💡 Recommendations to Improve Authority
ⓘ Authority scores are estimated based on domain signals. For precise DA/PA scores, use Moz's official tools. These estimates are for guidance only.
What Is Website Authority and Why Does It Matter?
Website authority — most commonly measured as Domain Authority (DA) — is a score that predicts how likely a website is to rank in search engine results pages. Developed by Moz, DA ranges from 1 to 100. The higher your score, the stronger your domain's ability to compete for competitive keywords in Google.
While DA is not a Google ranking factor, it strongly correlates with organic search performance because both are driven by the same underlying signals: the quality and quantity of backlinks pointing to your domain. Understanding your authority score tells you where you stand relative to competitors and how much link building work is needed to outrank them.

How to Increase Domain Authority
Domain Authority grows when you earn high-quality backlinks from authoritative websites. The most effective link building strategies are: Guest posting on reputable industry publications — a single link from a DA 70+ site can move your DA measurably. Linkable asset creation — original research, free tools, comprehensive guides, and industry data attract natural backlinks. Digital PR — pitching journalists and bloggers with newsworthy stories. Broken link building — finding broken links on high-authority sites and offering your content as a replacement. Directory listings — getting listed on industry directories, Clutch, Trustpilot, and Google Business Profile all contribute to authority signals.
DA vs Google PageRank: What Is the Difference?
Google PageRank is Google's internal algorithm for assessing page importance — it has not been publicly updated since 2016. Domain Authority is Moz's publicly available approximation of overall domain strength. They measure similar things (backlink quality and quantity) but are calculated differently. For practical purposes, DA is the best publicly available proxy for how Google likely views your domain's authority.
Frequently Asked Questions
Domain Authority is a 1–100 score developed by Moz that predicts how likely a website is to rank in search engine results. It is calculated based on the number and quality of links pointing to a domain. Higher DA scores correlate with stronger organic search performance, but DA is a predictive metric — not a Google ranking factor.
DA scores are relative to your competition. New websites start at 1–10. Established local businesses typically score 20–40. Niche authority sites range from 40–60. Major media sites score 70–90+. The most important comparison is against your direct competitors — not against large media outlets with decades of backlinks.
Domain Authority grows by earning high-quality backlinks. The most effective methods: guest posting on reputable industry sites, creating linkable assets (research, free tools, guides), digital PR outreach, getting listed in industry directories, and building brand mentions. DA grows slowly — expect 6–12 months to see meaningful changes.
No. Domain Authority is a Moz metric, not a Google metric. Google uses its own internal calculations of website quality and authority. However, DA correlates strongly with Google rankings because both are influenced by the same factor: quality backlinks. Sites with high DA tend to have many quality backlinks, which Google values highly.
Moz updates Domain Authority scores approximately once per month. Significant changes in your backlink profile will be reflected in the next monthly update. Google crawls and indexes backlinks continuously, so the impact of new links on actual rankings may appear before DA scores update.
Domain Authority (DA) measures the ranking strength of an entire domain. Page Authority (PA) measures the strength of a specific individual page. DA is influenced by the overall backlink profile of the domain. PA is influenced by links pointing specifically to that individual URL.
Spam Score is a Moz metric (0–100%) indicating the percentage of sites with similar features that were penalized or banned by Google. A Spam Score above 30% warrants investigation. High Spam Score can result from low-quality backlinks, thin content, aggressive ad placement, or other practices that correlate with penalized sites.
