TrustFlow Replaces Google's PageRank as a Major SEO Signal
With Google retiring public toolbar PageRank, digital marketers rely on Majestic's Trust Flow and Citation Flow metrics to evaluate backlink quality and domain authority.
The Demise of Public PageRank
For years, Google's green toolbar PageRank score (0 to 10) dictated link value. However, because public scores encouraged widespread link buying and manipulative blog spam, Google ceased updating public toolbar PageRank, leaving webmasters in the dark.
Understanding Trust Flow vs. Citation Flow
Majestic SEO stepped forward with a sophisticated dual-metric framework based on link neighborhood analysis:
- Citation Flow (CF): A score measuring link quantity and link volume power, regardless of source credibility.
- Trust Flow (TF): A score evaluating link quality based on proximity to trusted, human-vetted seed websites (such as universities, government portals, and major news outlets).
The Crucial Trust Ratio Formula
Evaluating raw numbers alone can be misleading. Savvy SEOs calculate the Trust Ratio by dividing Trust Flow by Citation Flow (TF / CF):
- Ratio > 0.8: Exceptional, highly authoritative domain with clean editorial links.
- Ratio between 0.4 and 0.8: Healthy, natural profile standard for established businesses.
- Ratio < 0.4: Warning sign of link spam, directory blast submissions, or low-quality scraped links.
Focus on Topical Trust Flow
Google evaluates semantic topical authority. Earning links from domains that share your specific industry classification carries far greater algorithmic weight than generic high-volume links.
