DA/PA Question
-
Hello Mozzers,
May be a noobish question but I've learned to ask when I stuck.
Can we calculate how many links we need to get for example a domain authority of 40. Like can we say, if we get 8 more 80+ DA links, our own DA rises to 40. I know DA/PA are just moz numbers and it takes a lot more to succeed, but I thought about it and now I want to know it;)
Help is highly appreciated!

Thank you for the help, thats exactly what I was looking for!

Ah, this is definitely a more nuanced answer than just X links = Y DA/PA... The TL;DR is take a look at sites similar to yours in the Comparison Tool to get an idea around goal numbers. https://moz.com/researchtools/ose/comparisons
Rand has presented on this in the past, and here's one of his answers from the blog that should give you a good idea of what's taken into account...
Q: Can you speak in more detail about the specific metrics that are being used to calculate the domain/page authority?
You talked briefly about this in video 2, and it makes sense that you're using already existing metrics like mozRank, mozTrust, number of links and number of linking domains. But what are the other metrics you use (those "dozens or hundreds" of link metrics)?
Rand: Just a start, but things like:
- mozRank
- mozTrust
- Domain mozRank
- Domain mozTrust
- # of links
- # of linking root domains
- % of followed links
- % of image links
- % of links from same IP c-block
- % oflinks from noscript links
- distribution of % of links from pages with certain # of links on the page
- distribution of TLDs in links
- distribution of TLDs in linking root domains
- mozRank passed through links from certain TLDs
- distribution of mozRank passed through links with certain mozTrust metrics
- mozRank passed by sites with certain DmR/DmT scores
- mozRank passed through image links
- mozTrust passed (on all of the above sets)
- relationship between each metric with each other metric
- derivatives calculated between multiple metrics (3-way, 4-way, 5-way, etc. comparisons)
I suspect there's a lot more in our formulas at this point, but you can basically think of it as us using every metric we can calculate and every metric that can be calculated off the relationship between 2, 3, 4+ metrics.As we noted in the video, the algorithms themselves are pretty hard to look at and find value from, but the concept behind it - that by mashing up metrics in ways that correlate with search rankings using machine learning you can get high value data - is what's important. Hope that helps!

Question about link report
Hey all, SEO noob here, back with another question. I downloaded a link report, and I don't understand the columns Links to Page, Outbound Domains from Page, and Outbound Links from Page. Is Links to Page the number of links from the source page to the target page? Is Outbound Domains from Page the number of domains linked to by the source page? Is Outbound Links from Page the number of outbound links to any domain or page from the source page? Thanks in advance! AK

Moz's new Link Explorer, including our revamped index and DA/PA scores is now open to everyone!
Hey Moz Community, Link Explorer is now open to the public! Everyone can access it via a subscription or a free Moz ‘Community’ account. As you may know by now, the brand-new Link Explorer tool is primed to replace Open Site Explorer as Moz’s link building and analysis tool. The Link Explorer project is the result of an incredible amount of perseverance and hard work by the team, and we’re proud to be able to finally share it with you — we know it’s going to revolutionize how you approach link building and make your job easier. You can read more about the tool here in Sarah Bird’s announcement post. Because Link Explorer improves on almost every aspect of Open Site Explorer, the metrics have improved, too. That means you’re likely going to see some Domain Authority and Page Authority discrepancies between OSE’s index and Link Explorer’s index. We definitely suggest you use the new DA/PA from Link Explorer, as they’re more accurate and refresh daily rather than monthly, as was the case with OSE’s index. However, we also realize that many of you use these metrics to report to your clients and colleagues, and a sudden change or fluctuation could potentially make your job harder. Which DA is the real DA? The new DA is based on a much larger index that has many improvements, several of which are designed to make the index more like Google’s than ever before. You should consider moving towards the new DA (and the old DA won’t be updated after April 26th 2018, so the sooner the better). While there will be fluctuations as we improve the model and add features to the index, we expect it to remain largely stable and to be a far more accurate picture of a site’s authority according to how it’s seen by Google. Why is Link Explorer’s DA/PA considered better than OSE’s, and which should I trust? The larger link index with improved crawl selection allows us to produce a stronger model that includes a much larger proportion of the web. That being said, DA and PA should always be considered in the context of your competitors. A drop in PA or DA relative to the old OSE is of little concern if your competitors saw similar movement. Is Domain Authority/Page Authority an absolute score or a relative one? Both DA and PA are relative to the Internet as a whole. If Facebook acquired a billion new links, everyone’s PA and DA would drop relative to Facebook. Because of this, it’s always best to look at PA and DA in comparison to your competitors. What does a drop/raise in DA mean in Link Explorer vs OSE? How can I explain this to my clients when I’m reporting it? DA and PA should always be considered in the context of your competitors. A drop or raise in PA or DA relative to the old OSE is of little concern if your competitors saw similar movement. Reporting that your site has moved from a DA of 45 to a DA of 42 doesn’t tell the whole story, but reporting that your site has a DA of 42 while your main competitor moved from a 43 to a 37 shows that, relative to the sites you’re competing against in the SERPs, your site has significantly more authority and ranking power. What’s happening to MozTrust and MozRank and why, and what should I replace those with? The improvements to our DA/PA and Spam Score metrics now now account for more important nuances in helping you determine one site’s ability to rank higher than another. Because they no longer correlate with Google’s ranking model as well as they used to, MozRank and MozTrust are being deprecated for better metrics. Users should rely on Page Authority, Domain Authority, and Spam Score to determine the importance and quality of pages, domains, and links. I have historical data I use to help my clients benchmark their progress. What do I do now that DA is calculated differently? You should annotate any KPI changes referencing the change in DA and PA. However, most importantly, you should compare those changes to your competitors, as this will best show how strong your site’s authority is relative to the sites you’re competing against in the SERPs. We take updating our metrics very seriously, and our last major update to the model was 7 years ago. Users of Domain Authority and Page Authority can expect us to continue to produce steady, reliable metrics for the long haul, and only make changes to these metrics when we believe the benefits dramatically outweigh the stability of the metric. Do you have any questions about the new metrics? Anticipating a tough time reporting changes to clients or bosses? Metrics, features or functionality missing that you would want to see? Let us know in the thread, and we’ll work to find a good answer for you. Hope you enjoy the new Link Explorer product and the amazing new link index powering it. We are very excited to provide this valuable data to our community and customers.

How long does it take to turn around a 10/17 SPAM score domain?
Hi - Looking at acquiring a domain name that has a great product fit. The problem is it is currently getting a 10/17 Open Site Explorer SPAM score. The existing site for the domain is running Google sponsored link ads and is full of internal pages that link off to these ads. That explains the existing SPAM score. If I acquire the domain I'll throw out the Google ad pages and build instead a site with real valuable content that behaves like a normal site and look at building backlinks etc. My question is, following this approach, how long is it likely to take Google to not see the domain as some Spam factory so it starts getting well positioned SERPs?

Flauctuating number of Internal Equity-Passing Links affecting DA
My site has a high number of fluctuating internal equity passing links in open site explorer from month to month, theses range from 30 000 and sometimes as high as 1,million. The fluctuations occur even when I have made no changes onsite. I have noticed that when the internal equity passing links are very high the DA drops and when they are low the DA is high, has anyone ever experienced this with open site explorer ?
