Domain metrics help you decide which expired names deserve manual investigation. Their main value is reducing a long list to a manageable research queue. They do not certify a clean history, establish availability or predict the traffic your new website will receive.
Use a consistent set of measurements, understand what each describes and look for questions hidden by the totals. The best candidate is the one you can justify for your project after inspecting the evidence.
Separate domain scores from page scores and counts
Start by identifying the provider and scope of each field. A root-domain score, a homepage score and a count of links are different observations. Combining them can be useful; treating them as interchangeable is misleading.
| Metric | What it helps you examine | What to check next |
|---|---|---|
| Moz Domain Authority | Relative ranking potential in Moz’s model. | Relevant observed links and comparisons from the same provider. |
| Moz Page Authority | Relative ranking potential of a specific page. | The exact URL and the links pointing to it. |
| Majestic Trust Flow | A quality-oriented link signal within Majestic’s model. | Source pages, relevance and link context. |
| Majestic Citation Flow | Link influence with an emphasis on quantity and the link network. | Concentration, repetition and the balance with other evidence. |
| Referring domains | The number of distinct domains linking in a dataset. | Whether the sources are live, independent and relevant. |
| Backlink count | The number of recorded links in a dataset. | Whether large totals come from repeated site-wide links. |
Moz’s Authority Scoring Guide explains DA’s comparative role and its separation from Google’s ranking calculations. Its Page Authority whitepaper explains the page-level distinction. Majestic’s glossary defines its Flow Metrics and topical categories. These are vendor models, not universal grades for domain quality.
Make comparisons consistent
Record the source, collection date, scope and index where the service exposes one. Compare root domains with root domains and page URLs with page URLs. Avoid drawing a trend from numbers collected by different services without checking how their definitions differ.
A zero, blank or failed lookup can mean different things. Keep missing data separate from a confirmed zero rather than converting every empty cell to the lowest score. Recheck important anomalies before rejecting a name or calling its history clean.
Start with topic and naming fit. Metrics do not make an unrelated name suitable for your intended site. The DA and PA sourcing guide can help build a candidate list; apply your own project requirements before spending credits on every result.
Look for patterns that merit inspection
Thousands of backlinks from a few domains may reflect repeated navigation or footer links. That is a reason to inspect concentration, not an automatic spam verdict. Likewise, a gap between Trust Flow and Citation Flow should prompt questions about the observed sources; there is no universal ratio that confirms a good acquisition.
Compare topical categories with archived content and your proposed use. If a domain’s former articles concerned cycling but most current anchors promote unrelated products, investigate when that change occurred. Review multiple historical snapshots because one date may miss a change of ownership or a compromised website.
Our Domain Authority guide examines why a large score can obscure weak or irrelevant evidence. Use numerical filters to prioritise inspection, and leave room to revisit a strong name that a filter excludes.
Turn a metrics shortlist into a research record
For each finalist, inspect a selection of important linking pages and the old URLs they target. Check whether links remain present, how the source discusses the destination and whether you could provide genuinely relevant original content for the linked subject.
In a hypothetical comparison, Candidate A has 12,000 backlinks from 18 referring domains. Candidate B has 900 backlinks from 110 referring domains. B’s wider spread makes it worth investigating first if both names fit the project. It does not prove B is better: the sources could still be irrelevant, unavailable or connected to each other.
Give each name a status such as investigate, reject or consider purchasing. Add a reason and a next action. A useful note might record that the name fits the project but its three most important source pages still require verification.
Complete the checks that metrics cannot supply
Confirm current registration or auction availability, purchase terms, renewal costs and possible trademark conflicts. Do not interpret an expiry listing or absent DNS record as proof that registration is open. The deleted-domain workflow helps separate those stages.
Finally, assess the intended use against Google’s expired-domain abuse policy. Buying a historical link profile does not justify repurposing a name primarily to manipulate rankings with little useful content. A sound decision brings together a suitable name, relevant evidence, affordable costs and a credible plan for serving readers.
