Why My Domain Authority Dropped
-
See my relevant answer to an older, similar question here:
https://moz.com/community/q/why-did-my-site-s-da-just-drop-by-50
"Keep in mind that PageRank (which is used by Google to weight the popularity and authority of web pages, yes it's still true even after the little toolbars got deleted) does not read, utilise or rely upon Moz's DA metric in any way shape or form. DA is a 'shadow metric'. Since Google took away our view of the simplified PageRank algorithm (TBPR - ToolBar PageRank, which is dead) people working in SEO needed a new metric to evaluate the quality and ranking potential of web pages
Moz stepped in to supply this (in the form of PA / DA) but Google still use PageRank (they just don't show it to us any more). Whilst Moz's PA/DA metrics are a good 'indicator' of success, Google isn't using them (at all) and so they do not directly affect your rankings"
Only someone from Moz can confirm why your DA dropped, but it may have dropped for a reason that wouldn't impact or effect Google rankings in the slightest (so don't panic yet!)

No, sir, i didn't make any changes

Hello Rishi,
Have you made any changes to the site?
DA is a concept proprietary to Moz, it was recently recalibrated which may explain the drop - https://moz.com/domain-authority-2.0

What can be done to regain backlinks dropped (20%) in May 4th Core update?
We have seen two large drops in backlinks (10% drop twice) after the May 4th Google Core update. What can be done to "get them back"? And what is the best way to identify them. We are talking tens of thousands. Any help or insights are greatly appreciated!

Requesting udpate's from old domain to new domain
Hey guys, We had a domain change three years ago now which was redirected. Many of the old domains have not been updated to the new domain. The redirect is in place. I'm just wondering if there would it be a worthwhile exercise to reach out to sites to request an update of the URL link from an SEO perspective? Many thanks Rob

Redirects affect on page and domain authority
Hi - excuse me if this is stupid question but I'm rather new to this. Currently the PA for the home page is 16 and the DA 28 and I have some concerns that my efforts are being diluted. When I use OSE on www.sassandgrace.co.uk I get different link results to sassandgrace.co.uk but there is a redirect in place to sassandgrace.co.uk and cannot run a crawl report, for example, on www.sassandgrace.co.uk. The PA and DA are identical for each but the number of links different With a smallish number of links pointing to each but with a redirect in place, am I losing some of the effect or is having the redirect in place giving me all the credit for links to both addresses? Thanks

How do we optimise links from a parent company to a subsidiary on different domains
So we are the agent for an industrial company. They don't have a great website (well its pretty but doesn't rank) and have 5 product pages with a variety of products on each. We've taken those products and turned them into 50 pages with good on page optimisation. Now they've just agreed to give us a link on each page and I'm trying to figure out what the best text and link will be. As far as I can see there are three options Visit our agent for X region - sending to the home page If you are from X region you can request a sample of product group from our agent - sending to home page and product category page on our site If you are looking for X, Y, Z or P, Q, R in this region contact our agent there. - sending to home page and individual product pages The aim of this is to boost my page authority as 98% of the top 10 in SERPS have pages with zero authority and rely on the on page optimization and DA. Is this the best approach or are there other better ways of approaching the problem. It's worth noting that there is a total separation of control and ownership of the websites. I'm also starting to work with them to improve their on page optimisation and get links from their parent company to increase link juice

Can I 301 re-direct a page to regain the authority from a penguin penalized page
I built way too many anchor text links to an internal page and was penalized for the associated keyword. However, I do rank on that page for less significant keywords that I didn't build anchor text links for, though not super high. Subsequently, I've found that the sites that rank highly for the keyword that I was looking to rank for are high domain authority with almost no links built to those pages. Can I 301 re-direct that URL to my homepage, where I'm not trying to rank for that term, to make use of that authority of the links I've built to that page and start over on the page that I was hit by penguin on? This appears to make sense to me as my pages that have been hit are specifically for the terms that I have gone overboard on anchor text links. Terms that I haven't built too many anchor text links to still rank on those pages.

What tools/techniques you use to check if a domain has been penalized?
If we think to buy expired or otherwise dropped domains, what tools or techniques you would recommend to check if there has bad SEO history? We could of course, check with Google itself if the site is indexed and ranks, but I am asking if there is a particular tool out there that would provide more information if a website had been shady. Thanks so much, guys! Lily
