Metric glossary

What the SEO numbers mean.

Moz

Domain Authority (DA): 0–100. Moz's link-strength estimate for the whole domain.
Page Authority (PA): 0–100. Same idea, scoped to the root page only.
Spam Score: 0–17. Moz's flag-risk indicator. Lower is better.
MozTrust: 0–10. Proximity in the link graph (the web of sites + the hyperlinks between them) to a curated seed of trusted sites — gov, edu, established brands. Inbound links from trusted neighbours raise it.
MozRank: 0–10. Log-scale link popularity (PageRank-like).
External links: Total inbound links Moz has indexed.

Majestic

Trust Flow (TF): 0–100. Link-trust score from Majestic's seed-set algorithm — same idea as MozTrust, different vendor.
Citation Flow (CF): 0–100. Raw link-volume influence. Pair with TF: high TF + high CF = strong, balanced.
Referring Domains: Unique domains linking here. Diversity matters more than raw backlink count.
Total backlinks: Total inbound link count, including duplicates from the same site.
Referring IPs / Subnets: Unique IPs and class-C subnets of linking sites — rules out single-host spam farms.
Edu / Gov links: Backlinks from .edu and .gov domains. Hard to fake; high signal.

Topical Trust Flow

Top-3 categories Majestic detects in the linking pages. Tells you what kind of sites already point at this domain — a "News/Newspapers 14" pill means roughly 14% of the trust signal flows from news sites.
