      Hello,

      Let's say that there is a link to site A from site B. The domain authority of site B is 85, but the link is on a page that has a page authority of only 1. Does much authority get passed along from site B to site A? (Let's assume site A has a domain authority of 35, if that's relevant.)

      Thank you!

              Unfortunately, Dr. Matt's out of town, so this answer won't be as thorough as I'd like, but the gist of it is that we factor in both DA and PA to some degree. If a site has very high DA but a very low PA (as in your example), we're going to bias somewhat toward the DA, as we believe Google sometimes does (a virtually unknown page on Wikipedia can rank very well, for example). Likewise, a high-PA page on a site with low DA may pass more through the PA, because (hopefully) that page has some legitimate authority.

              It's a bit more complex, because DA and PA are related as well, so they do influence each other to some degree. On larger sites, the influence of any single page's PA is small, but the influence can be more obvious on smaller sites.

              Putting aside our math, I think a link from a low-authority page on a high-authority site can be worthwhile. Look at directories, like DMOZ. I think it's important to make sure the low-PA page is indexed (some DMOZ pages aren't, because they're buried so deeply in the link structure), and I wouldn't get hung up on a link from a high-DA site. It's ultimately just one link. I wouldn't dismiss it as useless either, though. There's some amount of site/page balance in the mix and Google doesn't rely on only one type of authority.

                I'm checking with Dr. Matt Peters, head of our Data Science team. It's less about secrecy and more that DA/PA are based on machine learning and have gotten a bit complex. Still, I suspect we can give you a general sense of how DA/PA pass through links. Posting this because I suspect an answer may take a day or two.

                  Well, it is a bit late for regular office hours for most Moz staff, so you may not hear an answer until tomorrow. The answer may also include "remember, what the search engines think is what matters", but you should get an answer with at least some information in the next couple of days.

                    and I am sure Moz will not answer this at all! 🙂

                      It is, but no one outside Moz can answer that, there are several metrics that affect authority passing, and I guess that most of those metrics and algos are property of Moz and most likely secret to prevent abuse.

                        domain authority optimization

                        In my latest site crawl, the domain authority dropped 10 points for no apparent reason. There have been no changes to the site. The only change I have made this month is to block referral spam to the site. My competitors' DAs have stayed the same too. website name: https://knowledgefront.co.uk/ Any ideas?

                        How effective are 301 redirects in passing page rank?

                        301 redirect page rank

                        I have a blog which is ranking well for certain terms, and would like to repurpose it to better explain these terms it is ranking for, including updating the url to the new term the blog will be about. The plan being to 301 redirect the old url to new. In the past, I've done this with other pages, and have actually lost much of the rankings that I had earned on the original URL. What is your take on this? Maybe repurpose blog, but maintain original URL just to be on the safe side? Thanks

                        Can I use a 301 redirect to pass 'back link' juice to a different domain?

                        Hi, I have a backlink from a high DA/PA Government Website pointing to www.domainA.com which I own and can setup 301 redirects on if necessary. However my www.domainA.com is not used and has no active website (but has hosting available which can 301 redirect). www.domainA.com is also contextually irrelevant to the backlink. I want the Government Website link to go to www.domainB.com - which is both the relevant site and which also should be benefiting from from the seo juice from the backlink. So far I have had no luck to get the Government Website's administrators to change the URL on the link to point to www.domainB.com. Q1: If i use a 301 redirect on www.domainA.com to redirect to www.domainB.com will most of the backlink's SEO juice still be passed on to www.domainB.com? Q2: If the answer to the above is yes -  would there be benefit to taking this a step further and redirect www.domainA.com to a deeper directory on www.domianB.com which is even more relevant?
                        ie. redirect www.domainA.com to www.domainB.com/categoryB - passing the link juice deeper.

                        When you change your domain, How much time do I have to wait for google to return the traffic used to have?

                        Hello. 20 days ago, I changed my domain from uclasificados.net to uclasificados.com doing redirect 301 to all urls, and I started to loose rankings since that moment. I was wondering if changing it back could be the solutions, but some experts recommend me not to do that, because it could be worse. Right now I receave almost 50% of traffic I used to receave before, and I have done a lot of linkbuilding strategies to recover but nothing have worked until now. Even though I notified google of this change and I send again my new sitemap, I don't see that have improve my situation in any aspects, and I still see in webmastertools search stats from my last website (the website who used to be uclasificados.com before the change). What should I do to recover faster?

                        Redirecting root domain to a page based on user login

                        We have our main URL redirecting non-logged in users to a specific page and logged in users are directed to their dashboard when going to the main URL. We find this to be the most user-friendly, however, this is all being picked up as a 302 redirect. I am trying to advise on the ideal way to accomplish this, but I am not having much luck in my search for information. I believe we are going to put a true homepage at the root domain and simply redirect logged in users as usual when they hit the URL, but I'm still concerned this will cause issues with Google and other search engines. Anyone have experience with domains that need to work in this manner? Thank you! Anna

                        Too Many On-Page Links - caused by a drop down menu

                        Many of our e-com sites we build for customers have drop down menus to help the user easily find products without having to click - Example: http://www.customandcommercial.com/ But this then causes the report to trigger too many on page links We do have a site map and a google site map So should I put code in place not to follow the drop down menu link items or leave in place?

                        Domain authority and keyword difficulty

                        I know there are too many variables for a certain answer, however do people take their domain authority into account when using keyword difficulty tool? I have a new domain which only has a score of seven at the moment.  When using the keyword searching tool what is the maximum difficulty level keywords people would target initially? Obviously I would seek to increase the difficulty of the words over time but to start off its a hard choice between keywords which can be ranked for in a reasonable period of time and the keywords which are getting enough traffic to make the effort worthwhile.

                        .com or .co.uk in UK index? but the .com has higher domain authority...

                        Hi there i have a .com and a .co.uk for a site that has been around a while. However not much seo has been done on it, i was wonderign do i continue to optimise for the .com or switch to the .co.uk to rank in Google UK index for various search terms. .COM = 40 domain authority .CO.UK - 10 domain authority. Let the debate start 🙂
