What is TF (Trust Flow) in SEO?
TF stands for Trust Flow, a metric developed by the SEO tool Majestic.
It measures the trustworthiness and quality of a website based on the quality of the websites linking to it.
Scale: 0 to 100
-
Higher TF = More trusted website
-
Lower TF = Weak or spammy backlink profile
✅ How Is Trust Flow (TF) Calculated?
-
Majestic has a list of highly trusted seed websites (like government, educational, and big brand sites).
-
If your website is linked to directly or indirectly by those trusted sites, your TF increases.
-
Links from relevant, authoritative sites matter more than just quantity.
Example:
A link from harvard.edu boosts your TF more than 100 low-quality blog links.
📊 TF Score Meaning Table (0–60)
| TF Score | Level | What It Means |
|---|---|---|
| 0 – 10 | Very Low | Weak trust; spammy or poor-quality backlinks. |
| 11 – 20 | Low | Some trust signals, but still early-stage authority. |
| 21 – 30 | Moderate | Average site; some quality backlinks are present. |
| 31 – 40 | Good | Trusted site; links from reputable sources exist. |
| 41 – 50 | Strong | High trust; your site is considered reliable in its niche. |
| 51 – 60 | Very Strong | Very high-quality backlink profile; close to elite-level trust. |
🔄 TF vs CF (Citation Flow)
| Metric | Meaning | Focuses On |
|---|---|---|
| TF | Trust Flow | Link quality and trustworthiness |
| CF | Citation Flow | Link quantity (regardless of quality) |
✅ Best Practice:
High TF with balanced CF is good. If CF is high but TF is low, it could mean your backlinks are spammy or low-quality.
