Domain metrics describe different datasets and measurements. Some summarise links, others estimate visitors or record dates. Use them to organise auction research and support accurate sale descriptions, while keeping the underlying evidence and transaction terms separate.
A useful metrics record identifies provider, scope, check date and uncertainty. It does not turn a collection of numbers into a guaranteed price or performance result.
Distinguish scores from observations
Moz’s Authority Scoring Guide describes DA’s comparative role and separation from Google’s ranking calculations. Its PA whitepaper addresses page-level assessment.
Keep a domain score distinct from a score for a particular URL. Inspect significant links and old destinations before interpreting the result as a purchase benefit.
Understand link totals and Flow Metrics
Majestic’s glossary defines its Flow Metrics and link terminology. Backlinks and referring domains are different counts; repeated links from one website can produce a large total.
Check whether important source pages remain available, contain the link and discuss a relevant subject. Topical categorisation and score gaps can identify questions for review without delivering an automatic verdict.
Identify measured and estimated traffic
Ahrefs’ organic-traffic documentation describes a modelled estimate. It is not an exact visitor count and need not match owner-provided analytics.
Record source, period and channel. Request appropriate authorised evidence for current traffic claims, leaving unavailable records unverified. Estimated visitors cannot establish actual revenue.
The traffic-and-link workflow connects those checks.
Keep dates and other assets in context
A registration date and a first archived page capture concern different records. Neither proves uninterrupted operation, the same ownership throughout or current authority.
Social engagement can concern an account or content rather than the registration alone. Confirm what is included and check relevant transfer terms before describing it as a sale asset.
The registration-data guide explains administrative fields and their limits.
Build a consistent comparison table
| Field | Record beside it |
|---|---|
| Authority score | Vendor, domain or page scope and date. |
| Link count | Dataset and concentration observations. |
| Traffic | Estimate or measurement, period and channels. |
| History | Captured pages and evidence gaps. |
| Costs | Purchase charges and renewal commitment. |
Keep missing fields separate from confirmed zeros. Recheck material anomalies before submitting a binding bid, and compare the same scopes rather than mixing providers as if their scores were interchangeable.
Save the original export or report with its check date. If a seller supplies only a screenshot, establish the source and scope before copying its figures into your own comparison.
Connect the numbers to a decision
Assess naming fit, plausible uses, rights concerns and current acquisition terms outside the metrics. A higher score can justify closer inspection without justifying a larger price automatically.
The valuation guide helps build a range. Save a dated reason to reject, investigate or consider buying; that reasoning is the useful result of collecting metrics.
