What the experts say
Google Search Console provides the most accurate backlink data for your own site, but it's not designed for competitive analysis.
Domain Authority was created to help compare sites, but it's often misused as an absolute quality score.
Frequently asked questions
How accurate are free backlink checkers?
Limited—most show sampled data or outdated indexes. Google Search Console is the only free tool with direct Google data, but lacks competitor insights.
Can I trust Domain Authority scores?
Moz's DA and similar metrics are directional indicators, not Google rankings factors. Use them for relative comparisons only.
How often do tools update their indexes?
Ahrefs updates daily; Majestic weekly; others vary. Freshness matters most for new link detection.
What's the minimum viable backlink toolset?
Google Search Console (free) + Ahrefs or Semrush ($100+/month) covers most needs. Add Majestic for historical link analysis if budget allows.
