Authority metrics
DA and DR are useful shorthand and terrible purchasing criteria. Buying high authority backlinks well means knowing exactly what the scores measure and what they hide.
Overview
Domain Authority is Moz's model. Domain Rating is Ahrefs'. Both estimate the strength of a site's link profile on a logarithmic 0 to 100 scale, and both are third-party predictions, not Google data. Google has said repeatedly that it uses no metric called domain authority.
The scores correlate with ranking power, which is why everyone quotes them. The trouble starts when the score becomes the product: vendors sell high authority backlinks by the metric alone, from sites whose number is inherited, inflated, or irrelevant to your market. The fix is not ignoring metrics. It is reading them alongside what they cannot see.
What DA counts as high authority?
Above 60 is the common shorthand, but the honest answer is contextual. In a tight B2B niche, the most authoritative trade title might sit at DA 48 and still be the best link available. We treat 40 as the floor and judge everything above it on traffic and relevance.
Service detail
Both metrics summarize a site's inbound link graph: how many referring domains point at it and how strong those domains are. That is all. The logarithmic scale means moving from 70 to 80 takes far more link equity than moving from 20 to 30, which is why high scores are scarce and why sellers lean on them so hard.
Neither metric knows whether a site has readers, whether its traffic is rising or collapsing, whether it quietly sells guest posts, or whether the page your link sits on is even indexed. A domain can hold a DA of 75 for years after its editorial standards die. The score checks the skeleton; you still have to check the pulse: organic traffic in Ahrefs or Semrush, ranking keywords, and recent, human-written content.
A DA 45 trade publication read by your exact buyers usually does more than a DA 90 general-news aggregator. The trade title's pages rank for your commercial terms, its audience overlaps yours, and its citation reads as a topical endorsement. Relevance concentrates value; raw authority dilutes it across every subject the big site covers. What makes any single link genuinely good is a page-level question, unpacked under editorial backlinks.
Campaigns blend tiers deliberately. National press (DA 80 to 95) supplies trust and reach. Specialist and trade outlets (DA 40 to 70) supply relevance and commercial-term rankings. The result is a portfolio of high authority backlinks spanning DA/DR 40 to 95 with an average of DA 82, and the monthly report shows each link's metrics so the mix is never a mystery.
Run three checks on any promised placement: the domain shows meaningful organic traffic, the linking section is indexed and human-edited, and the score is broadly consistent between Moz and Ahrefs, since a large gap often signals manipulation. The full sequence is in the backlink quality checklist and takes about five minutes per domain.
Managed delivery
You do not need to manage journalist outreach, write the pitch, or chase live URLs. Send the site and target pages, and the campaign desk handles the rest.
We compare your referring-domain profile against the sites outranking you, tier by tier.
National press for trust, trade titles for relevance, weighted to your keyword targets.
Data stories tend to land national coverage; expert commentary wins the specialist press.
Every domain passes traffic and indexation checks before it counts toward your minimum.
Questions
Above 60 is the common shorthand, but the honest answer is contextual. In a tight B2B niche, the most authoritative trade title might sit at DA 48 and still be the best link available. We treat 40 as the floor and judge everything above it on traffic and relevance.
They disagree in useful ways. DR reacts faster to new links; DA models more signals and moves slower. We check both, and a big spread between them usually means a profile built quickly, which deserves a closer look before anyone pays for a placement.
Every placement lands within the DA/DR 40 to 95 range, and the report shows each link's metrics. We do not promise a specific score per link because editorial coverage cannot be pre-ordered, but the portfolio average across our work is DA 82.
If the site sells placements openly, its high score can coexist with a link profile Google has already discounted. One bad buy rarely triggers a penalty, but you will have paid a premium for a link that passes nothing.
