Big drop in Domain Authority on 17 Nov 2015
-
Hello,
My domain authority dropped on 17 Nov 2015
Domain name is: http://www.proprofs.com/ drop from 74 to 68
Also on another domain : http://www.marriage.com/. Drop from 38 to 34.
Very much surprised by this big drop?
Would appreciate everyone's feedback?
Thanks

Hi there.
It's not me suggesting it, it's Rand Fishkin (founder of MOZ) saying it - check the link I refer to in my answer. Second paragraph. (It's quoted in my answer as well)

Can anyone at moz confirm this?
Our site and its competitors all dropped in DA. Ours went from 57 to 48, which is no small change.
I can't really let this drop without a proper explanation, if it is as Dimitri suggested a recalibrating of the scale from 0-100 then someone from Moz should confirm this.

Hi, Greg.
I still think that the explanation roots in the relativity idea I have quoted above. Also I linked to original post by Rand, so, check it out - you might find all the answers

I saw a similar effect across campaigns. 9 out of 10 dropped, just last week. Whenever I see that across a number of campaigns, I assume it is one of two things:
-
A simple algorithm tweak for the DA calculation.
-
Google is tuning their main algorithm, it caused real DA impact to sites, and creates a cascading effect across the DA ranks.
The last time I saw this effect was late april early may of this year, right as google was starting to push out the update that they eventually rolled back. A few months later, I saw the DA ranks all go up to where they were before, again, across 9 campaigns.
I guess the question is, is Google moving again? Or is Moz simply tuning?
Thanks,
Greg

Thanks for a great explanation,
Checking competitors trends was a great addition. We saw a drop in DA and I was at first concerned,but then noticed the same in competitors. Thanks Dmitrii

Hi there.
Please refer to this topic by Rand: https://moz.com/community/q/da-pa-fluctuations-how-to-interpret-apply-understand-these-ml-based-scores
Read #2:
You've earned more links, but the highest authority sites have grown their link profile even more
Since Domain and Page Authority are on a 100-page scale, the very top of that represents the most link-rich sites and pages, and nearly every index, it's harder and harder to get these high scores and sites, on average, that aren't growing their link profiles substantively will see PA/DA drops. This is because of the scaling process - if Facebook.com (currently with a DA of 100) grows its link profile massively, that becomes the new DA 100, and it will be harder for other sites that aren't growing quality links as fast to get from 99 to 100 or even from 89 to 90. This is true across the scale of DA/PA, and makes it critical to measure a site's DA and a page's PA against the competition, not just trended against itself. You could earn loads of great links, and still see a DA drop due to these scaling types of features. Always compare against similar sites and pages to get the best sense of relative performance, since DA/PA are relative, not absolute scores.Basically, DA/PA is relative metric, it's relative to 100 DA websites, so, if let's say facebook got +million links, and you got only +10, then relatively to FB your website DA will drop. That's why so many websites' DAs have dropped after last crawl.
To see how good/bad your DA changed, compare to your competitors.
Hope this helps.

HI Sameer
I wouldnt worry too much since i think this is much more to do with MOz recent Index update.
If i look at my 'Manage Campaigns' page where i see a list of all my campaigns currently running (10 campaigns), 9 out of the 10 DA has dropped by a similar percentage.
Hence this IMO is a Moz crawl drop in DA rather than real world drop in site authority
Would be good to get a response from a Mozzer too just to confirm ??
All Best
Dan

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?

Which domain to use? nichecity.es , nichecity.net or niche.cat ?
Hi, I must warm you that I am lame as hell in this SEO buisness. I just kinda made (not finished yet) my first wordpress site for a female art therapist friend of mine based in Barcelona, Spain who wants to have an internet presence and get some consulting clients. I made a little research through adwords keyword tool and found out "arteterapia barcelona" (medium competence, 390 local searches) is a reasonable niche with medium competence (0,62) but the other keywords are just for people trying to know what art therapy is or try to become art therapist themselves (cursos -courses-, master, etc). Then there is "arte terapia barcelona" which gives roughly the same results (high competence -0,72-, 390 local searches). She is not ready yet to offer courses and anyway I thought I would focus on organic positioning her with keywords "arteterapia barcelona" and maybe "arte terapia barcelona" but do a multilngual website as it is an added asset for customers. My guess is people who look for an arttherapist in Barcelona use these keywords: either "arteterapia barcelona" or "arte terapia barcelona" (in english "arttherapy barcelona") as "arteterapeuta barcelona" (in english, "art therapist barecelona") gives NO RESULTS whatsoever ¿??¿? So I (maybe a mistake to start with) got some free webspace from 000webhost.com and the free domain arteterapia.hostoi.com , installed wordpress and built a website from scratch with a variation of twenty eleven wordpress theme. When I realized arteterapia.cat was still available I kinda panicked and bought it right away (maybe a mistake). But as I want to organically position arteterapia AND barcelona I bought arteterapiabarcelona.es and .net (com is not available). The thing is, I don't know which one to use or them all. Frankly, I don't know where to start. Should I try to position each page separately? Or just alternate using "arte terapia" and "arteterapia" throughout the site? Should my priority now be to choose one of these (probably arteterapiabarcelona.es) and try to get some backlinks or use them all? Are.cat domains as powerful for people doing searches in catalonia region as .es for people doing searches in spain? Should she use Adsense? Any good tutorial on how to calculate the cost of that¿ Sorry again for the probably lame questions. And thanks. I do appreciate your help A LOT. Miguel

Domain redirection www or without
when i start campain for the first time it says " "Roger has detected a problem: We have detected that the domain www.xxxxxxtour.com and the domain xxxxxxtour.****.com both respond to web requests and do not redirect. Having two "twin" domains that both resolve forces them to battle for SERP positions, making your SEO efforts less effective. We suggest redirecting one, then entering the other here." How to resolve this and how can i redirect xxxxxxtour..com to www.xxxxxxtour.com ? Thank you

Impact of 301-redirected domains on OSE Metrics
When looking at the OSE metrics (DA, PA, Number Linking RDs etc.) is it purely based on OSEs evaluation of the specific domain or will it take into account links that have been 301-redirected to the domain?

Domain Name Portfolio Management?
I am looking for some software, or an excel spreadsheet, or some way to manage 50-100 domain names. Maybe something a reseller of domain names would use? Something that keeps record of different whois information for different domain names, tracks IPs, nameservers, FTP logins, etc... I think excel would be best for this if there was a way to have the expiration date pulled so I dont forget to renew a domain name by mistake, and so I can easily keep track of them all in one place. I have seen a couple software programs out there for this, but none really meet all the needs I have. I also looked into some kinda database software with a nice GUI (MS Access, or FileMakerPro) but I dont know them software well. Any Ideas?
