Editor's Insight
The biggest link building mistake is mass outreach with generic templates. Personalized emails get 3-5x higher response rates. Spend 5 minutes researching each prospect and mention something specific about their site.
Link Quality Metrics Explained
Domain Rating (DR) – Ahrefs
- 0-20: Low authority
- 21-40: Medium authority
- 41-60: Good authority
- 61-80: High authority
- 81-100: Exceptional authority
Domain Authority (DA) – Moz
Similar scale to DR. Most sites are DA 20-40.
Trust Flow (TF) – Majestic

Ideal Ratio: TF should be close to CF (Citation Flow).
Common Link Building Mistakes
Mistake #1: Buying Links
Risk: Google penalty, wasted money
Fix: Build links through outreach and content
Mistake #2: Ignoring Relevance
Fix: Prioritize links from topically relevant sites
Mistake #3: Anchor Text Over-Optimization
Fix: Use varied, natural anchor text (brand, URL, generic)
Mistake #4: Not Disavowing Toxic Links
Fix: Monthly toxic link audits and disavow
Data-Driven Insights
Insight #1: Quality Over Quantity
10 DR60+ links increase rankings more than 100 DR20 links.
Insight #2: Link Velocity Matters
Gaining 50 links in one week looks unnatural. Aim for steady growth.

A DR40 link from a relevant site outperforms a DR70 link from an irrelevant site.
