Domain SEO Metrics Explained for Buyers

Metrics compress large datasets into convenient scores. That is useful for sorting candidates, but due diligence starts when you open the data behind the score.

Majestic Flow Metrics

Majestic describes Trust Flow as a quality-oriented link metric and Citation Flow as a measure related to link influence or quantity. Majestic itself recommends using Flow Metrics as part of broader link analysis.

Moz Domain Authority

Domain Authority is a proprietary comparative score, not a Google metric. Use it to compare domains within the same tool and data context rather than as a promise of rankings.

Semrush Authority Score

Semrush says Authority Score combines link power, estimated organic traffic and spam-related factors. That makes it another useful screening model, not a substitute for opening links and history.

Build a metric stack, not a metric religion

Use several signals to find candidates where the evidence appears consistent. If one score disagrees sharply with the rest, investigate the cause instead of averaging the numbers away.
