First Mozscape index of the year is live
-
I'm happy to announce, the first index of the year is out. We did have a smaller count of subdomains, but correlations are generally up and coverage of what's in Google looks better, too. We're giving that one a high five!
We've (hopefully) removed a lot of foreign and spam subdomains, which you might see reflected in your spam links section. (another woot!)
Here are some details about this index release:
- 145,549,223,632 (145 billion) URLs
- 1,356,731,650 (1 billion) subdomains
- 200,255,095 (200 million) root domains
- 1,165,625,349,576 (1.1 Trillion) links
- Followed vs nofollowed links
- 3.17% of all links found were nofollowed
- 63.49% of nofollowed links are internal
- 36.51% are external
- Rel canonical: 26.50% of all pages employ the rel=canonical tag
- The average page has 89 links on it
- 72 internal links on average
- 17 external links on average
Thanks!

Real case... almost 10 years ago SEO manager in some company was flying to their HQ just to explain why their PR was dropped from 6 to 5. C-level execs wasn't happy about that.
Now fun part - impressions, CTR and visits was increased during that update.

Great to post this at the top of the Q&A - noticed the first questions appearing today - probably many more to follow (hopefully fellow Moz'ers will read this post before posting the question).

Sitemaps and Indexed Pages
Hi guys, I created an XML sitemap and submitted it for my client last month. Now the developer of the site has also been messing around with a few things. I've noticed on my Moz site crawl that indexed pages have dropped significantly. Before I put my foot in it, I need to figure out if submitting the sitemap has caused this.. can a sitemap reduce the pages indexed? Thanks David.

Mozscape Index update frequency problems?
I'm new to Moz, only a member for a couple months now. But I already rely heavily on the mozscape index data for link building, as I'm sure many people do. I've been waiting for the latest update (due today after delay), but am not seeing any mention of the data yet - does it normally get added later in the day? I'm not that impatient that I can't wait until later today or tomorrow for this index update, but what I am curious about is whether Moz is struggling to keep up, and if updates will continue to get more and more rare? For example, in 2013 I count 28 index updates. In 2014 that number dropped to 14 updates (50% drop). In 2015, there was only 8 (another 43% drop), and so far this year (until the March 2nd update is posted) there has only been 1. This isn't just a complaint about updates, I'm hoping to get input from some of the more experienced Moz customers to better understand (with the exception of the catastrophic drive failure) the challenges that Moz is facing and what the future may hold for update frequency.

January’s Mozscape Index Release Date has Been Pushed Back to Jan. 29th
With a new year brings new challenges. Unfortunately for all of us, one of those challenges manifested itself as a hardware issue within one of the Mozscape disc drives. Our team’s attempts to recover the data from the faulty drive only lead to finding corrupted files within the Index. Due to this issue we had to push the January Mozscape Index release date back to the 29<sup>th</sup>. This is not at all how we anticipated starting 2016, however hardware failures like this are an occasional reality and are also not something we see being a repeated hurdle moving forward. Our Big Data team has the new index processing and everything is looking great for the January 29<sup>th</sup> update. We never enjoy delivering bad news to our faithful community and are doing everything in our power to lessen these occurrences. Reach out with any questions or concerns.

September's Mozscape Update Broke; We're Building a New Index
Hey gang, I hate to write to you all again with more bad news, but such is life. Our big data team produced an index this week but, upon analysis, found that our crawlers had encountered a massive number of non-200 URLs, which meant this index was not only smaller, but also weirdly biased. PA and DA scores were way off, coverage of the right URLs went haywire, and our metrics that we use to gauge quality told us this index simply was not good enough to launch. Thus, we're in the process of rebuilding an index as fast as possible, but this takes, at minimum 19-20 days, and may take as long as 30 days. This sucks. There's no excuse. We need to do better and we owe all of you and all of the folks who use Mozscape better, more reliable updates. I'm embarassed and so is the team. We all want to deliver the best product, but continue to find problems we didn't account for, and have to go back and build systems in our software to look for them. In the spirit of transparency (not as an excuse), the problem appears to be a large number of new subdomains that found their way into our crawlers and exposed us to issues fetching robots.txt files that timed out and stalled our crawlers. In addition, some new portions of the link graph we crawled exposed us to websites/pages that we need to find ways to exclude, as these abuse our metrics for prioritizing crawls (aka PageRank, much like Google, but they're obviously much more sophisticated and experienced with this) and bias us to junky stuff which keeps us from getting to the good stuff we need. We have dozens of ideas to fix this, and we've managed to fix problems like this in the past (prior issues like .cn domains overwhelming our index, link wheels and webspam holes, etc plagued us and have been addressed, but every couple indices it seems we face a new challenge like this). Our biggest issue is one of monitoring and processing times. We don't see what's in a web index until it's finished processing, which means we don't know if we're building a good index until it's done. It's a lot of work to re-build the processing system so there can be visibility at checkpoints, but that appears to be necessary right now. Unfortunately, it takes time away from building the new, realtime version of our index (which is what we really want to finish and launch!). Such is the frustration of trying to tweak an old system while simultaneously working on a new, better one. Tradeoffs have to be made. For now, we're prioritizing fixing the old Mozscape system, getting a new index out as soon as possible, and then working to improve visibility and our crawl rules. I'm happy to answer any and all questions, and you have my deep, regretful apologies for once again letting you down. We will continue to do everything in our power to improve and fix these ongoing problems.

In lue of the canceled Moz Index update
Hey Moz, Overall we love your product and are using it daily to help us grow, part of that has been to rely on the Moz Index for DA and PA as well as places where we are doing positive linking through genuine partnerships and reviews of clients. We were really excited to see any the results for this month as we have been partner linked from lots of high reputation sites and google seems to agree as our rankings are moving up weekly. The question from our marketing team is, since a significant part of Moz will not be available to us this month, will there be any compensation handed out to the paying community. PS: I am an engineer and I know how you have probably lost a very large set of data which cant simply be re-crawled over night but Moz Pro is not a cheap product and we do expect it to work.

August 3rd Mozscape Index Update (our largest index, but nearly a monthly late)
Update 5:27pm 8/4 - the data in Open Site Explorer is up-to-date, as is the API and Mozbar. Moz Analytics campaigns are currently loading in the new data, and all campaigns should be fully up-to-date by 4-10pm tomorrow (8/5). However, your campaign may have the new data much earlier as it depends on where that campaign falls in the update ordering. Hey gang, I wanted to provide some transparency into the latest index update, as well as give some information about our plans going forward with future indices. The Good News: This index, now that it's delivered, is pretty impressive. Mozscape's August index is 407 Billion URLs in size, nearly 100 Billion (~25%) bigger than our last record index size. We indexed 2.18 trillion links for the first time ever (prior record was 1.54 trillion). Correlations for Page Authority have gone up from 0.319 to 0.333 in the latest index, suggesting that we're getting a slightly more accurate representation of Google's use of links in rankings from this data (DA correlations remain constant at 0.185) Our hit ratio for URLs in Google's SERPs has gone up considerably, from 69.97% in our previous index to 78.66% in the August update. This indicates we are crawling and indexing more of what Google shows in the search results (a good benchmark for us). Note that a large portion of what's missing will be things published in the last 30-60 days while we were processing the index (after crawling had stopped). The Bad News: August's index was late by ~25 days. We know that reliable, consistent, on-time Mozscape updates are critically important to everyone who uses Moz's products. We've been working hard for years to get these to a better place, but have struggled mightily. Our latest string of failures was completely new to the team - a bunch of problems and issues we've never seen before (some due to the index size, but many due to odd things like a massive group of what appear to be spam domains using the Palau TLD extension clogging up crawl/processing, large chunks of pages we crawled with 10s of thousands of links which slow down the MozRank calculations, etc). While there's no excuse for delays, and we don't want to pass these off as such, we do want to be transparent about why we were so late. Our future plans include scaling back the index sizes a bit, dealing with the issues around spam domains, large link-list pages, some of the odd patterns we see in .pl and .cn domains, and taking one extra person from the Big Data team off of work on the new index system (which will be much larger and real-time rather than updated every 30 days) to help with Mozscape indices. We believe these efforts, and the new monitoring systems we've got will help us get better at producing high quality, consistent indices. Question everyone always asks: Why did my PA/DA change?! There are tons of reasons why these can change, and they don't necessarily mean anything bad about your site, your SEO efforts, or whether your links are helping you rank. PA and DA are predictive, correlated metrics that say nothing about how you're actually performing. They merely map better than most metrics to Google's global rankings across large SERP sets (but not necessarily your SERPs, which is what you should care about). That said, here's some of the reasons PA/DA do shift: The domains/pages with the highest PA/DA scores gain even faster than most of the domains below them, making it harder each index to get higher scores (since PA/DA are on a logarithmic scale, this is smoothed out somewhat - it would be much worse on a conventional scale, e.g. Facebook.com 100, everyone else 0.0003). Google's ranking algorithm introduces new elements, changes, modifies what they care about, etc. Moz crawls a set of the web that does or doesn't include the pages that are more likely to point to a given domain than another. Although our crawl tends to be representative, if you've got lots of links from deep pages on less popular domains in a part of the web far from the mainstream, we may not consistently crawl those well (or, we could overcrawl your sector because it recently received powerful links from the center of the web). My advice, as always, is to use PA/DA as relative scores. If your scores are falling, but your competitors' are falling more, that's not a bad thing. If your scores are rising, but your competitors' are rising faster, they're probably gaining ground on you. And, if you're talking about score changes in the 1-4 points range, that's not necessarily anything but noise. PA/DA scores often shift 1-4 points up or down in a new index so don't sweat it! Let me know if you've got more questions and I'll do my best to answer. You can also refer to the API update page here: https://mza.bundledseo.com/products/api/updates
