Frequently Asked Questions
What is Domain Authority (DA) and how is it calculated?+
Domain Authority is Moz's proprietary metric (0-100 scale) predicting how well a website will rank on search engines. It's calculated using multiple factors: linking root domains, total backlinks, MozRank, MozTrust, and dozens of other signals. DA is comparative - your score means more when compared to competitors than in isolation.
Is Domain Authority a Google ranking factor?+
No, DA is not a Google ranking factor. It's a third-party metric created by Moz. However, DA correlates strongly with Google rankings because it measures many of the same signals Google uses (backlinks, domain trust, authority). High DA sites tend to rank better, but DA itself doesn't directly influence Google's algorithm.
What's a good Domain Authority score?+
DA is relative to your industry and competitors. Generally: 40-50 is average, 50-60 is good, 60-70 is very good, and 70+ is excellent. New sites start around 1-10. Focus on improving your DA relative to direct competitors rather than chasing a specific number. Beating competitors by even 5-10 points can provide significant ranking advantages.
How long does it take to increase Domain Authority?+
DA changes slowly as it's based on accumulated authority over time. Small improvements (1-5 points) can occur in 1-3 months with consistent link building. Significant gains (10+ points) typically take 6-12 months of sustained SEO efforts. Sudden jumps or drops usually indicate major link profile changes or Moz algorithm updates.
Why did my Domain Authority drop?+
DA drops happen for several reasons: competitors gained more authority (DA is relative), you lost quality backlinks, Moz updated their algorithm (affecting all sites), your site was penalized or de-indexed, or link velocity decreased significantly. Check your backlink profile for losses and compare against competitors to identify the cause.
How can I improve my Domain Authority?+
Focus on earning quality backlinks from authoritative, relevant sites. Strategies include: creating linkable content (research, tools, guides), guest posting on industry sites, building relationships with influencers, reclaiming broken links, fixing technical SEO issues, improving internal linking, and consistently publishing high-quality content. DA improvement is a long-term SEO investment.
What is the Backlink Health Score and how is it calculated?+
Our Backlink Health Score (0-100) analyzes your link profile quality using multiple factors: indirect link ratio (detects PBNs), nofollow ratio (quality indicator), link decay rate (deleted domains), and spam score. The algorithm penalizes red flags like >30% indirect links, >20% nofollow, or >10% deleted domains. Scores: 80+ = Excellent (A grade), 60-80 = Good (B grade), 40-60 = Fair (C grade), <40 = Poor (D-F grade). A low score indicates potential toxic backlinks or unnatural link patterns.
What does Link Quality Analysis show?+
Link Quality Analysis breaks down your backlink profile into three key ratios: Direct vs Indirect (healthy = 60%+ direct links from genuine sites, not link networks), Follow vs Nofollow (ideal = 70%+ follow links showing editorial trust), and Active vs Deleted (healthy = 85%+ active domains showing profile stability). Visual bars show your ratios with ✅ (good) or ⚠️ (warning) indicators. This helps identify link scheme patterns, low-quality sources, and natural vs artificial link building.
