Domain Authority Historic Differences?
-
Moz Team,
We are again seeing shifts on how we report on Domain Authority. When Moz moved from OSE to LE, domain authority scores changed (which is fine because our direct competitors in LE also saw similar changes). The problem is it looks like domain authority trends have re-calibrated to show a long term decline instead of a long term increase, which changes the narrative entirely. Please see IMGUR link. Is this a temporary issue, or has Moz again changed the scale in which DA is measured? Is anyone else seeing disparities in their data?
Thanks All!

Thanks Meghan, I appreciate the feedback and I understand the need to adjust, but using domain authority as a reliable KPI is becoming increasingly difficult, particularly when the historic data between the 2 models contradict one another. These are changes we have to report out on to clients, can we expect additional roll-outs in the near future?
Thanks as always!

Hi Paul!
Thanks so much for the question and sorry for the confusion here.
We did make an adjustment on our end which may cause slight variations in the current and historic DA/PA you're seeing in the Link Explorer tool. This adjustment was made to account for the rapid growth of our index over the last six months in order to stabilize distribution of scores over time.
One of our engineers posted a thread about this yesterday which you can see here. In this post, Ian talks about the recent update and why we made it- hopefully it will help shed some more light on this for you.
I hope this helps! If you have any further questions, please feel free to email us at help@moz.com and we'll be sure to get those answered.

Unsolved Google results linking domains
When I check the linking domains of a root domain, a lot of Google results from other countries appear. Does this mean all of these domains are linking to my root domain? Can anybody explain this and tell me if this can be seen as spam or not? linking-domain-moz.png

How do I find http backlinks to my domain?
Hi, We spotted a number of sites linking to us from http sites, not https sites. How can I use backlink tools to find just those from http sites? Right now I'm looking at exporting a spreadsheet with 3.3 million entries and filtering - and there's not one person here who wants to do that! Thanks in advance.

Page Authority different between Moz Open Site Explorer and On Page analyser
I have a client who has an old URL with 3 linking root domains and 4 links, with a PA of 24. This is on the open site explorer. There is a 301 redirect in place to direct this old url to the new url. When he uses the Moz bar on page, it shows that he has a PA of only 1 with no LRDs or inbound links? Can anyone please explain why this is happening and if this could affect further page links across his site? It would be appreciated. Kind regards

Do other sites linking to my page with a low domain authority affect my rankings?
Hello, my page authority 30, I see other page with an authority of 21 for example linking to us. Is this good or bad, does this affect our ranking? A lot of these don't have anchor text, I'm guessing we should reach out to these webmaster to include anchor text with the keywords we want to drive traffic to this page or make as descriptive as possible? Thanks! Laura

Permanent 301 - Domain Authority
Hi, we created a new website which we also gave a new url.
Link Explorer | | DIGIHOUSE
We made a permanent 301 for the complete domain. www.digihouse.at -> www.digihouse-werbeagentur.at Google checked that and we rank minimum as good as with the old domain.
But in MOZ Tools the Domain Authority is very bad now.
So i think the 301 influences Google but not the Moz Tools?
The Domain Authority will not be inherited in Moz Tools? thxChris0 -

Domain Authority Trending Down?
Hi All, Can anyone (preferably a Moz representative) explain why Domain Authority has been trending down on multiple domains? I suspect there is a new index in place? And / Or algo changes? This is making life very difficult for us as our client www.cleanawater.com.au has been working very hard to implement only the whitest of white SEO models.
