Skill · SEO backlink audit
SEO backlink audit.
Profile health, anchor mix, toxic links, reclamation, and the competitive gap.
Audit a backlink profile across five dimensions and produce a health verdict, a toxic-link list when one is needed, a reclamation list, and a gap analysis against competitors. The work suits a periodic health check, a manual-action recovery, a disavow scope, or due diligence on link equity.
It runs on Ahrefs MCP data. The discipline is evaluating links rather than counting them, and reaching for a disavow only when there is real evidence of harm.
Audience: SEO teams checking backlink health, recovering from a manual action, scoping a disavow, or building a baseline before a link campaign.
The framework
Five dimensions of a backlink profile.
A profile is healthy when all five dimensions are. An issue in any one can cap rankings or invite a penalty.
- 01Referring domain quality: a long tail of relevant, established linking domains. Volume matters less than quality and relevance; concentration in any single source is a risk.
- 02Link velocity: steady positive growth in referring domains. Sudden spikes suggest paid campaigns or negative SEO; sudden drops correlate with redirect mistakes or content removal.
- 03Anchor text distribution: branded and naked-URL anchors dominate, with exact-match keyword anchors a small minority. Heavy exact-match concentration triggers spam filters.
- 04Link types: editorial, in-content, dofollow links from relevant sites dominate, distinguished from directory, comment, footer, and sponsored or UGC-tagged links.
- 05Competitive gap: the domains linking to peers but not the target, with a healthy signal being a gap that shrinks over time rather than widens.
Runs on this platform
The audit's data backend.
The audit runs on the Ahrefs MCP: the referring domains, anchor text, link types, velocity, and competitor overlap all pull from the Ahrefs integration. Ahrefs sees most links but not all, so the audit triangulates with Search Console for completeness.
How to read a profile
Evaluate links; do not count them.
A profile is healthy when all five dimensions are, and a problem in any one can cap rankings or invite a penalty. The most common mistake is counting links instead of evaluating them: a profile with 10,000 referring domains can be weaker than one with 200 high-quality editorial links, and Domain Rating is a relative metric, not a quality signal, so a DR-30 niche site can be worth more than a DR-80 generalist.
Most profiles do not need a disavow. Disavowing legitimate links damages rankings, so reserve it for a confirmed manual action or a clear algorithmic signal rather than treating it as routine hygiene. Investigate before reacting to a high exact-match anchor percentage, which is normal for niche sites where the brand name and the keyword overlap.
Recovering a lost link is faster and cheaper than building a new one, so the reclamation list earns its place beside the toxic and gap lists. Profile health drifts, so audit on a cadence (quarterly for active properties), and benchmark against competitors, because a backlink count that is low for a tier-1 competitor can be excellent for a niche site.

Bridges to other skills
What the audit hands off to.
The audit diagnoses the profile. These act on its lists, set the competitive frame, and roll it into a wider audit.
Build and reclaim
seo-offpageTakes the reclamation and gap lists and acts on them: outreach, linkable assets, and digital PR. The audit names the targets; off-page work earns the links.
The wider frame
seo-competitorThe competitive-gap dimension is one angle of a full competitor analysis. Start there for the field, here for the backlink profile in depth.
The full audit
seo-audit-orchestrationThe orchestrator runs this audit as one dimension of a coordinated suite. Reach for it when the brief is a whole-site baseline, not a link-only check.
Non-link technical
seo-site-health-auditTechnical issues unrelated to links sit there. This audit owns the link profile; that one triages crawl and indexing findings.
The keyword side
seo-keyword-gap-auditKeyword opportunity analysis is a separate audit on the same Ahrefs backend. Links build authority; the keyword gap finds what to point it at.

Frequently asked questions.
- What are the five dimensions of a backlink profile?
- Referring domain quality (the quality and relevance of the linking domains rather than the count), link velocity (how fast links are gained or lost), anchor text distribution (the mix of anchor types and whether it looks natural), link types (editorial versus directory, dofollow versus nofollow, in-content versus footer), and the competitive gap (what links peers have that the target does not). A profile is healthy when all five are healthy, and an issue in any one can cap rankings or invite a penalty.
- When should I disavow links?
- Rarely. Most profiles do not need a disavow, and disavowing legitimate links actively damages rankings. Reach for it only after a Google manual action or a clear algorithmic signal, not as preemptive hygiene. Being disavow-happy is a top failure mode, as is panicking over a high exact-match anchor percentage, which is fine in absolute terms for niche sites where the brand and the keyword genuinely overlap. Investigate the cause before building a disavow file.
- What does a healthy anchor text profile look like?
- Branded and naked-URL anchors dominate, generic and partial-match anchors fill the middle, and exact-match keyword anchors are a small minority. Heavy exact-match concentration looks engineered and triggers spam filters. The exception worth checking is a niche site where the brand name and the target keyword are nearly the same phrase, which inflates the exact-match share for an innocent reason, so investigate the distribution before treating it as a problem.
- Is a bigger backlink count better?
- No. Count quality, not links: a profile with 10,000 referring domains can be weaker than one with 200 high-quality editorial links from relevant sites. Domain Rating is a relative metric rather than a quality signal, so a DR-30 niche site that is genuinely relevant can be more valuable than a DR-80 generalist. And profile health is relative to the field, so a backlink count that looks low against a tier-1 competitor can be a strong count for a niche property.
- Should I trust Ahrefs as the complete picture?
- Ahrefs sees most links but not all, so triangulate with Search Console for completeness, especially when scoping a disavow or recovering from a manual action where missing a link matters. The audit pulls referring domains, anchor text, link types, velocity, and competitor overlap from the Ahrefs MCP, then cross-checks the gaps. And do not ignore lost links: recovering one is faster and cheaper than building a new one, so the reclamation list is part of every audit.
