Why do some sites have a higher Page Authority than Domain Authority in OSE??
-
Hi,
I have noticed when using OSE and enter a domain you very often see a higher Page Authority than Domain Authority.
If someone could explain why this would happen then I would be very grateful - its my current understanding that page authority would ALWAYS be LESS THAN Domain Authority but that is not always the case (I have seen cases where PA is more than 10 higher then DA)
Here's an example where PA > DA

Thanks

No, there are too many open variables: age of pages, localization, keyword popularity, etc.
Edit: look at mozTrust of urls and domain mozTrust of various sites. This will show you that a + b is not equal to c.
hope it helps clarify.

Hi Rob & Rand,
Many thanks for helping explain the concept. What I am trying to understand is if DA is a calculation based on PA of all pages on that domain (or if it is possible to work out DA from PA of all pages on that domain) or a totally separate calculation which incorporates other metrics. EG
A domain has 2 pages A (PA 50), B (PA 40). Is it possible to work out what DA is for this domain from these 2 values alone?Many thanks

An indervidual may be rated higher then the team he plays for, a page can be rated higher then the domain it belongs to.

Well,
Sorry, your understanding is incorrect. Domain authority is just that, an overall value for the domain. So, if you go to a site where the links all come to a home page or the vast majority do, you are going to see a high PA for the home page PA. If that same site has 50 pages with few links you are going to see a lot of PA=1.
So, while the home page is important it does not outweigh the fact that overall the site is not that highly trafficked. This is a reason sites have trouble with conversions of inner pages sometimes. All the value is placed on the home page and someone then has 500 internal links from that page so it does not even help the inner pages.
Remember this in the search engine world pages are ranked and not sites. So, PA is more important from that point of view.
Hope this clarifies,
Best

Moz Domain Authority [Megathread]
Hey Moz Community, We've noticed that there are questions about Domain Authority, what it is, and how to positively impact it. We're here to answer your questions! For a full overview, please see our help hub article here: https://moz.com/learn/seo/domain-authority First, it's important to keep in mind that Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). It is not a Google ranking factor. Domain Authority scores range from one to 100, with higher scores corresponding to a greater likelihood of ranking. Since DA is based on machine learning calculations, your site's score will often fluctuate as more, fewer, or different data points become available and are incorporated into those calculations. For instance, if facebook.com were to acquire a billion new links, every other site’s DA would drop relative to Facebook’s. Because more established and authoritative domains like Facebook will have increasingly larger link profiles, they take up more of the high-DA slots, leaving less room at the higher end of the scale for other domains with less robust link profiles. Therefore, it's significantly easier to grow your score from 20 to 30 than it is to grow it from 70 to 80. For this reason, it’s important to use Domain Authority as a comparative metric rather than an absolute one. The best way to influence your DA is to improve your overall site health with a focus on the quality and quantity of external links pointing to your site. Check out this video for more details on how to impact DA Happy analyzing!

Pages with URL Too Long
Hello Mozzers! MOZ keeps kindly telling me the URLs are too long. However, this is largely due to the structure of E-commerce site, which has to include 'brand' 'range' and 'products' keyword. For example -
Moz Pro | | tigersohelll
https://www.choicefurnituresuperstore.co.uk/Devonshire-Rustic-Oak-Bedside-Cabinet-1-Drawer-p40668.html MOZ recommends no more than 75 characters. This means we have 25-30 characters for both the brand name and product name. Questions:
If it is an issue, how to fix it on my site?
If it's not an issue, how can we turn off this alert from MOZ?
Anyone know how big an issue URLs are as a ranking factor? I thought pretty low.0 -
What to do with a site of >50,000 pages vs. crawl limit?
What happens if you have a site in your Moz Pro campaign that has more than 50,000 pages? Would it be better to choose a sub-folder of the site to get a thorough look at that sub-folder? I have a few different large government websites that I'm tracking to see how they are fairing in rankings and SEO. They are not my own websites. I want to see how these agencies are doing compared to what the public searches for on technical topics and social issues that the agencies manage. I'm an academic looking at science communication. I am in the process of re-setting up my campaigns to get better data than I have been getting -- I am a newbie to SEO and the campaigns I slapped together a few months ago need to be set up better, such as all on the same day, making sure I've set it to include www or not for what ranks, refining my keywords, etc. I am stumped on what to do about the agency websites being really huge, and what all the options are to get good data in light of the 50,000 page crawl limit. Here is an example of what I mean: To see how EPA is doing in searches related to air quality, ideally I'd track all of EPA's web presence. www.epa.gov has 560,000 pages -- if I put in www.epa.gov for a campaign, what happens with the site having so many more pages than the 50,000 crawl limit? What do I miss out on? Can I "trust" what I get? www.epa.gov/air has only 1450 pages, so if I choose this for what I track in a campaign, the crawl will cover that subfolder completely, and I am getting a complete picture of this air-focused sub-folder ... but (1) I'll miss out on air-related pages in other sub-folders of www.epa.gov, and (2) it seems like I have so much of the 50,000-page crawl limit that I'm not using and could be using. (However, maybe that's not quite true - I'd also be tracking other sites as competitors - e.g. non-profits that advocate in air quality, industry air quality sites - and maybe those competitors count towards the 50,000-page crawl limit and would get me up to the limit? How do the competitors you choose figure into the crawl limit?) Any opinions on which I should do in general on this kind of situation? The small sub-folder vs. the full humongous site vs. is there some other way to go here that I'm not thinking of?

Is there a way to get the domain authority of a subdomain?
For example, www.storage-mart.com and us.storage-mart.com both show the same DA in OSE. I believe it's the DA of the root domain. How can I compare the DA of the 'www' and 'us' subdomains?

Domain / Page Authority - logarithmic
SEOmoz says their Domain / Page Authority is logarithmic, meaning that lower rankings are easier to get, higher rankings harder to get. Makes sense. But does anyone know what logarithmic equation they use? I'm using the domain and page authority as one metric in amongst other metrics in my keyword analysis. I can't have some metrics linear, others exponential and the SEOmoz one logarithmic.

Batch lookup domain authority on list of URL's?
I found this site the describes how to use excel to batch lookup url's using seomoz api. The only problem is the seomoz api times out and returns 1 if I try dragging the formula down the cells which leaves me copying, waiting 5 seconds and copying again. This is basically as slow as manually looking up each url. Does anyone know a workaround?
