# Trust Flow

> Trust Flow is a link-quality metric that scores a site based on how closely its backlinks connect to a set of trusted seed sites.

**Trust Flow** is a link-quality metric that scores a website according to how trustworthy the sites linking to it are. Rather than counting links, it measures proximity to a curated set of trusted seed sites: the closer and more direct the connection between a page and those trusted sources through links, the higher its Trust Flow. It is a third-party metric, not an official search-engine figure.

## How Trust Flow works

The idea behind Trust Flow is that trust propagates through links. Starting from a manually reviewed set of highly reputable sites, the metric follows links outward, with trust diminishing over distance. A site that receives [backlinks](https://nodea.io/en/glossary/backlink) from pages only a step or two from those trusted seeds scores well, while a site linked mainly from obscure or low-quality pages scores poorly, even if it has many links. Trust Flow is usually read alongside a companion metric that reflects link quantity and influence, and the balance between the two is telling.

## Trust Flow in SEO strategy

Trust Flow is valuable because it captures quality rather than raw volume. A high link count paired with a low Trust Flow often signals spammy or artificial links, whereas a modest number of links from trusted sources tends to be far more beneficial. This makes the metric a useful guide for [link building](https://nodea.io/en/glossary/link-building): the goal is earning links from reputable, topically relevant sites rather than accumulating many weak ones. Trust Flow complements other measures such as [domain rating](https://nodea.io/en/glossary/domain-rating), giving a fuller picture of a link profile's health. It is worth remembering that these are estimates from external tools and only approximate how search engines actually weigh links. Still, as a practical proxy, Trust Flow reinforces a core principle of sustainable [SEO](https://nodea.io/en/glossary/seo): the quality and trustworthiness of the sites linking to you matter more than their number.

### Is Trust Flow an official Google metric?

No. Trust Flow is a third-party metric created by an SEO tool provider, not something Google publishes. It is a useful proxy for link quality, but it does not directly determine rankings.
