Check spam score and Domain Authority of a site.

Fist of all check the DA of that website and its spam score by using mozbar extension and then check whether that site is relevant to my site, because site relevancy matters a lot in off-page of SEO

@Valuehits123 Check what @lonelysoul wrote. He said it correctly depending on DA for checking a single link is never a wise decision.

Monitor Backlinks also makes it significantly easier to identify and handle bad backlinks. After you add your domain, you can head straight to the “Your Links” tab to see all of your backlinks in one place. In Monitor Backlinks, problematic links are flagged with a “warning” icon on the farthest-left column

There are some metrics on which behalf we differentiate good and bad links such as;
Is the link on a page of a weak domain?
Is the link on a page that is blacklisted or banned?

Is the link on a spammy directory?

If your links are coming from unrelated sites or pages, they'll be regarded as bad links. If you are an internet marketing expert, don't try to get links from fitness blogs, because they are not related.
