Domain authority drop
-
Hi SEOmoz gurus,
The last 2 months I am seeing a drop in the Domain authority for some of my clients.
- Some of them are old sites.
- Some are new (less than 6 months old)
For the old sites I thought the reason for the drop might be caused by discounting the value of low quality backlinks.
But this cannot be the case for the new sites - they have high quality backlinks from newspapers and I can't make any sense of the drop.
Has anyone else experienced the same issue?
Might this be caused by a change in SEOmoz algorithm?
Thanks!

When you say "drop", what kind of movement are we talking about? Could you give a before/after example without naming the site?
The DA/PA algorithm is based on machine learning, so even if the link-graph remained static, it is recalibrated from time to time. Of course, on top of that, the link-graph never stays static. If you're talking about something like 62->60, it probably wouldn't mean much at all. If you're talking about 60->40 and consistently large-scale drops, that would more likely indicate problems with your link-building strategy across all of the sites.

Hi Kyle,
Thanks for your reply.
I cannot check historical data for the DA for my competitors and since I am not keeping track of them, I cannot tell if they've dropped or not.
I was wondering if someone from the SEOmoz core team can enlighten us about an algorithm change..

Hello,
This can happen for many reasons. But going off the information you have provided you may want to check the links your newer sites have from newspapers as some UK publications have been hit recently by a Google penalty: http://www.davidnaylor.co.uk/interflora-what-really-happened.html
Before you get carried away though, check your verticals and compare your sites with their competitors to see if they have experienced any changes.

Moz Domain Authority 27
Hi there, I have been reading up about Domain Authority being important to rank though I have a question about it. When trying a few google searches and using a tool to see the Moz Domain Authority i notice the following. I won't mention sites or keywords, happy to send them via private message if required. A site ranks 1st position for most keywords including the main keyword that related to their industry, a highly competitive keyword. Their Moz Domain Authority 27, Est. Visits: 265,000, Pinterest shares 72, Facebook shares 191 and unique domains that point to it are 55. Yet when I look at another site, optimising for the same keyword, Moz Domain Authority 50, Est. Visits: 60,000, Pinterest shares 35000, Facebook shares 20000 and unique domains that point to it are 521. I would have thought that the second site ranks 1st for the keyword and the first one mentioned which is in 1st position I would have expected to be on page two or three. as I scroll down the first page for the term, all sites except for one have higher DA, visits, shares and so on. If a high PA is required can someone help me to understand the above example? Whn a low PA site ranks much better for a primary keyword than all other sites that have a higher PA than it?

Why do the competitive link analysis numbers not match the domain analysis?
There is only one area that our competitor out ranks us and that is in the total links on the root domain. But when i go to competitive link analysis we have more links then they do. Any ideas?

Campaign Domain "change" (www. vs no www.)
Hello, I'm tracking a domain (with www.thespin.be) since months. Last week we changed things related to domain & server and now SEOmoz has 0 pages crawled. I think that's because now my main domain is without www. (thespin.be). How can I modify my campaign to reflect this "change" (that's not really a new domain..) to avoid losing all my campaign history ? Also, on Google Webmaster Tools it's like I have 2 different sites (one with www. and another without), although I've defined my favorite domain (without www.) months ago.. Google won't update its index. And I have this problem on several other sites.. Thank you very much for giving me a feedback. Regards Jean-Louis

One Follow Link from each subdomain/domain best for SEO?
Hi there, we have a lot of customers linking to our homepage from a subdomain of our domain or from an external domain. From SEO point of view is it best that they all only have one DoFollow Link and the rest of the links are NoFollow? Or does this have no matter at all? The problem is that we have like 900.000 links but only from round about 1000 different root domains. If we put like half of the links on NoFollow our ratio of links/ different root domains gets better. Thanks for answering! Sebastian

How do I fix a duplicate content error with a top level domain?
Hi, I'm getting a duplicate content error from the SEOmoz crawler due to an issue with trailing slashes. It's showing www.milengo.com and www.milengo.com/ as having duplicate page titles. However I'm pretty sure this has been fixed in the .htaccess file since if you type in the domain with a trailing slash it automatically redirects to the domain without a trailing slash, so this shouldn't be an issue. I'm stuck here. Any ideas? Thanks. Rob

Question about a dramatic decrease in domain authority.
My personal website http://Bsalva.com has started to drop in both page authority and domain authority. This seems to be largely due to open site explorer not picking up all of my inbound links. Right now it says I only have one linking root domain, but I know this to be crap. I have quite a few followed links from well trusted and reputable sites. My page rank typically bounces between a 5 and 6. I should also have hundreds of inbound links. The other sites In my campaign monitor haven't taken such a hit so I'm starting to get a little worried. Does anyone know what might cause incoming links to not me recognized? they were just fine last month, and I can go find them on the web as we speak.

Which would you chose? Link on PA56 with 88 OBL's and 80 IBL's or a link on a PA75 with 225 OBL's & 40 IBL (Same Domain)
Which would you chose? Link on PA56 with 88 OBL's and 80 IBL's or a link on a PA75 with 225 OBL's & 40 IBL (Same Domain) Pretty self explanatory. I want to know what metrics SEOMozzers rely on most. If you are not an expert at evaluating links for large scale development please don't muddy the waters on this question with a thin and vague answer.
