Domain authority and backlinks: no metric fetishism
The score is a comparative indicator, not a target to maximize.
The most common mistake is metric fetishism: letting the domain score guide the choice of links, accepting links from sites with a “high DA” but no relevance and no real traffic. It is an approach that inflates a number rather than real authority, and sometimes makes things worse, because many of those sites exist only to sell links. I use these metrics to guide the analysis of the link profile, which is part of brand authority and is carried out with link building.
The scopeWhat domain authority measures, and what it doesn’t
The domain authority is a third-party metric (created by Moz, with equivalents such as Ahrefs’ Domain Rating) that estimates, on a scale from 1 to 100, the likelihood that a domain ranks well, based mainly on its profile of backlinks, an evolution of the concept of PageRank. It is not a Google metric and not a ranking factor: it is a comparative indicator useful for assessing a site’s relative strength against competitors, as long as it is not treated as a goal in itself.
Domain authority and similar metrics estimate the strength of the link profile: how many domains point to the site, how authoritative they are in turn, how they are distributed. They are calculated by third-party companies with their own models and crawlers, so the value can differ from one tool to another for the same site. They are comparative: they make sense when comparing sites in the same field, not as an absolute grade.
TWO SITES WITH THE SAME SCORE CAN BE VERY DIFFERENT
THE METRIC IS A STARTING POINT, NOT THE CONCLUSION
What they don’t measure: the topical relevance of links, the real traffic of the pages that link, the quality of the site’s content, theE-E-A-T, entity consistency, unlinked mentions. Two sites with the same domain authority can have very different real authority. That is why the metric is a starting point for the analysis, not the conclusion.
What makes a backlink valuable
The quality of a backlink depends on factors that domain scores capture only in part. A link that meets these criteria strengthens authority even if it comes from a domain with a modest score.
Topical relevance
A link from a site covering nearby topics is worth far more than one from a generic site.
Real traffic
The page hosting the link receives real visits and is not a container built to sell links.
Position and context
Within the body of a relevant piece of content, not at the bottom of the page or in lists of unrelated links.
Naturalness of the anchor text
Prevalence of brand and URL, measured use of exact matches.
Contribution to diversity
A new domain, not yet another link from the same site.
How I analyze the link profile
A backlink analysis service doesn’t just read the Domain Authority: I examine the backlink profile, referring domains, relevance, anchor text and risks to understand which actions can really strengthen SEO authority.
Mapping
Referring domains, authority and relevance, distribution of anchors, trend over time, share of potentially harmful links.
Comparison with competitors
Those who hold the SERPs of interest: where the gap is real and where it is only apparent (high metric but irrelevant links).
Identifying weak points
Important pages with little incoming authority, uncovered topics, excesses of exact anchors.
Risk check
Presence of links from site networks, spam contexts, unnatural patterns.
Plan
Target pages, topics, type of links to build, any cleanup.
Monitoring
New relevant links, lost links, evolution of real authority and of the target pages’ ranking.
The right question isn’t “how do I raise the DA”, but “why doesn’t this page rank».— Andrea Viggiano, link profile analysis
How domain metrics are used
| Correct use | Incorrect use |
|---|---|
| Comparing relative strength against direct competitors | Treating the score as a goal to maximize |
| Initial filter, then assessment of relevance and traffic | Choosing links based only on the score |
| Observing the trend over time | Reading the absolute value as a grade |
| Cross-checking several tools | Relying on a single metric as the truth |
Low domain authority: when it’s a problem and when it isn’t
A low domain score is not a problem in itself: many sites rank well on niche queries with modest but relevant link profiles. It becomes a problem when it explains why pages well optimized in content and technique don’t get past a certain threshold on competitive queries: if the sites holding the top positions have much stronger and more thematic profiles, that is the gap to close, gradually and with quality links.
Toxic backlinks and disavow
Some profiles contain clearly artificial links — from site networks, from spam contexts, with repeated exact anchors. Google states it can automatically ignore most of these links, so the disavow tool should be used with caution: it makes sense when there is a manual action tied to links, or when the profile shows an extensive, documentable manipulative pattern that the site inherited or suffered. Routinely applying disavow, on lists generated automatically by a tool, can remove harmless links and do more harm than good. Case-by-case analysis is the rule.
Domain metrics and AI answer engines
Domain scores play no direct role in how generative engines choose the sources to cite: what counts is real authority on the topic, entity consistency, clarity of content, consensus among sources. A relevant link profile contributes to this authority, but chasing the domain metric — perhaps with off-topic links from high-score sites — does not increase the likelihood of being cited, and doesn’t move Generative Engine Optimization. What moves it is the underlying work on content, entities and relevant mentions.
The other link profile metrics
Besides the overall domain score, tools offer more specific indicators that often say more. The number of referring domains is more meaningful than the total number of links, because a hundred links from a single site are worth less than ten links from ten different sites. The distribution of anchor texts reveals whether the profile is natural (prevalence of brand, bare URLs, generic phrases) or constructed (too many exact matches with the target keywords). The ratio between follow and nofollow links and its evolution. The growth over time: a gradual, continuous curve is healthy, sudden spikes of dozens of links are a sign of manipulation. And the topical relevance of the referring domains, which no summary score captures well and which must be assessed by looking at the sites one by one.
Incoming authority to the right pages
A frequent mistake is to concentrate links on the home page, leaving the pages that need to rank — service pages, pillars — without incoming authority. Work on the link profile therefore starts by identifying the target pages and checking how much internal and external authority they receive. Often the quickest lever is not acquiring new external links, but redistributing the authority already present with better internal linking: linking the site’s strong pages to those to push, with descriptive anchors. New external links are then directed, when possible, to those same pages or to content that supports them.
Effective link building starts from the pages that must generate demand and authority, not from an undifferentiated accumulation of links. I assess editorial relevance, quality of referring domains, anchor text, risk and the content’s ability to earn citations over time. In my work the link profile is tied to content, service pages and commercial goals: every opportunity is checked before entering the plan.
The link profile over time
A link profile is not static: links are lost (sites that close, pages removed, newsrooms that redo an article), new ones are acquired, the balance with competitors changes. Periodic monitoring serves to catch the loss of important links — to recover with a restoration request — the appearance of suspicious links that were not requested, and theevolution of the gap with the sites holding the top positions on the target queries. The profile should be managed as a living asset, not photographed once and filed away.
How work on the link profile is measured
The useful indicators are the growth of relevant referring domains over time, the distribution of anchors that stays natural, the diversity of the profile, and above all the effect on the target pages: whether, after building incoming authority, those pages gain positions on competitive queries where they were previously stuck. The domain score is read as a comparative trend against competitors, not as a figure to show off. A profile that grows in quality and relevance produces results even if the number on the tool moves slowly.
Frequently asked questions about domain authority and backlinks
Is domain authority used by Google?+
No: it is a third-party metric. Google used the concept of PageRank in the past and assesses authority with its own signals, but there is no public “Google domain authority”.
How do I increase domain authority?+
The right question is how to strengthen real authority: by earning relevant links and mentions from quality sources, with natural growth over time. The tool’s score tends to follow, but it is not the goal.
Is a link from a DA 20 site useless?+
No: if it is relevant, contextual and from a page with real traffic, it can be worth more than a link from a DA 60 site with no relation to your topic. Relevance beats the score.
Should I disavow the links the tool flags as toxic?+
Not automatically. Google ignores most low-quality links. Disavow is assessed case by case, usually in the presence of a manual action or a documented manipulative pattern.
Why do tools give me different values?+
Each tool uses its own crawler and its own model, with a partial link index and different criteria. Values should be read within the same tool and in comparison with competitors, not across different tools.
Is it a standalone service or part of brand authority?+
Link profile analysis is part of brand authority and is carried out together with link building. The domain score is one of the analysis’s tools, not its purpose.
A competitor has a much higher DA: is it unreachable?+
Not necessarily. If their score comes from many irrelevant links, the real gap on the queries of interest may be smaller than it looks. You analyze their profile to understand how much of their authority is topical and recoverable, and on which queries it is best to compete first.
Do social media links count for the profile?+
Links from the main social networks are generally nofollow and don’t transfer authority like an editorial link. They do contribute to spreading content, though, and can indirectly generate mentions and links from other sites.
How often should the link profile be analyzed?+
An in-depth review once or twice a year, with lighter monthly monitoring to catch the loss of important links or the appearance of suspicious ones. After link building or digital PR work, a targeted check on the effect obtained is worthwhile.
How much does a backlink profile analysis cost?+
It depends on the size of the domain, the number of competitors and the level of detail required. I first define the target pages and the scope of the audit, then propose a proportionate plan of analysis and link building.
What are backlinks for?+
They can transfer authority signals and help Google discover and assess pages, but their value depends on relevance, quality and naturalness. Increasing the number is not enough: I analyze the profile and build coherent opportunities for the sector.
What are internal links for?+
Internal links distribute context and authority among the site’s pages, help users and crawlers reach the important content and support the topical hierarchy. That is why they are part of the strategy alongside backlinks, not an alternative.
