Most founders meet their own link data the same way: a tool shows a number, "your DR is 24" or "you have 340 backlinks", and nothing explains what sits behind it. For the definition of the underlying dataset, see our backlink profile glossary entry. This post is the practical half, the audit itself.
Set aside half an hour. You need no paid subscription, and the checklist below is repeatable every quarter.
The five things you are auditing
Five components determine whether a backlink profile is healthy or a liability:
1. Referring domains (not total backlinks)
A referring domain is a unique website linking to you, as opposed to a raw backlink count, which can include ten links from the same domain counted as ten. Referring domains matter more than total backlinks because Google's algorithms weigh the diversity of sites vouching for you more heavily than the raw volume of links. 40 links from 40 different domains signals far more than 400 links from one domain.
2. Anchor text distribution
Anchor text is the clickable words in a link. A healthy profile has varied anchor text, your brand name, your URL, generic phrases ("this tool," "click here"), and a modest share of keyword-rich phrases. A profile where 60%+ of links use the exact same commercial keyword as anchor text is a classic manipulation signal, the kind that shows up in link-scheme detection rather than looking like organic link growth.
3. Dofollow-to-nofollow ratio
Dofollow links pass link equity; nofollow links (marked with rel="nofollow" or the newer rel="sponsored"/rel="ugc") historically didn't, though Google now treats nofollow as a hint it may still choose to follow rather than a hard block. A natural profile has both. A profile that's 100% dofollow actually looks less organic than one with a healthy mix, since real-world link acquisition (social shares, news mentions, directory listings) naturally produces plenty of nofollow links.
4. Domain-level trust and relevance
Not every referring domain is equal. A link from a topically relevant, real, moderated site (a SaaS review platform, a niche blog with real traffic) carries more weight than a link from an unrelated, low-quality, or spam-adjacent domain. This is often summarized as a "spam score" by SEO tools, an estimate of how much of a domain's own link profile looks manipulative.
5. Link velocity
Velocity is how fast new referring domains appear over time. A sudden spike, 200 new referring domains in a week for a site that historically gained five a month, reads as unnatural and is the kind of pattern that draws scrutiny, whether from an algorithm or a manual review. Steady, gradual growth is the healthy pattern.
Key insight: referring domain count and anchor text diversity matter more to a backlink profile's health than raw backlink volume or a single high-DR link. A founder chasing "one big DR 90 link" is often optimizing the wrong variable compared to steadily adding 5-10 relevant referring domains a month.
Why diversity genuinely matters
The reason a backlink profile (the whole shape of your links) matters, rather than any single link, got fresh support from the 2024 leak of Google's internal API documentation. Summarizing the findings in an r/SEO thread, one commenter highlighted:
"The number and diversity of your backlinks still matter." (u/coolsheet, r/SEO)
A practitioner in the same discussion added a useful nuance on which links actually count: "no-followed links from pages that get a lot of organic traffic can pass page rank and increase ranking, but links that come from pages that get no organic traffic and are no-followed do nothing" (u/joyhawkins, r/SEO). Taken together, that is the case for reading your profile as a whole: it is not just the count, it is the spread across genuinely different, real, trafficked domains. The audit steps below are about seeing that shape clearly, so you can tell a diverse, natural profile from a thin or lopsided one.
The 30-minute audit, step by step
You don't need a paid tool subscription to get a real read on where you stand:
- Check your Domain Rating. Start with our free Domain Rating checker, powered by Ahrefs data, to see your current DR and a snapshot of referring domains.
- Look at referring domain count, not backlink count. If a tool shows 500 backlinks but only 12 referring domains, that's a concentration problem, not real authority.
- Scan anchor text for red flags. If you've done any link building, check whether your anchor text is dominated by one exact commercial phrase. That's worth diversifying going forward even if you can't fix historical links.
- Run a full technical scan. Our free SEO analyzer checks on-page and backlink-adjacent signals in one pass if you want a broader health check alongside the backlink-specific numbers.
- Spot-check your top referring domains manually. Click through to 5-10 of your highest-authority referring domains. Confirm the link is actually live, the page is indexed, and the site looks like a real, moderated destination rather than a link farm.
Red flags worth acting on
Watch for these when auditing your own site, or when evaluating whether a backlink-building tactic is safe:
- Anchor text over-optimization. More than roughly 30-40% of links using the exact same commercial keyword phrase.
- A cliff-edge velocity spike. Dozens or hundreds of new referring domains appearing in days, especially from low-quality or unrelated domains, a pattern Google's spam policies explicitly call out under link spam.
- Low referring-domain-to-backlink ratio. A handful of domains generating hundreds of links each, often from footer links, widget links, or comment spam.
- Off-topic link neighborhoods. Backlinks from sites with no topical relevance to your product at all, especially in bulk.
- Reciprocal link patterns. A high share of your referring domains also being sites you link back to. Also named directly in Google's link-spam guidance.
None of these are automatically fatal on their own, a real backlink profile always has some noise, but two or more together is worth investigating with a manual link audit.
Where directory submission fits
Directory submission, done selectively, is one of the more natural ways to build the first 20-40 referring domains for a new site, because it produces exactly the kind of diversity a healthy profile needs: a mix of dofollow and nofollow, a mix of DR levels, and anchor text that's mostly your brand name rather than a commercial keyword (most directories link your product name or a "visit website" button, not a chosen keyword phrase). That's structurally different from, and safer than, buying links or running a reciprocal-link scheme. See our directory submission sites list and high-DA directory submission sites for real, vetted starting points, and dofollow vs nofollow directories for how to think about the link-type mix specifically.
FAQ
What's the difference between a backlink profile and a backlink checklist?
A backlink profile is the actual current-state dataset, every link, its source, type, and quality. A checklist or audit is the process of reviewing that profile against known red flags. You need the profile data first before an audit means anything.
How many referring domains does a new site need?
There's no universal number, but 40-100 relevant, real referring domains is a reasonable early target for a new SaaS or startup site, achievable largely through vetted directory submissions in the first few months. Growth beyond that should slow to a steady trickle from content and outreach rather than another submission spike.
Can a backlink profile hurt my rankings?
Yes, if it's dominated by spam-adjacent domains, over-optimized anchor text, or an unnatural velocity spike. Google's algorithms and manual reviews both weigh these patterns, and in serious cases a toxic profile can trigger a manual action. Most small sites don't have anything that severe, but it's worth auditing rather than assuming.
How often should I check my backlink profile?
Quarterly is reasonable for most early-stage sites, more often (monthly) right after a link-building push like a directory submission run or a launch, so you can confirm links actually went live and stayed live. Use a free Domain Rating checker to track DR and referring domain count over time rather than guessing.
Build a clean link base from day one
Understanding your backlink profile is the first step. Building a good one, real referring domains, natural anchor text, a healthy dofollow/nofollow mix, is the actual work. BacklinkBot submits your product by hand to 100+ vetted directories (one-time, from $99), the kind of foundation layer that builds a healthy profile rather than a risky one, and sends a proof report with every live link.
