Co to jest Domain Authority?
Szybka definicja
Domain Authority (DA) to wynik rankingu SEO opracowany przez Moz, który przewiduje prawdopodobieństwo pojawienia się witryny w wynikach wyszukiwania w skali od 1 do 100.
Domain Authority is a metric created by Moz, an SEO software company, to estimate a website's ranking potential. It analyzes factors like the number and quality of backlinks pointing to a domain to generate a score from 1 to 100, with higher scores indicating greater ranking ability.
It's important to understand that Domain Authority is not a Google ranking factor. Google does not use Moz's DA score in its algorithm. However, DA is useful as a comparative tool to evaluate the relative strength of websites. It helps SEO professionals prioritize link building targets, assess competitors, and track their site's authority over time.
DA is calculated using a machine learning model that considers linking root domains, total number of links, and other factors. New websites start with a DA of 1, while the most authoritative sites like Google, Facebook, and Wikipedia have DAs close to 100. Most small business websites fall in the 20-40 range.
Similar metrics exist from other SEO tools: Ahrefs has Domain Rating (DR), SEMrush has Authority Score, and Majestic has Trust Flow. While the specific calculations differ, they all attempt to measure the same concept: how authoritative a domain is based on its backlink profile.
Dlaczego jest ważne
Domain Authority gives you a benchmark to measure your website's competitive position. If your DA is 25 and your top competitors are all above 50, you know you need to significantly invest in link building before you can compete for their keywords.
It also helps you evaluate link building opportunities. Getting a backlink from a DA 70 website is far more valuable than one from a DA 10 website. Understanding this helps you focus your outreach efforts where they'll have the most impact.
