Domain Authority Concepts
Authority-style metrics estimate how strong a domain may be compared with others. They are created by SEO tools, not by Google as public official scores.
Backlinks matter
Links from relevant and trusted websites can help a site build reputation. Low-quality or manipulative links may create risk instead of value.
Topical relevance
A domain can be strong in one topic and weak in another. Relevance often matters more than a broad numerical score.
Use carefully
Authority metrics are useful for comparison, but content quality, search intent, technical health, and user satisfaction still matter.
