Domain authority decrease after open site explorer update. Reasons?
-
Hi!
I just noticed a decrease on our domain authority and also the page authority of several of our pages on the SeoMoz toolbar. For instance, DA went from 34 to 29. I was scared and confused, so I went to check it on the opensite explorer and saw that it had been updated.
I want to ask you guys if the same happened with your metrics or is it just us. Because the strange thing about it is that we have been doing some good optimization work lately and also some linkbuilding, and actually our SERP’s have been improving in general, and some specific ones have been performing great.
Our website is http://www.inmonova.com as a reference.
Can anyone cast some light into this?

Hey guys!
Keri is right - we have done some updating with our crawler and this index represents the newest version - unfortunately with a few hiccups. People seem to be seeing two issues with this new index - link counts and domain authorities are going up or down considerably and there is an increase of "questionable" inbound links.
Both issues are due to the same root cause: our new crawler is built to be fresher, but it is going deeper into domains, and, unfortunately not visiting as many domains. Domains with a high MozRank are getting crawled deeper, but domains with middle to lower MozRanks are not getting crawled.
Our top priority now is to get the domain diversity back up to or better than that of our last update as was originally designed. It's fixable and we will be focusing all efforts on this.
Previous crawling worked by selecting a list of the top MozRank URLs (around 10B) and then crawling one page from each of them. Now we are crawling links as we discover them, and crawling high MozRank sites daily, weekly or monthly. The advantage of the new crawlers is we are crawling all the time and so we will have fresher data. As links are added, we are much more likely to discover these deeper links. The new crawl had 59B urls, a lot more than the previous 42B, however, more of these links are from the same domain.
The reason for the "questionable" links is due to the fact that the crawler is reaching deeper into the domains where there are more download links. We are currently looking into fixing this so these won't be counted as links. We'll let you know as soon as that issue is resolved!
We are really sorry for the inconvenience. Once we have this new crawler dialed it will provide much fresher and higher quality data!!
Thanks,
Carin

Hey! Thanks a lot. I was a bit worried because the timing was just not very lucky for us.
There had been almost no SEO work, at leas no linkbuilding, for 2 years and we only started 2 months ago, so causality was making me wonder if we had been doing something wrong.
Your answers make me feel better. And yes, it's true that competitors have also gone through changes. Some have improved though (grrrrrrr.....).
Looking forward to the engineer's explanations!

Hi! Don't panic! This is part of the OSE algorithm update. The OSE engineers will be over here in the next few days to give some more explanation here, but wanted to let you know now that it isn't your website that had a big change.

We noticed the same decrease on three of our websites as well, and some of the competitors we track. One of our websites also went dramatically up (with many new questionable links). I believe this latest update of the link graph had some major changes that altered the domain authorities on a lot of websites. These numbers are all relative to everyone else, so hopefully this isn't an accurate reflection of how our websites are performing.
Good luck! Happy optimizing
Andrew

Witch domain to use the highest authority and backlinks or the new one?
Hello I have 2 domain names to the same website as described: domain.net is redirecting to domain.com 301. domain.net age = 16 years domain.com age = 18 years domain.net was in use before the 301 redirects for many years, and it have a better moz authourity(55) from domain.com(45). also have a better count of linking domains(3.2K backlinks) backlinks from domain.com(1.2K backlinks). all data is from Moz pro. the question was what to use for my website for more SERP traffic? Is using .net domain better? or make them both work without 301 redirect with a canonical meta tag? if yes to witch domain best to point this meta? Thanks

Page authority questions?
I've been analyzing some IT communities ...in order to check how relevant is the page authority vs PageRank. I found one main site which is organized by "communities'..and every community is a sub-domain. The root domain has an authority of 90/100 which it should be great......so the sub-domains "inherit" part of this authority.... Until here everything seems to be perfect. However, I went deeper and I picked one of these communities. Analyzing the "Linking Root Domain" I discovered it only has only 5 root domains pointing to its home page. Those 5 Root Domains have generated more than 134k links. That doesn't seem to be "natural". Checking those 5 Root Domains I discovered that they have been registered by the same Root Domain site. Ex: Main domain: Domain.com Community1.domain.com Community2.domain.com.... Linking Root Domains: DomainXY.com DomainABC.com DomainRST.com DomainFGH.com DomainOPQ.com It seems to me that it is easy to cheat the authority domain score. Just creating others sites developing the same topic and generating back links to your main domain

How is domain authority related to country top level domains?
I've noticed that for some country top level domains (tld) the domain authority returned by open site explorer is based on the domain that has been registered within the tld. For example, domainname.co.uk provides a domain authority specific to the domain. However, for some other country top level domains, this does not appear to be the case. Examples I have found include: domainname.co.nr domainname.co.pt domainname.co.ee For these top level domains the domain authority seems to be the same for every domainname, seemingly implying the domain authority is for the top level domain itself rather than for the domain. Is this a common situation for many country top level domains, so that what I see going in here is the tip of a large iceberg, or does this situation just apply to a very isolated set of country top level domains?

CSV export of Open Site Explorer is incomplete.
I exported my back links report from the Open Site Explorer toolbar as a CSV but the file it showed was only about 400 urls. The tool bar is listing over 1,200 links, so at first I thought maybe it was only exporting one link for each unique domain, but it only lists 200 or so unique domains linking to my site. I know it will only export 10,000 urls, but obviously I'm significantly below this level. Here is a link to a competitors site which is having the same issue.

Why is open site explorer not showing the top links that if found previously.
In previous months ago open site explorer listed many other sites linking to mine. I have checked those sites and they are still linking to my site. Why doesn't open site explorer list them?

Potential site architecture problem.
We are experiencing a problem in which category pages do not appear to be passing Page Authority to subcategory pages. See the example below: Home page has PA of 47 http://www.minespress.com/ The next level category page down has a PA of 34 http://www.minespress.com/category/apparel The next sub category down has PA of 1, and shows no links at all in spite of the fact that we got to it from a category link http://www.minespress.com/category/golf-shirts The page in question is crawlable, is indexed and has nothing that we can see that would be prevent it from showing Page Authority and a link profile using your tools. Do we have a site architecture problem?
