Non spammed .edu linked expired domains - any good?

hi guys, ive found a number of expired domains that have genuine .edu links rather than ones from edu spam blogs, they might only have 10-30 links with maybe 3-5 on .edu sites
opensiteexplorer gives them on average 15-20 domain authority and 20-30 page authority - will these be ok for my PBN or are they still pretty weak?
Thanks

These Moz metrics are easily manipulated, and they are only based on the backlinks that Moz has crawled.

Use DA/PA as a filter to help you find a point of reference where to look. Buy the domains based on the backlink profile, not any metric.

If I found a web site with DA 0 and PA 0 and it had 5 .EDU backlinks with PR I'd buy the crap out of that domain. I don't care what moz, majestic, ahrefs, any of them have to say about it. What matters more than anything is the backlinks, and the archive.org history.

Would you like those 5 .EDU links pointing at your site? If so would you pay 9 dollars for them? That's what it's going to cost you if you buy this domain.

If the .edu links are do-follow and contextual then they are valuable. Don't go for PA/DA, it's the link profile that matters.

Also have a look at the trust flow and the anchors to the site and make sure no jp or cn sites link to the domain because if thats done then its probably a spammed domain 90% of time

I'd echo the other replies and say that while metrics can give you a sense of worth, they are no substitute for a bit of common sense. You have to ask yourself: will Google, or any other search engine for that matter, look favourably on these genuine, trustworthy links?

Saying that, the metric I tend to favour over any other is the MozTrust of the root domain.

You can find this by going to http://www.opensiteexplorer.org/comparisons?site=http://www.yourdomain.com and entering this domain instead and then scrolling to the bottom where the root domain metrics are. I like to see a score above 4 but it is by no means a deal-breaker if it's lower.

Like most things with SEO, it all boils down to testing to see if something is beneficial or harmful. Our speculations and rules-of-thumb are good for guidance, but the tests are the real answers.

If they're expired, then you're just paying the registration fee. Use the Honey plug-in on Chrome to apply a coupon code and get it for $2. Set it up and point it to a test site ranking for something ridiculous like "star wars dolphins". See if it causes a positive movement on the SERPs.

If so, you just got yourself a $2 PBN. If not, use it as a Tier 2.
