Domain Authority vs Domain Rating for Casino SEO

Domain Authority and Domain Rating are the two metrics casino SEOs quote most often — and misunderstand most often. Both try to estimate how strong a website is, but they come from different tools, use different scales in practice, and can both be gamed. This guide explains what each really measures and how to use them without being fooled.

What Domain Rating (DR) measures

Domain Rating is Ahrefs metric. It estimates the strength of a site backlink profile on a 0 to 100 scale, based largely on the quantity and quality of referring domains pointing to it. A higher DR generally means more and stronger backlinks. It is the metric most casino link vendors quote, which is why our tiers reference DR — but DR alone tells you nothing about traffic or relevance.

What Domain Authority (DA) measures

Domain Authority is Moz metric, also on a 0 to 100 scale, predicting how well a domain might rank based on its overall link profile. It is conceptually similar to DR but calculated differently and by a different tool, so the two numbers for the same site rarely match exactly. DA and DR are estimates by third parties, not signals Google itself uses.

The critical point: neither is a Google metric

This is what beginners miss. DA and DR are third-party approximations. Google does not use them. They are useful shorthands for comparing sites, but chasing a number for its own sake is a mistake. A DR 70 site with fake links and no traffic is worth far less than a DR 45 casino site with real visitors, as we stress in our guide on which metrics matter.

Both can be inflated

Because DA and DR are driven by backlinks, both can be artificially pumped with spammy links. Sellers know buyers filter by these numbers, so some inflate them deliberately. Always look behind the score: examine the referring domains, check for a natural link profile, and confirm the site has genuine organic traffic. A high number built on junk links is a warning sign, not a green light.

How to use DA and DR wisely for casino links

• Use them as a first filter, not a final verdict.
• Always pair them with real organic traffic and a healthy traffic trend.
• Check referring-domain quality behind the score.
• Prioritise relevance — a relevant lower-DR casino site often beats a higher-DR general site.

Which should you rely on?

For casino link buying, DR is the more commonly quoted metric and is a reasonable first filter, but the tool matters less than how you use it. Whether a vendor quotes DA or DR, the discipline is the same: treat it as one signal among several, verify it against traffic and relevance, and never buy on the number alone. That discipline sits at the heart of a sound link building strategy.

The takeaway

Domain Authority and Domain Rating are useful but imperfect third-party estimates of a site strength, calculated by Moz and Ahrefs respectively and not used by Google. Both can be inflated, so use them as a starting filter and always verify with real traffic, clean referring domains and topical relevance before buying a casino backlink. The number gets you in the door; relevance and traffic decide whether the link is worth it. Need help vetting? Request a free audit.
