Page Authority Migration
-
PageA.html has a lot of links and has a Page Authority score. It is 301 redirected to PageB.html and eventually in OSE this also accumulates a Page Authority score. Is there a reason why PageA.html many months/years after continues to have a Page Authority when it is expected that its Authority signals have migrated (with any dampening effect etc) across to PageB.html.
-
Assuming PageA and PageB contain similar or duplicate content, you could use a canonical tag instead.
Google have noted canonical tags pass authority, as you're giving the search engine the direction that PageB is the best source of the content, instead of PageA.
Here's Webmaster Central post that discusses this: http://googlewebmastercentral.blogspot.com.au/2009/02/specify-your-canonical.html

While it is passing on the link equity there are most likely still links going back to the old URL. Unfortunately until backlinks for the new page start outpacing the old page or the older links become deprecated the old page will still outrank the previous one.
-
PageA.html's links still exist in the wild and haven't been updated to reflect the new page. When calculating the page authority, we still see all the links pointing to pagea and it calculates an authority for the page, although it has been permanently redirected to pageb.html.
Then the calculated authority is transfered through the 301 redirect. But, since all the external links exist, you won't see that PA vanish completely for pagea.
-
Well I have to agree with you on that one, 301 is an instruction that something is pemenantly moved so it would seem right if PageA.html's Page Authority lowered over time. I don't have a good answer why it don't.
-
I suppose because a 301 is an instruction that you've permenantly moved a resource and you are effectively asking for those ranking signals associated to be migrated across to the new location. If it is to be close to PageRank in its approach you would expect a migration of that link equity. In the case I'm looking at, one year on, the page that has been redirected almost has the same PA as the new page.
-
PageA.html does still have an Page Authority even if you 301-redirect it to PageB.html. PageB.html will get a boost from the redirect and it will strengthen PageB's Page Authority. Why would the Page Authority for PageA.html disapear just cause you redirect it?
However if that was the case (The Page Authority disapeared due to a redirect). That could do some damage if you redirected something temporary using 302-redirect or in other similar scenarios.

Domain Authority (DA) in Moz Pro changed only within the last 1-2 months?
Has anyone noticed that the Domain Authority (DA) as reported in Moz Pro has changed only within the last 1-2 months? We have screen shots showing plots of DA vs competitors w/ line graph 2 months ago starting in NOV 2017 which today starting JAN 2018 and comparing shows DA up to 50% different!

The change is seen both in the Links Overview and under the Spam Score sections still marked "NEW". Can Moz confirm that it's only recently within the last 2 months that in Moz Pro the NEW DA numbers have retroactively been updated even though the new Link Explorer has been publicly out since APR 30 from https://moz.com/community/q/moz-s-new-link-explorer-including-our-revamped-index-and-da-pa-scores-is-now-open-to-everyone? Look at the top green line starting ~12 months ago on both graphs, w/ old below 40 and new above 50. We've seen even greater differences for other tracked domains. Thanks! view0 -
Drop in Domain Authority across 20 sites
Hi I monitor and track 20-25 sites. I got a -1 in DA across the board this month. Has anyone else experienced this. It's possible my server/cms guys have made a global change. Has anyone at Moz or anyone in the community experienced this?

Top Pages in OSE
Hey, I'm using OSE to determine top pages for some domains. This works great for some sites, but I'm finding with a few sites only the home page comes up in the 'top pages' list - is this because the home page is the only one with a PA above one? Cheers

How Does Moz Assign Domain Authority?
When I use Site Explorer to test the following URL, http://jennathuening.results.net/site/index.php, it renders a domain authority of 47. (Clients site on real estate host) There are no page social metrics: no Facebook share no Facebook likes no Twitter tweets no Google+ plus 1's no "just discovered" in 60 days no one has made a post in 3 weeks much or most of the content is duplicate content across all affiliate sites inbound links - only one link - a 301 redirect http://jennathuening.results.net/ Images - 18 (Alt tags missing: 18) Created - 1998-10-15 Registered Org - REMAX RESULTS is associated with ~416 other domains Whois SEO Score 68% AND YET IT HAS A ROOT DOMAIN OF "47" and page authority of 33 More confusing, its page authority of 33 is at that top on blue background and then page 30 just listed below. When I use Site Explorer to test the following URL, http://www.homedestination.com, it renders a domain authority of 26. (Site personally owned and continually update with highly optimized fresh, relevant, quality content with grade "A" moz ranked pages and blog posts) 92 Facebook share 68 Facebook likes 13 Twitter tweets 420 Google+ plus 1's 2 "just discovered" in 60 days Images 25 (Alt tags missing: 0) inbound links - on 48 Root Domains Created - 2002-08-15 9 new indexed blog post so far in August / 19 new indexed blog post in July Whois SEO Score 100% AND YET IT HAS A ROOT DOMAIN OF "26" and page authority of 36 While I am sure there are many other factors as well; it still is hard to see where a "smaller guy" could ever be given an even opportunity to play in the same SEO arena. Could you help me understand better? I like to build a stronger marketing and optimization strategy as we are just beginning AdWord campaigns. | SEO Score | 100% |
