Getting Different PA/DA for 'www' and 'non-www'?
-
Can anyone explain why we're seeing different DA/PA for our website when viewing in OSE for 'www' and 'non-www'? This is for our site whiteboardcreations.com
Our 'www' is resolving at DA 37 | PA 47
Our 'non-www' is resolving at DA 37 | PA 44Thanks! - Patrick

Thank you for the explanation, Prestashop. I'll have to look into this ASAP. We thought we had set all of that up, but now seeing something went awry.

Thanks, Keri. I suspected that.

From what I have personally seen with Moz is that it calculates DA based on the whole domain and passes the same DA to all of the sub domains of the site. So that would explain why the DA is the same for both urls, since www is considered a sub domain.
For the PA what it means is that more than likely your site is accessible from both the www and non www urls. This creates duplicate content, but at the same time it splits the page's authority as well. The reason being is that Google will see them as two different pages, but they have the same content. Then also some users might enter with the www and some without. Then those people might want to link to your site, some will use the www and others will not use the www. So you are basically creating two different link profiles for the site.
I would add a canonical tag to the site if you are going to keep it this way, then it will be known to search engines which site is the preferred one. Ideally, you should put a redirect and choose to go with using the www. or not using a prefix at all, but not both at the same time, then add a canonical tag too for good measure.

Hi! The page authority is different because those are actually two different URLs. You probably have more backlinks going to one URL than to the other. If it's not already set to redirect from one version to the other site-wide, I'd set that up (tethering right now and don't have much bandwidth to check).

Our Domains DA has dropped from 52 to 17
Hi,
Link Explorer | | JudyLam
Our domain's DA (www.tricorglobal.com) has dropped drastically from 52 to 17 on Mar 2019. And has only gone up to 21 now. Is there a reason why this happened. On the other hand, our competitor's score has increased. Is there a valid reason for this? How can I find out what is hurting our DA and how can I fix this?1 -

(301 Redirect) Link Spam Score: 10/17
Hi everyone, I'm looking for a specific answer, so I'll give some specifics to help get some information. https://moz.com/researchtools/ose/links?site=http%3A%2F%2Fgpstrackit.com%2F&filter=&source=external&target=page&group=0&page=1&sort=page_authority&anchor_id=&anchor_type=&anchor_text=&from_site= After looking through Open Site Explorer we've noticed one of the links from login.gpstrackit.net has a 10/17 spam score. https://moz.com/researchtools/ose/spam-analysis/flags?subdomain=login.gpstrackit.net This link is a 301 redirect from a previous login URL, so users can be redirected to our current site and login from there. I don't know how to approach this situation or what the correct fix is. Any advice would be much appreciated!

Why aren't my "page social metrics" increasing?
I post a lot to Facebook & twitter, & my "page social metrics" haven't budged in 4 weeks. I even stopped using bit.ly & stated the full URL as a test. Still no change. The fb account is /getgoodgifts & twitter is /giftsing. Thoughts on why social metrics aren't increasing?

DA/PA Fluctuations: How to Interpret, Apply, & Understand These ML-Based Scores
Howdy folks, Every time we do an index update here at Moz, we get a tremendous number of questions about Domain Authority (DA) and Page Authority (PA) scores fluctuating. Typically, each index (which release approximately monthly), many billions of sites will see their scores go up, while others will go down. If your score has gone up or down, there are many potential influencing factors: You've earned relatively more or less links over the course of the last 30-90 days.
Link Explorer | | randfish
Remember that, because Mozscape indices take 3-4 weeks to process, the data collected in an index is between ~21-90 days old. Even on the day of release, the newest link data you'll see was crawled ~21 days ago, and can go as far back as 90 days (the oldest crawlsets we include in processing). If you've done very recent link growth (or shrinkage) that won't be seen by our index until we've crawled and processed the next index. You've earned more links, but the highest authority sites have grown their link profile even more
Since Domain and Page Authority are on a 100-page scale, the very top of that represents the most link-rich sites and pages, and nearly every index, it's harder and harder to get these high scores and sites, on average, that aren't growing their link profiles substantively will see PA/DA drops. This is because of the scaling process - if Facebook.com (currently with a DA of 100) grows its link profile massively, that becomes the new DA 100, and it will be harder for other sites that aren't growing quality links as fast to get from 99 to 100 or even from 89 to 90. This is true across the scale of DA/PA, and makes it critical to measure a site's DA and a page's PA against the competition, not just trended against itself. You could earn loads of great links, and still see a DA drop due to these scaling types of features. Always compare against similar sites and pages to get the best sense of relative performance, since DA/PA are relative, not absolute scores. The links you've earned are from places that we haven't seen correlate well with higher Google rankings
PA/DA are created using a machine-learning algorithm whose training set is search results in Google. Over time, as Google gets pickier about which types of links it counts, and as Mozscape picks up on those changes, PA/DA scores will change to reflect it. Thus, lots of low quality links or links from domains that don't seem to influence Google's rankings are likely to not have a positive effect on PA/DA. On the flip side, you could do no link growth whatsoever and see rising PA/DA scores if the links from the sites/pages you already have appear to be growing in importance in influencing Google's rankings. We've done a better or worse job crawling sites/pages that have links to you (or don't)
Moz is constantly working to improve the shape of our index - choosing which pages to crawl and which to ignore. Our goal is to build the most "Google-shaped" index we can, representative of what Google keeps in their main index and counts as valuable/important links that influence rankings. We make tweaks aimed at this goal each index cycle, but not always perfectly (you can see that in 2015, we crawled a ton more domains, but found that many of those were, in fact, low quality and not valuable, thus we stopped). Moz's crawlers can crawl the web extremely fast and efficiently, but our processing time prevents us from building as large an index as we'd like and as large as our competitors (you will see more links represented in both Ahrefs and Majestic, two competitors to Mozscape that I recommend). Moz calculates valuable metrics that these others do not (like PA/DA, MozRank, MozTrust, Spam Score, etc), but these metrics require hundreds of hours of processing and that time scales linearly with the size of the index, which means we have to stay smaller in order to calculate them. Long term, we are building a new indexing system that can process in real time and scale much larger, but this is a massive undertaking and is still a long time away. In the meantime, as our crawl shape changes to imitate Google, we may miss links that point to a site or page, and/or overindex a section of the web that points to sites/pages, causing fluctuations in link metrics. If you'd like to insure that a URL will be crawled, you can visit that page with the Mozbar or search for it in OSE, and during the next index cycle (or, possibly 2 index cycles depending on where we are in the process), we'll crawl that page and include it. We've found this does not bias our index since these requests represent tiny fractions of a percent of the overall index (<0.1% in total). My strongest suggestion if you ever have the concern/question "Why did my PA/DA drop?!" is to always compare against a set of competing sites/pages. If most of your competitors fell as well, it's more likely related to relative scaling or crawl biasing issues, not to anything you've done. Remember that DA/PA are relative metrics, not absolute! That means you can be improving links and rankings and STILL see a falling DA score, but, due to how DA is scaled, the score in aggregate may be better predictive of Google's rankings. You can also pay attention to our coverage of Google metrics, which we report with each index, and to our correlations with rankings metrics. If these fall, it means Mozscape has gotten less Google-shaped and less representative of what influences rankings. If they rise, it means Mozscape has gotten better. Obviously, our goal is to consistently improve, but we can't be sure that every variation we attempt will have universally positive impacts until we measure them. Thanks for reading through, and if you have any questions, please leave them for us below. I'll do my best to follow up quickly.13 -

OSE Getting Less Accurate
It seems that the more links I get the lower my DA is. My DA has been dropping for some time now as I gain more backlinks. It also does not seem to pick up anywhere close to the number of domains that is linking to my site. My url is hiddentriforce.com GWT says I have over 600 domains linking in. The majority of the links are from news or articles that we cover which other sites pick up and link to us as the source. We also have a ton of scholarship links from .edu and education sites from a giveaway that we do every year for students. Why does OSE seem to lower my DA the more I get off-page factors to the site?
