Domain Authority can help organise an expired-domain shortlist, but it cannot tell you what an acquisition will do for your website. It is a score created by Moz, using its own data and model. Google does not use Moz’s DA score to determine rankings.
That distinction changes the buying decision. A high-DA domain deserves investigation of the evidence behind the number; it does not deserve a purchase simply because the number is high.
What the score means for an expired domain
Moz’s Authority Scoring Guide describes DA as a comparative prediction and cautions against treating it as an absolute quality grade. The guide also states that DA is not used in Google’s ranking calculations. Use it to compare candidates from the same source, then investigate their links and previous use.
An expired candidate may carry a score based on links discovered during its former life. That is evidence about a vendor’s picture of the domain, not proof that the links are still present, relevant or capable of benefiting your planned content. A seller’s old screenshot adds another uncertainty: the current data may differ.
DA also does not establish registration availability, ownership rights or a fair price. Keep those checks in separate columns. The deleted-domain workflow explains why an expiry date alone is insufficient to establish that you can register the name.
Use DA to decide what to inspect first
Begin with names that fit your intended subject and budget. Retrieve current metrics consistently and record the provider, date and domain scope. Avoid mixing a root-domain assessment with a single-page assessment or comparing scores from different vendors as though they were interchangeable.
Set a working filter only if it helps manage the list. A threshold such as DA 20 is an administrative choice for a particular research exercise, not a quality standard. Keep especially suitable names visible even when they fall below it. Otherwise, a filter can discard a useful brand while retaining an irrelevant domain with stronger historical links.
For broader screening, the domain metrics guide combines authority scores with link counts, topic and manual inspection. The questions you ask after filtering matter more than the threshold itself.
Inspect the links that support the score
Open a sample of linking pages rather than relying entirely on aggregate totals. Review important source pages, repeated anchors, heavily linked old URLs and any clusters that appear unrelated to the domain’s subject.
- Is the linking page still available, and does it still contain the link?
- Does the link make editorial sense within its surrounding text?
- Do many recorded links come from only a few websites?
- Are the linked destinations useful topics you could address with original work?
- Does the link history agree with archived versions of the website?
Record your findings and unresolved questions. A missing page is an uncertainty, not automatic evidence of spam. Conversely, an impressive score cannot excuse a pattern of misleading content or unrelated promotional links.
Compare two candidates without buying the score
Imagine a shortlist for a walking-route publication. Candidate A has DA 42, but the strongest recorded links concern an unrelated financial service and several source pages are gone. Candidate B has DA 24, a readable outdoor name and relevant links to former trail guides that remain visible.
These are hypothetical candidates. B earns further research because its name and observed history fit the project, despite its lower score. A requires an explanation for the mismatch. Neither is a confirmed purchase: renewal costs, trademarks, acquisition terms and the wider content history still need checking.
Handle search-policy and access limits honestly
Google’s expired-domain abuse policy concerns acquisitions repurposed primarily to manipulate rankings with little useful value for users. An expired domain can support a legitimate project, but neither its age nor DA justifies an unrelated, low-value site built for search manipulation.
If you can obtain authorised Search Console access from the current owner, review Google’s Manual actions report. You cannot use it to inspect an arbitrary unowned domain. An empty public search result or a low third-party spam score is not a substitute for that report, and absence of a manual action does not guarantee future performance.
Finish with a written decision: suitable name, relevant observed links, acceptable history, confirmed purchase route and affordable costs. For sourcing candidates, use the DA and PA research guide. Treat DA as the start of a closer look, while making the final decision from evidence you can explain.
