Backlink Metrics
What are Backlink Metrics?
Backlink metrics are quantitative indicators that evaluate the quality and quantity of incoming links to a website. These metrics help SEO experts understand the link power of a domain and make strategic decisions for Link Strategy.
The Most Important Backlink Metrics
1. Domain Authority (DA)
Domain Authority is a metric developed by Moz that evaluates the strength of an entire domain on a scale from 0 to 100. It is based on several factors:
- Number of incoming links
- Quality of linking domains
- Age of the domain
- Link diversity
Important: Domain Authority is a relative metric - it shows strength compared to other domains, not absolute SEO power.
2. Page Authority (PA)
Page Authority evaluates the strength of individual pages based on:
- Incoming links to the specific page
- Quality of linking pages
- Internal linking
- Content quality
3. Trust Flow (TF)
Trust Flow from Majestic measures the trustworthiness of links:
- Based on seed sites (high-quality, trustworthy websites)
- Considers Reference Context
- Measures editorial quality
4. Citation Flow (CF)
Citation Flow evaluates the quantity of links:
- Number of incoming links
- Link volume
- Distribution of links
Trust Flow vs. Citation Flow: Typical ratios between TF and CF for different website types show the balance between quality and quantity of links.
5. Spam Score
The Spam Score identifies potential spam factors:
- Excessive external links
- Suspicious anchor texts
- Low content quality
- Unnatural link patterns
