Ahrefs DR, Moz DA, and Majestic TF for Brazilian Sites

Ahrefs Domain Rating, Moz Domain Authority, and Majestic Trust Flow each measure a different slice of the link graph. On Brazilian sites they often disagree, not because the tools are broken, but because the referring neighbourhoods, language clusters, and historical link patterns differ from English-heavy corpora those tools were tuned on.

Buying Brazilian placements by a single score is overrated. Use the three together, then confirm with traffic and a human read. That is the same discipline behind how we evaluate Brazilian publisher quality.

Metrics are useful when they narrow a list. They become harmful when they become the product. Your report should explain why a domain cleared the bar, not only that DR cleared forty.

What each score actually measures

Ahrefs DR estimates relative backlink strength on a logarithmic scale. Moz DA estimates the likelihood a domain will rank well based on Moz's link index. Majestic TF estimates how trustworthy a domain looks based on the quality of sites that link to it, often paired with Citation Flow for volume context.

None of them measure Brazilian reader engagement. None of them know if the homepage is a real publication. They are proxies. Treat them like credit scores: useful, incomplete, and easy to game if nobody looks at the underlying behaviour.

DR responds heavily to link quantity and referring domain strength in Ahrefs' graph. DA blends Moz's view of link equity and other factors in their model. TF rewards links from hosts Majestic already trusts. A site can farm one of those ideas more easily than all three at once, which is why the trio matters.

Screenshot hygiene matters. Tools update. Scores move. Save the date with the metric when you approve a domain so nobody re-litigates a buy six months later with a different number.

Why Brazilian sites often look uneven across tools

Brazilian publishers can show a healthy DR with a softer DA, or a respectable TF with a middling DR, depending on who has linked them over time. Local news and regional portals sometimes look quieter in global tools than their real influence suggests. Contributed-post networks can look louder than their influence deserves.

Index coverage differs too. A site with mostly Brazilian referring domains may be sampled unevenly across vendors. When scores diverge wildly, open the referring domain reports. Look for footprints: identical guest-post templates, sudden spikes, or neighbourhoods full of expired domains. Divergence is a prompt to investigate, not a reason to average the three numbers and move on.

Language clusters play a role. Portuguese web neighbourhoods are smaller than English ones in many indexes. That can compress scores for honest local publishers and inflate scores for networks that collected international spam links. Always pair the score with the archive language and audience.

Aged .br domains with wiped content are another uneven case. Historical links can leave residual metrics while the live site is a thin shell. Judge the live site. History without readers is not a publisher.

Floors that work for editorial placements

For commercial editorial in Brazil, a practical starting band is Ahrefs DR 40 to 60, Moz DA in a similar neighbourhood, and Majestic TF that is not stuck near the floor while Citation Flow looks inflated. Mid-tier placements in that band often price at $150 to $450 depending on niche and edit standard. National news and top trade titles sit above that.

Local campaigns can go lower on raw DR when the host is a real city or state publisher with clean outbound links. A DR 32 regional portal with engaged readers beats a DR 55 thin blog that only ranks for its own guest-post URLs. Floors are filters. They are not a substitute for judgment.

Set different floors by publisher type in your brief. News, trade, regional, and niche vertical should not share one lazy cutoff. If you force every host above DR 50, you will overpay for vanity and miss regional titles that move local leads.

Revisit floors when pricing shifts. When mid-tier editorial drifts above $450 in competitive niches, raise quality expectations rather than chasing cheaper lookalikes. Cheaper usually means thinner outbound neighbourhoods.

When a modest DR beats an inflated DA

Inflated scores show up when a site has collected reciprocal or network links that one tool weights generously. If DA looks heroic while DR and TF look ordinary, and the archive is wall-to-wall sponsored posts, trust the archive. The same goes in reverse. A modest DR on a long-running Brazilian trade magazine with named journalists is usually the better buy.

Exact-match anchors will not fix a bad host. They make a bad host easier to pattern-match later. Keep anchors natural and let the domain quality do the heavy lifting.

Ask vendors for referring-domain samples, not only a DR badge. If they cannot explain why the score looks strong, you are buying a badge. Prefer sellers who talk about audience and section fit first.

A modest DR with real Brazilian traffic and clean outbound is also easier to defend in a client meeting. Inflated DA on a thin host only looks good until someone opens the homepage on a shared screen.

How we combine scores with traffic and outbound checks

Our pass rule is boring on purpose:

• Metric band across DR, DA, and TF
• Organic traffic floor appropriate to the niche
• Outbound density that looks editorial, not retail
• Brazilian Portuguese content with a real beat
• No PBN or thin-site footprints

Fail the outbound or language check and the domain is out even if DR looks pretty. That is also why we publish a hard line on PBNs and thin sites in Brazil. Metrics without those checks are how average campaigns buy screenshots.

If you want a shortlist already filtered this way, see our Brazilian market link acquisition process, check pricing, or contact with your niche and target metric band. We would rather send fewer URLs than defend a chart that does not survive a homepage visit.

Teach stakeholders the same rule. When leadership asks why you passed on a DR 70 bargain, show the outbound neighbourhood and the empty archive. Metrics become healthier the moment the team agrees that a single score is never enough for Brazilian editorial buys.

Re-check approved domains every quarter. Scores drift, outbound habits change, and a clean trade title can turn into a contributed mill after an ownership shift. Your floors only work if someone still opens the homepage.
