Why MoZ Bar gives different PA and DA to my homepage? Surly they should have the same metrics?
-
Hi guys, is it normal that when looking at my homepage with the mozbar i get the same DA and PA? It seems that it should provide the same results.
Thankss
-
Yes, that is exactly it. And yes, your curiosity should never be completely satisfied...
-
Hi Linda,
Now this starts to make sense. Based on your assumption that the DA is calculated based on the entire site (i.e. all pages) and the PA is based on a single page it will make sense. i guess it is the difference of evaluating your "House" as a whole or just the "Front Door" when you stand in-front of it.
I think that has satisfy (for now...) my curiosity.

The root domain does not have the same data as the homepage.
The domain authority takes the entire website into account and the homepage page authority takes only one single page, the homepage, into account.
Look at Moz again as an example. The homepage has 342,922 links from 11,650 root domains. The root domain has 15,899,372 links from 46,201 root domains. So they are not the same.
I do not know the mysterious details of how the authorities are calculated, but they are taking different data into account and one is looking at a single page while the other an entire site so it is not at all surprising that they can be different.

Hi Linda,
Thanks for the reply. What you are mentioning above is correct. i mean, this is what we are experiencing but feel it is not right, therefore wanted to understand why is that happening? and why the two metrics do not match? How can it be that the same page (i.e. homepage and root domain) give different metrics they have the exact same data.
and assuming there will be an argument that explain that strange behaviour, which of the two metrics should we take in consideration?

All pages on your domain have the same domain authority. Each page has its own page authority.
The page authority of the home page can be the same as the domain authority, but it does not have to be.
For example, the page authority of moz.com (homepage) is 92 (looking at the moz bar) and the domain authority is 93. For www.macys.com (homepage) the page authority is 90 and the domain authority is 87.

i will be waiting in anticipation for one of the MoZ's to share some light on this.

You got me I have no idea why you would be getting different metric's I agree they should pull from the same scrape ? Although now you have me on a mission to find out why

Hi Ryan,
Yes, im talking about the MoZ Pro bar (PA, mR, DA). "Page authority" and "Domain Authority" are both MoZ metrics, and whilst on the root of my site (i.e. my homepage) they should both provide the same metric.
Thanks,

You may have already read this but this is a great article about the DA and PA may throw some light for you Sir. http://moz.com/blog/whiteboard-friday-domain-authority-page-authority-metrics
All the best

So I think I get it now your saying that the Moz Bar is giving different data from Moz pro? I think I am getting what your saying, (just as note I have also noticed that there are times with SEM Rush for example that the data is "screwy" to say the least. ) I remember just before the christmas break SEM was reporting every keyword we track as down -99 positions, HEART ATTACK time !! So has this been going on for a while or just an isolated thing? I have always followed the approach that a single source of data or information is just that a single source, I would try cross referencing the metric with other tools and compare.
"One thing is for sure as SEO's we need many baskets and many eggs, to have one of each would be foolish." I wait to hear from you.

Hi Ryan,
Thanks for the reply. Let me try and be more specific. When i visit my homepage (root domain) the PA and DA are exactly the same. So my www.rootdomain.com (which is also the homepage) should give the exactly same Page authority and Domain authority metrics.
am i missing something?
-
Hi there so are you saying that you Domain Auth and Page Authority are the same throughout your site or just on one page, can you supply the URL please. It's possible that the 2 metrics are the same currently. have you been tracking the over time so you can do a comparison?? Please post back.

DA hasn't Moved over
We moved our site over a couple of weeks ago from bi-mi.com to bimi.co - its a magento site. We followed instructions to wait 2 weeks and upload a coming soon page etc to help google realise it was not just a parked domain. We moved everything over and then set a hta record up to redirect the "bi-mi" base domain to "bimi" , we then logged teh site move within web master tools also and I set the bimi.co preferred url etc. However its been about a week and half now and the DA is still showing as 1 and bi-mi (the old site that is redirecting) is showing as 18 Is it just patience needed here or have any of you also come across this issue?

Does using Sucuri block Moz?
I am using Opensite explorer on my site which uses Sucuri and it shows 0 for everything. Does Sucuri stop MOZ from reading the link? I also suspect that using Sucuri has made my SEO suffer because the first page is always saying "redirecting" . Anyone with experience to this? Thanks

Why Moz Doesn't See or Count Our Backlinks?
Hi Moz Community! We have been working hard to improve our Moz metrics, measuring against a high ranking competitor to help us set our goals. Our Majestic and Webmaster Tools find tens of thousands of external backlinks pointing to our domain. That's all well and good. Moz's Open Site Explorer, however, only finds 900 total links - including internal links! This being the case, we have worked diligently to build a variety of great external backlinks, creating Bitly links and encouraging clicks on those through social promotion. Yet, our competitor has over 7,000 external backlinks in Moz's index, while ours is not growing relative to their number of backlinks. Can anyone share with us what they do to tell Moz about their backlinks? We already know we have many more backlinks than our competitor, from trusted domains with good authority, yet it seems Moz is not discovering them. We just want to understand how to use these Moz metrics to create meaningful calls-to-action. Otherwise, it seems like a gargantuan waste of time, and our team has difficulty getting buy-in from our company to put time and assets toward tasks based on our Moz numbers!

How long does it take for moz to index new domain?
Hi, Two months ago we changed our site www.jicht.nl to jicht.nl. Everthing is redirected properly but the page authority remains 1. How long does is take rogerbot to index the site without www? Google rankings are also dropping so there might be a bigger issue. Thanx
