!
Here are the metrics for this latest index:
And the following correlations with Google's US search results:
Since this index was kicked off January 14th, the latest crawl data is really fresh! There is just over 30 days of crawl data in this index, the majority being crawled in January, but some crawl data as old as mid-December. There was a significant increase in the number of subdomains crawled for this index compared to the our previous index. Further investigation revealed we found a fairly small increase of root domains that had a substantial number of new subdomains associated with them. Because they are such low authority, the increase won't have any impact on our metrics, but does significantly increase the number subdomains in this index.
We always love to hear your thoughts! And remember, if you're ever curious about when Mozscape is updating, you can check the calendar here. We also maintain a list of previous index updates with metrics here.
