What is Domain Authority and what it means

Domain Authority

What is a Domain Authority?

The authority a website is not a fixed category. The term has emerged in the SEO industry over time and roughly describes a website that is a reference for a specific topic. For example, the page selfhtml.org (http://de.selfhtml.org/index.htm) (or its successor: http://wiki.selfhtml.org/wiki/Startseite) is an authority for HTML code and programming.

In the SEO industry, the terms "authority", or "link authority" can have different meanings. In general, the “authority” of a website is a mixture of different metrics that distinguish this website from other websites. Furthermore, a Link authority as well as a single subpage or document. In this case one speaks of PageAuthority or LinkAuthority.
MOZ provides a metric for the DomainAuthority in its Open Site Explorer. http://moz.com/learn/seo/domain-authority

OnPage factors that can influence the authority of a website:

  • Keywords in the titles of the URLs
  • Amount of keywords and amount of URLs
  • Headings with important keywords
  • Site architecture and internal links
  • Alt texts

OffPage factors

  • Many domain links compared to the surrounding area.
  • Links were not created all at once, but organically over time.
  • The links point explicitly to various sub-pages and come from high-quality, trustworthy websites.
  • Many mentions in forums, question-and-answer portals or social media.
  • Outgoing links refer to high-quality websites and offer the user meaningful, further information.
  • If a well-known author writes for a website, this can also increase DomainAuthority.
  • Good social signals

An authority is usually a website that has grown naturally and has made "a name" for itself over time. The older a domain is, the higher the chance it will become an authority. But that does not rule out the case that a relatively new and young site can quickly become an authority.
