      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.

                        Is link equity passed through redirect chains?

                        Hi there, When redirects are passed through multiple stages e.g. https://www.google.com 301 to http://www.bing.com 301 to http://www.yahoo.com Does http://www.yahoo.com still retain all link equity from the original referring domain, and is there a limit to the redirect chain before Google starts to not pass through link equity? Cheers

                        Do Canonical Tags Pass Link Juice?

                        I have an ecommerce website where some pages link to a product page with a different URL. EXAMPLE: 1: /category/product1.html (not indexed by Google) with canonical pointing to product1.html Other page link to the product like below. 2: product1.html (indexed by Google) Now the question is, does 1: pass any link juice to product1.html or not? Is it worth to change everything and link only to one URL? My site is running on Magento!

                        How do I redirect the Author archive page in Wordpress?

                        If you do a search for my name on Google, the first result is the author archive page of my Wordpress blog. I would like to redirect the author page to my  "about me" page but cannot add a 301 as the author page is created dynamically in Wordpress. Anyone know how I can do this?

                        Remove page with PA of 69 and 300 root domain links?

                        Hi We have a few pages within our website which were at one time a focus for us, but due to developing the other areas of the website, they are now defunct (better content elsewhere) and in some ways slightly duplicate so we're merging two areas into one. We have removed the links to the main hub page from our navigation, and were going to 301 this main page to the main hub page of the section which replaces it. However I've just noticed the page due to be removed has a PA of 69 and 15,000 incoming links from 300 root domains. So not bad! It's actually stronger than the page we are 301'ing it to (but not really an option to swap as the URL structure will look messy) With this in mind, is the strategy to redirect still the best or should we keep the page and turn it into a landing page, with links off to the other section? It just feels as though we would be doing this just for the sake of google, im not sure how much decent content we could put on it as we've already done that on the destination page. The incoming links to that page will still be relevant to the new section (they are both v similar hence the merging) Any suggestions welcome, thanks

                        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?

                        Do I need to add canonical link tags to pages that I promote & track w/ UTM tags?

                        New to SEOmoz, loving it so far. I promote content on my site a lot and am diligent about using UTM tags to track conversions & attribute data properly. I was reading earlier about the use of link rel=canonical in the case of duplicate page content and can't find a conclusive answer whether or not I need to add the canonical tag to these pages. Do I need the canonical tag in this case? If so, can the canonical tag live in the HEAD section of the original / base page itself as well as any other URLs that call that content (that have UTM tags, etc)? Thank you.

                        Do Backlinks to a PDF help with overall authority/link juice for the rest of the domain?

                        We are working on a website that has some high-quality industry articles available on their website. For each article, there is an abstract with a link to the PDF which is hosted on the domain. We have found in Analytics that a lot of sites link directly to the PDF and not the webpage that has the abstract of the article. Can we get any benefit from a direct PDF link? Or do we need to modify our strategy?

                        Deep Page Link - url no longer exists

                        I used Open Site Explorer and found a link to our site on http://www.business.com/guides/bedding-supplies-3639/  The link was setup to go to an important, deep page on my website, but the structure of our urls changed and the url no longer exists. The link (anchor text 'National Hospitality Supply') does direct to our homepage, www.nathosp.com. My question is, am I receiving full link juice? Or would I be better served to create a 301 redirect to the revised / new page url? In case it matters, if I had my choice I'd prefer the link to go to the intended deep page. Thanks in advance for your insight. -Josh Fulfer
