I'm trying to improve my website's SEO and focusing on earning more natural links . But with so many different link-building strategies out there, it's hard to know if my efforts are paying off.

I recently found a couple of online calculators that claim to assess the quality of backlinks based on certain metrics (domain authority, relevance, etc.). Do you think these tools are effective at identifying natural links, or are they more geared toward analyzing paid or spammy ones?

Would love to hear your experiences with these calculators and how you track your link-building progress.
