DA — Domain Authority (0–100): Moz's prediction of how well the whole domain ranks. Higher is stronger. Logarithmic — 40→50 is much harder than 10→20.
PA — Page Authority (0–100): same idea, but for the single page/URL rather than the whole domain.
DR — Domain Rating (0–100): backlink-profile strength (Ahrefs-style). Higher = more / stronger links pointing in.
Spam Score (0–100): % of similar sites that were penalised or banned. 25–49 = caution, 50+ = high risk — avoid for links/PBN, they can drag you down.
Org Traffic: estimated monthly organic search visits. 0 usually means no ranking keywords (fresh, deindexed, or dead domain).
Rule of thumb for a link / expired domain: want high DA/DR, low Spam Score (ideally under 5), and non-zero Org Traffic. exedu.cn (DA 8 / Spam 79) is the opposite — low authority and dangerously spammy.
Score & ★ Rating (auto): a 0–100 quality score computed from the metrics —
Org Traffic weighted highest, Spam Score as a gate (50+ is disqualified; 30+ heavily penalised),
and DA/DR/PA secondary (DA & DR over PA). Rows scoring well with low spam and real traffic get a
gold ★Recommended mark and highlight. Sort by Score to bubble the best domains to the top.
How to read the Rating column:★★★★★ top pick · ★★★★ strong · ★★★ decent ·
★★ weak · ★ poor · – not suitable (skip it).
More stars = better overall quality, judged mostly on real organic traffic and a low spam score — high DA/DR alone won't earn stars if traffic is 0 or spam is high.
A gold ★ next to the domain flags the Recommended ones worth using.
