Doubt - this domain is bad?

I have bought recently an expired domain that have like 37k backlinks but I checked and those are real non spammy backlinks, even have some real wikipedia and government sites.

The stats are these: DA 21 PA 34, TF 15 CF 26. I also have checked on webarchive and domain have not been never 301 redirected to another domain. What concerns me is about the high number of backlinks, is this bad on eyes of google? Even if the backlinks are non spammy generated by software?

If they area real non spammy and have wikipedia and government links andhas such good DA, PA, TF CF then absolutely it'll be a good domain to catch, there are good websites with high number of backlinks on the new such as Google it self so it's not bad.

Did you check the anchor text cloud?

I would be concerned about the ratio of CF/TF. The CF is almost double the TF. Domains with natural back links tend to have the ratio closer to 1. I suspect there will be a few links from sites that are spammy. A quick check of the back links should help you figure this out.

37K back links by itself need not be a bad thing. You could have a site wide footer/sidebar link from a website with 37K pages indexed. Google will treat this as one link.

I would also check the total number of unique ip/subnets that the links are coming from as well. When buying an expired domains for its back links you want to buy a domain that will retain the back links. If all the "good" backlinks are from a single domain, there is too much risk that the domain webmaster removes the site-wide link and renders the domain worthless.

To have 37k of natural links it should be very popular domain, which i doubt it was as it was let to expire. So likely there are all kind of backlinks beside the good ones. Also anchor distribution and other aspects would be relevant. Try to see if site was penalized or not and check past ranking.

nobody can tell you if this domain is good or bad before he checked the backlink profile. It is not possible to give you an assessment based on the few metrics you mentioned.

How many root domains are we talking about here? Surely it's just a case of putting the domain into ahrefs or majestic, looking at the referring domains and then checking those that seem to be providing the bulk of the backlinks. Chances are it's some sort of thing with dynamic pages being counted multiple times by the backlink checkers due to slight variations of the URL - it happens all the time. Or you have a sitewide link - that's no problem in itself.

You can hire a due dilligence professional from this forum...they'll let you know if the domain is good/bad professionally.
