Definition
Topical Trust Flow is an evolution of Majestic's classic Trust Flow that breaks down a site's authority into thematic categories. Rather than giving a single global score, it assigns a trust score for each theme (Sports, Business, Health, Education, etc.) based on backlinks received from reference sites in those domains. This metric is essential for link building because it evaluates a site's thematic relevance: a site with high Topical Trust Flow in 'Business/Marketing' will be more relevant for a link in digital marketing than a generic site with the same global Trust Flow.
Key Points
- Breaks down Trust Flow into thematic categories to evaluate link relevance
- Developed by Majestic, based on classifying millions of reference sites
- Essential for evaluating thematic coherence of a backlink profile
Practical Examples
Thematic backlink selection
A sports e-commerce site compares two sites: site A has TF 30 but TTF Sport of 5, site B has TF 22 but TTF Sport of 35. Site B is preferred for thematic coherence.
Link profile audit
Topical Trust Flow analysis reveals 60% of a cooking site's backlinks come from 'Gambling' and 'Adult' categories, signaling an artificial link profile to clean up.
