    Hi there,
    I have learned that PA/DA or Domain rank etc. are more accurate indicator for domain's strength as a backlink source.
    I'm now trying to buy some aged domains and looking at these numbers but they are very different.
    This is the same for trust flow/citation flow from Majestic.

    From your experience which one is more accurate?
    One domain I was checking has the ahrefs domain rank of 37 and Moz domain authority of 16.
    Also with Majestic it got trust flow 1(one) and citation flow of 7.

    I really got confused. :confused:

    Thanks.

    I used to think so to. However I've also run across domains that had decent PA/DA with nothing but spammy social bookmarks. Which confused me to death not understanding how that was possible. I now think PA/DA is a metric to help not something to be relied upon. I find majestic trust flow to be a little better for indicating the QUALITY of the links. Though ahrefs has more results.

    Check PR, Moz PA/DA, and then check ahrefs to see what the backlink profile looks like, and finally use waybackmachine to see what type of content and website used to be hosted on the domain! :)

    Go for the domains in which DA is more than 25 and Moz Rank is more than 4 or close to 4.

    DA/PA can be easily manipulated just as PR can. A more solid indicator is Majesticseo Trust Rank or Ahrefs rank

    I have seen Moz doesn't index links built with GSA , while ahrefs manages to crawl a higher proportion of links, ahrefs seems to have a bigger database than moz . Also don't trust only 1 stat software , always use 2/3 services while gauging the authority of a domain .

    All metrics but PR are irrelevant. Search domains with PR, check if it is not fake, then look up domain backlinks in ahref, majesticseo and opensiteexplorer, look up domain history in archive.org and use your brain to judge if these backlinks are good or not. You will be fine then.
    Come on, you don't buy hundreds of domains a day, it is not that hard to look on the backlinks and domain history yourself for a couple of domains.

    No I'm not. When I see DA/PA references, especially (unlike in this thread) in link selling treads, I know this thread is borderline scam. Lots of noobs have an opinion imposed on them that DA/PA are somehow relevant to the quality of a site and to the power of backlinks from this site. They are wrong. Google does not know anything about these metrics, and moz/majestic don't know anything about google algo. It is very possible to have a completely deindexed site with high DA/PA, I had such sites myself.

    Google does know about PR for sure. So the first thing we need to look at is PR. In some cases (a site was offline too long time) it can be already n/a though. But usually PR is the thing we look for.
    When we found a domain with PR, we must ensure that the PR is not fake.
    Then we need to have look on the backlinks. Are there enough of these backlinks and do they have PR? Do the backlinking sites look like quality sites? Are there backlinks from xrumer/scrapebox comments, spinned articles, shitty article directories, obviously paid link networks? What are anchors of these backlinks, anything related to spammy niches?
    Everything looks ok with backlinks? Then the next step is to look up domain history in archive.org. How many times this domain was dropped? What kind of site was on this domain prior to the last drop? Anything like pharma/adult/article directory/so called "blog" with so called "articles" written by barely literate people for peanuts/replica/fakes/writing services/etc? No? Then let's check why the site was dropped. Was there a redirect to the new site of the same company? Maybe they moved the site without redirect, and the content of this site can be found on that new site? Maybe there are signs it could be deindexed for something? Everything looks ok? Then the domain might worth something.
    I honestly don't see how metrics such as DA/PA can help with this process of domain evaluation, and what exactly they show. All I can see they are kind of snake oil in SEO.

    I'm surprised people don't use Majestic Trust Flow (and Citation Flow also even it's more easy to manipulate) more. It's most reliable metric nowadays when PR isn't that much of factor anymore.

    Not a scientist in this matter but from my experience use all to get a general idea of what the domain is all about and drilldown for more info by hand as necessary, I wouldn't just trust the numbers (maj/moz/pr) without looking into ahrefs (seems to have the most data on backlinks) to see what's there and get an idea of whether the domain has been abused or not. I think PR is very important but as a metric not so much since it is updated so rarely you have to use other metrics to get an idea of current status of a domain. PR0 sites can be worthwhile for this reason just like a PR4 domain might be worthless. If you're working with volume you have to make guesstimations based on these metrics (low pr, high da, high maj trust, probably good). Really manual checking is always the most accurate way to understand what you're dealing with.

    PR is still my preferred metric over anything else, because as long as it's not fake, google actually approved and scored that domain at one point. The other metrics like PA/DA may be more up to date, but they are ultimately a best guess at what google is looking for, and can be manipulated. Also Moz never seem to show anywhere near my actual number of backlinks, where Majestic and Ahrefs are usually pretty good. In that sense, I would say trust the metrics of them over Moz.

    Ofcourse you can look at the metrics all you want, but nothing really beats manually checking the domain from human perspective. Check wayback - Does it look like it was and always has been a legitimate site? Check the backlinks - Do they look like they are from legitimate sites? If it was a legitimate site, that has been around for a long time, it's going to have good links. Look for spam pointing at your domain, if you find any, move on. If all this checks out, and you seem some good metrics, you're good!

    People are pretty stupid when it comes to logic.

    PR; a metric that was once so crucial, a year later is now on the complete opposite end of the spectrum. Going from one extreme to the other (DA) in the course of a year is hardly logical at all.

    The correct answer to take a more broad approach and look at the whole rather than a single metric; though collective PR still holds the most weight for me

    Seems to me that guys like Hayden and other Domain Brokers set the standard for DA being superior to push their shitty domains at you for 150$ a piece

    As someone who has investigated hundreds of domains, I can tell you for sure that DA/PA is easily attained through spammy links. I've seen huge numbers on domains that even have hidden injection links - super spammy stuff.

    It's really something you need to take a 360 view on - look at all the metrics in combination. Check for spammy backlinks looking at anchor texts, and don't forget WOT. WOT's not perfect but when examining a site I do take a look at it.

    Also check the history on domain tools if you have an account, and don't forget checking Archive.org.
