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.

Page Authority higher on my old (redirected) domain than new domain?
Hi everyone. I moved the domain my blog was on about 18 months ago, and it's ranking in Google never recovered. I've noticed in the 'Inbound Links' tool that my old domain (jamescrowley.co.uk) shows a page authority of 26, while my new domain (jamescrowley.net) shows a page authority of 15. Any idea why that would be? 301 redirects have been in place for the whole 18 months, so I'd have thought the authority would have been 'passed on' by now? Many thanks James

If I migrate to a new domain, does my Domain Authority score get migrated also?
For business reasons, I migrated my domain with a DA score of 85 to a new domain. After some time, the DA score on the new domain is only 45. My migration plan and redirects went smooth and all redirected with best practices in mind. I am still ranking well for almost all of the keywords where I've 301 redirected old URL to new. Any feedback welcome!
