Trust is fundamental to backlink quality. A link from a trusted source carries weight; a link from an untrustworthy source may carry risk. This guide explains how to identify trust signals in potential link sources.
What Trust Means for Backlinks
Google's Trust Considerations
While Google doesn't publish its trust metrics, their documentation and patents suggest they consider:
- Link distance from trusted seed sites: How many steps from known authoritative sites
- Site reputation: Historical behaviour and quality signals
- Pattern matching: Whether link patterns suggest manipulation
- Content quality: Whether the site produces genuine value
Why Trust Matters
Links from trusted sources:
- More likely to pass ranking value
- Less likely to trigger scrutiny
- Provide sustainable benefit
- Enhance your site's reputation
Links from untrusted sources:
- May pass little or no value
- Could trigger algorithmic devaluation
- Might require disavowal
- Create ongoing risk

Trust vs Authority
They're Related but Different
Authority: How much ranking power a site has Trust: How legitimate and reliable the site is
High authority, low trust: Manipulated domains with inflated metrics but no real legitimacy
Low authority, high trust: New legitimate businesses, small but genuine publications
Prioritising Trust
When choosing between:
| Option A | Option B | Choose |
|---|---|---|
| High authority, low trust | Lower authority, high trust | B |
| High trust, low relevance | High trust, high relevance | B |
| Moderate authority, high trust | High authority, moderate trust | Consider both |
Trust provides a floor of safety. Authority without trust creates risk.
