Trust Flow vs Citation Flow: What They Mean for SEO in 2026
Trust Flow vs Citation Flow: What They Mean for SEO in 2026
Trust Flow and Citation Flow are Majestic's two core metrics. They measure different properties of a backlink profile, and their ratio reveals more about domain quality than either number in isolation.
Trust Flow as a Quality Signal
Trust Flow (TF) measures the trustworthiness of a backlink profile based on proximity to Majestic's seed set — approximately one million trusted URLs from media outlets, government domains, and established editorial sources. The logic: a site linked from a major national newspaper sits closer to the seed set than one linked from a random directory.
TF does not weight volume. Three links from high-trust sources can produce TF 20, while 500 links from low-trust sources produce TF 5. For expired domain evaluation, TF is the best available proxy for the question: "did this domain earn real editorial links, or were they manufactured?"
Minimum thresholds: TF ≥ 15 for tier 2 PBN use, TF ≥ 20 for tier 1 direct links to money pages, TF ≥ 25 for competitive tier 1 campaigns.
Citation Flow as a Volume Signal
Citation Flow (CF) measures link volume without regard to source quality. High CF with low TF means high volume from sources far from the seed set — typically spam directories, blog comment networks, or cross-linked schemes.
CF is not useless — it provides scale context. TF 15 with CF 20 (ratio 0.75) is a clean, small profile. TF 10 with CF 50 (ratio 0.2) is a high-volume spam profile. Without CF, you cannot tell whether TF 15 represents a domain with 200 links or 5,000 links.
TF:CF Ratio
The ratio is the fastest quality filter from Majestic:
- ≥ 0.5: healthy, editorial-leaning profile — proceed to detailed review
- 0.3–0.5: acceptable quality, but investigate the anchor mix
- < 0.3: red flag — investigate heavily before any purchase decision
- > 0.9: very few, very high-quality links — check referring domain count; may be too thin for practical use
Apply ratio benchmarks in context. Forum-heavy niches have naturally lower TF:CF ratios because forum links inflate CF without raising TF.
Topical Trust Flow
Majestic breaks Trust Flow into categories — Gambling, Sports, Finance, Technology, etc. The category distribution tells you what kind of authority the domain has, not just how much.
For iGaming PBN domains: top category should be Gambling (ideally > 50%) or Sports (> 40%). A domain with TF 25 but top categories in unrelated verticals contributes topically irrelevant equity — diluted before reaching the money page.
Benchmarks by Domain Use
| Use case | TF minimum | TF:CF minimum | Topical alignment |
|---|---|---|---|
| Tier 1, competitive geo | 25+ | 0.5 | Niche-specific ≥ 50% |
| Tier 1, emerging market | 20+ | 0.45 | Niche-specific ≥ 40% |
| Tier 2 amplification | 10+ | 0.35 | Less critical |
| Redirect play | 25+ | 0.55 | Critical — mismatch reduces transfer |
False Positives
TF 30 with all links from a single high-trust source is single-source dependency — lose that one source and TF drops significantly. Cross-check TF with referring domain count: TF 30 with RD 200 is distributed and stable; TF 30 with RD 8 is fragile.
Majestic Historic Index: compare TF from 12 months ago to current. Stable or growing TF signals a maintained profile. Declining TF signals links being removed or devalued.
