A dofollow nofollow backlink checker is any tool that lists the links pointing at a domain and labels each one with the rel attribute found in the source HTML. It answers a simple question — which of my backlinks carry a link attribute that tells Google to discount them — and it is one of the first things worth checking when you inherit a site or audit a link campaign.
The catch is that most explanations of dofollow and nofollow are stuck in 2018. The rules changed. Here is the accurate version.
What the rel attribute actually is
There is no such thing as a “dofollow” attribute in HTML. A normal link is simply a link:
<a href="https://example.com">— no rel attribute. This is what people call dofollow. It is the default.rel="nofollow"— introduced in 2005 to combat comment spam.rel="sponsored"— introduced by Google in September 2019 for paid and affiliate links.rel="ugc"— also introduced in 2019, for user-generated content such as comments and forum posts.
“Dofollow” is industry slang for the absence of any of these. Checkers use it because it is convenient, not because it exists in the specification.
The 2019 change everyone still gets wrong
In March 2020, Google began treating nofollow — along with sponsored and ugc — as a hint rather than a strict directive. For crawling and indexing purposes the change took effect earlier, in September 2019.
Practically, that means Google reserves the right to crawl a nofollowed link and to consider it as a ranking signal if it judges that useful. It is no longer a guaranteed wall. The old shorthand “nofollow links pass no value” is not what Google says and has not been since 2019.
It also does not mean nofollow links are as valuable as followed ones. The honest position is in the middle: a followed editorial link from a relevant site is the strongest form. A nofollowed link may be crawled, may be counted, and definitely still delivers referral traffic, brand visibility, and the kind of mention that other people later link to without an attribute. Treat nofollow as “probably discounted, occasionally not, still worth having.”
The attributes are also combinable. rel="sponsored nofollow" is valid and common, and a good checker will show every value present rather than collapsing them into a single yes/no column.
What a backlink checker can and cannot see
A link checker builds its data from a crawler. It fetches pages, parses anchor tags, and records the href, the anchor text, the rel value, and the page it appeared on. So the report reflects what a crawler saw on its last visit to that page.
Three limits follow. Coverage is partial — no crawler has the whole web, and small or new sites are underrepresented. Freshness varies — a link removed last week may still be listed, and a link added yesterday may not appear yet. And links injected by JavaScript after page load are sometimes missed entirely, depending on whether the crawler renders.
Every third-party backlink metric is an estimate. Domain-level authority scores, referring domain counts, and toxicity flags are modeled, and different vendors will give you different numbers for the same site. Use them to compare and prioritize, not as absolute truth.
How to run the audit
- Pull the full backlink report for your domain. Note total backlinks and, more importantly, total referring domains — one site linking 500 times is one relationship, not 500.
- Segment by rel attribute. Look at the split between followed, nofollow, sponsored, and ugc.
- Check anchor text distribution. A healthy profile is mostly branded and naked-URL anchors with a minority of exact-match commercial anchors.
- Review referring domain quality. Relevance beats raw authority. A niche site with modest metrics that genuinely covers your subject is worth more than a high-authority general directory.
- Flag the obvious junk — spun content, link farms, sitewide footer links from unrelated sites, sudden bursts from a single network.
- Verify a sample by hand. Open five or six source pages and confirm the link and the attribute are actually there. Data errors are common enough to matter.
What a healthy followed/nofollow ratio looks like
There is no target ratio, and anyone quoting one is guessing. Natural profiles vary enormously by industry: a SaaS product mentioned in forums and Reddit threads will run heavy on ugc and nofollow, while a publisher cited by other publishers will skew followed.
The useful comparison is against competitors, not an abstract ideal. Pull the profiles of three or four sites ranking for your main terms and look at their splits. If they average 70% followed and you sit at 15%, that gap is a real signal about where your links come from. If your split is close to theirs, stop worrying about the ratio and start worrying about relevance.
What genuinely looks unnatural is not a ratio — it is a pattern. Hundreds of exact-match anchors, a spike of 400 domains in a week, links from sites in unrelated languages and industries. Those are the shapes that draw scrutiny.
Where SEO Rocket fits, and where it does not
SEO Rocket includes a site explorer for any domain with backlinks, referring domains, anchor text, domain rating, and spam or toxic flags, plus a backlink gap report that shows which sites link to your competitors but not to you, with a named outreach list and niche-based cost bands presented as directional estimates only. That is enough to audit a profile, understand attribute splits at a domain level, and build a target list.
It is not a disavow-file manager, and it is not a dedicated link-monitoring service that emails you the moment a specific placement drops. If you are running a large paid-placement program and need per-link uptime monitoring, use a purpose-built link monitor alongside whatever suite you already pay for. That is the honest answer.
Checking your own outbound links
The attribute question runs both ways. Links you publish also carry rel values, and getting them wrong creates real risk. Any link you were paid for — affiliate links, sponsored posts, paid reviews, gifted product mentions — should carry rel="sponsored" or at minimum rel="nofollow". Undisclosed paid links are one of the clearer link-scheme violations Google names.
User-generated areas need the same treatment. Comments, forum posts, and profile fields should apply rel="ugc", ideally combined with nofollow, and most mature CMS platforms do this automatically. Verify it rather than assume it; plugin changes and theme updates break these defaults more often than people expect.
Everything else — genuine editorial citations, references, sources you chose freely — should stay followed. Blanket-nofollowing every outbound link on a site is a common overcorrection with no upside. Linking to good sources is normal publishing behavior, and it costs you nothing meaningful.
The judgment that matters more than the checker
Link attributes are a small part of link value. Before chasing a followed link, ask whether the page will ever be read by someone in your market, whether the site’s topic genuinely overlaps yours, and whether the link sits inside real editorial content rather than a footer or a paid list.
Links are necessary but not sufficient. Thin content with strong links still loses, and strong content with no links stalls. Run the checker quarterly, fix what is clearly toxic, understand your attribute split relative to competitors, and then spend the remaining time earning placements that would send you traffic even if search engines did not exist. That test filters out almost every bad link opportunity before you waste a month on it.
