What Makes a Good Backlink? DA, DR, Traffic & Spam Score Explained

Key Takeaways

  • DA (Moz) and DR (Ahrefs) estimate a site's strength — use both as a guide, not gospel.
  • Real organic traffic may be the single most important signal of a healthy site.
  • A low spam score is essential; a high spam score is a reason to skip the link entirely.
  • Niche relevance on top of good metrics is the ideal combination.
  • High DA/DR with near-zero traffic can be inflated — stay cautious.
  • Always read all four metrics together, never one in isolation.

Not all backlinks are created equal. Before you pay for a link, you should be able to read a publisher's metrics and judge whether it's worth it. Here are the four numbers that matter — and how to read them.

Domain Authority (DA)

Domain Authority is a Moz score from 1–100 that predicts how well a site might rank. Higher is generally better, but DA is a third-party estimate, not a Google metric — use it as a rough guide, not gospel.

Domain Rating (DR)

Domain Rating is Ahrefs' equivalent score, based largely on a site's backlink profile. Like DA, higher tends to be better. Looking at both DA and DR together gives you a more balanced picture than either alone.

Monthly organic traffic

Traffic may be the most important metric of all. A site can have a high DA/DR but little real traffic. A publisher with steady organic visitors is more likely to be a genuine, healthy site — and a link from it is more likely to send real referral visitors too.

Spam score

Spam score estimates how "spammy" a site looks. A low spam score is a good sign; a high one is a red flag that the site may be part of a link network or use manipulative tactics. On WeViaLinks you can filter by spam score so you only see clean publishers.

How to read them together

  • Solid DA/DR and real traffic and a low spam score = a strong, safe link.
  • High DA/DR but near-zero traffic = be cautious; it may be inflated.
  • High spam score = skip it, regardless of the other numbers.
  • Niche relevance to home services on top of good metrics = ideal.

Frequently Asked Questions

What is a good Domain Authority for a backlink?+

There's no single cutoff — it depends on your niche and competition. Use DA as a relative guide alongside traffic and spam score rather than chasing a specific number.

Is DA or DR more important?+

Neither alone tells the full story. Looking at both Moz's DA and Ahrefs' DR together gives a more balanced picture than either in isolation.

Why does a site's traffic matter for backlinks?+

Traffic shows the site is genuinely active and trusted by Google. A high score with little traffic can be inflated, and a link from it sends fewer real visitors.

What is a safe spam score?+

Lower is better. A low spam score suggests a clean profile, while a high one is a red flag that the site may use manipulative tactics — skip it.

Can a high-DA link still be bad?+

Yes. A site can have an inflated DA but no real traffic, an off-topic niche, or a high spam score. Always check all four metrics together.

How do I check these metrics before buying?+

On WeViaLinks, every listing displays DA, DR, traffic, and spam score upfront, so you can vet each publisher before you order.
