Why is my domain authority (and page authority) plummeting?
-
In June our domain authority was at a 41. In July we were 38 and ever since then our domain authority is gradually getting worse and worse. We went from a 33 to a 29 in one week!
Possible explanations include:
- Maybe the SEO we hired (for a few months in late 2011) added our domain to some less-than-awesome directories
- The 301 redirects on our home page are hurting us somehow
- Duplicate content for URL's with different capitalization (IE: /pages/aboutus and /Pages/AboutUs)
Can someone please point me in the right direction? Which of the above possibilities would likely impact domain/page authority? Any other ideas as to why this might be happening? Any suggestions for improving our domain or page authority?
Thanks for the help!

Hi Micheal,
Sorry to hear about your Domain Authority dropping. But this isn't always as bad as it appears. First thing is to take a deep breath. Often times these things happen for perfectly innocent reasons, and often have no relation to your website in the real world.
The important questions are: Has your traffic dropped? How about a drop in rankings? This could indicated you've truly lost a good amount of your backlink profile, and might warrant further action.
Linkscape, and Open Site Explorer, are based on link metrics, so on-page factors like duplicate content generally don't make much of an impact. If your Domain Authority dropped it could mean a few things:
1. Domain Authority is a relative metric calculated fresh with each new index, meaning you shouldn't compare the score from one index to another. Instead, you should compare your score to your competitors and look for relative movement. That said, a drop from 41 to 29 is usually a sign of something bigger.
2. Mozscape and Open Site Explorer are updated about every 4 weeks. The metrics are entirely link-based, so downtime of your server won't effect the numbers.
Because we use a new index every few weeks, there's a natural fluctuation in the number of links we find. There are literally billions and billions of links on the web we have to crawl every month, calculate metrics for each one, and then package them into an index that makes sense.
Sometimes links will disappear or re-appear in the index. This is natural and usually minor, although a large jump or decrease in your Domain Authority can be scary - it doesn't mean your traffic or rankings will change. Mozscape may have trouble finding links on pages without a lot of links pointing to them, or links hidden under layers of navigation. For more, see this document:
http://www.seomoz.org/help/open-s...
3. Finally, it's possible you actually lost a portion of you backlink profile. Are you missing any important links that you are aware of? It's estimated that 80% of the web vanishes every year. If this is the case, you might want to use Google Analytics to find who was sending you traffic over the past couple of years, and verify those links are still around today. If you find links missing, perhaps you can take action, or be proactive in gaining new links.
Hope this information helps. Best of luck with your SEO!

Hi Michael
In short, it could be many reasons. A few things to consider:
Have you checked your Google Webmaster tool for clues?
Have you seen a drop in actual visitor traffic through GA?
Does the drop match the dates of some of the Google updates?
Have your competitor sites had the similar fate?
Are the red and yellow errors in your SEOMoz campaign reports increasing?
Checked Site Explorer for issues?
From of the three things you mention the first one maybe one to check - perhaps you are suggesting some iffy link building had taken place?
I assume you have had a capitilisation issue for ages so that in itself wont have caused a sudden drop.
Its more likely a series of things you need to fix so check back whats happened on the site in the past few months.
Finally, has it effected your bottom line? - sales / leads etc? That is what really matters.
Best of luck

Does Google considers the direct traffic on the pages with rel canonical tags?
Hi community, Let's say there is a duplicate page (A) pointing to original page (B) using rel canonical tag. Pagerank will be passed from Page A to B as the content is very similar and Google honours it hopefully. I wonder how Google treats the direct traffic on the duplicate Page A. We know that direct traffic is also an important ranking factor (correct me if I'm wrong). If the direct traffic is high on the duplicate page A, then how Google considers it? Will there be any score given to original page B? Thanks

SEO threats of moving from [.com.au] domain to [.com] domain for a 15yr old SAAS company.
Hey Guys. I work for a 15 yr old SAAS company which originally started with a country-specific [.com.au] domain and later got a [.com] domain as the business grew. The AU website has a DA:56 while the [.com] has as DA: 25. Now we are looking to have everything migrated to the [.com] domain. But, my concern is that we might lose the SEO value of the AU domain. I was wondering if anyone has any experience in this or recommend a case study on this topic. Thanks! Allan

Lost Wikipedia page and dropped heavily in rankings. How many of you aware of and experienced this?
Hi all, We lost of our Wikipedia page for 2nd time and we dropped in rankings 2nd time too. I got confused first time whether Wikipedia was the actual reason as we had couple of major changes in our website. But recently it's been clear that losing Wikipedia page is the culprit as we have no website changes around these days. How many of you aware of this and experienced this? Please share your views. Hope this info will help you. Thanks

Clicks are the ultimate factor to stick the page on position?
Hi all, We know many factors contribute to make a page rank at (top) position like somewhere in top 5 results. I have seen some of our pages suddenly spike to that positions and locked there. They been receiving clicks too. Will they be dropped if they don't get estimated clicks? I think many factors contribute to make a page rank higher but clicks are the one factor which makes the page consistently rank at its best position. What do you say? Thanks

Does the more number of ranking pages improve the website ranking?
Hi all, Let's say there is a website with 100 pages ad 95 pages are not ranking for any keywords; but the other 5 pages including homepage are ranking for some keywords. In this scenario, the 95% non-ranking pages does impact the other 5% pages rankings? Or every page holds their credibility in ranking irrespective of other pages in website? Thanks

What does it exactly means when Google brings the "brand name" to the beggining of the page title in search results when it was actually given at the end?
We see many times...page titles starts with "brand name: page for etc" where actually "brand name" has been given at the end and keywords at beginning. Why does Google make this change? I noticed this happens when similar title tags are used by multiple websites for high difficulty keywords. Thanks

Directories and Domain Authority
I read all the time about how directories have very little weight in SEO anymore, but in my field, a lot of our competitors are propped up by paying for "profiles" aka links from places like martindale-hubbard, superlawyers, findlaw, nolo, Avvo, etc (which are essentially directories IMO) yet all those sites have very high DAs of 80 and above. So, are links from these sites worth it? I know that's a vague questions, but if Moz's algo seems to rank them so highly, I'm guessing that's reasonably close to what google thinks as well...maybe? Thanks for any insight, Ruben

Do you think this page has been algorithmically penalised or is it just old?
Here is the page: http://www.designquotes.com.au/business-blog/top-10-australian-business-directories-in-2012/ It's fairly old, but when it was first written it hit #1 for "business directories". After a while it dropped but was receieving lots of traffic for long tail variations of "business directories Australia" As of the 4th of October (Penguin 2.1) it lost traffic and rankings entirely. I checked it's link profile and there isn't anything fishy: From Google Webmaster https://docs.google.com/spreadsheet/ccc?key=0AtwbT3wshHRsdEc1OWl4SFN0SDdiTkwzSmdGTFpZOFE&usp=sharing In fact, two links are entirely natural http://blog.businesszoom.com.au/2013/09/use-customer-reviews-to-improve-your-website-ranking/ http://dianajones.com.au/google-plus-local-equals-more-business-blog/ Yet when I search for a close match in title in Google AU, the article doesn't appear within even the first 4 pages. https://www.google.com.au/#q=top+10+Australian+Business+Directories&start=10 Is this simple because it's an old article? Should I re-write it, update the analysis and use a rel=canonical on the old article to the new?
