Backlinks are still the strongest single ranking signal Google uses, two decades after PageRank. The questions every SEO ends up asking — How many sites link to me? How authoritative are they? What anchor text are they using? Am I losing links faster than I'm gaining them? — are all questions about your backlink profile, and all of them require a fresh dataset to answer honestly. That's what this tool gives you, in a public report you can share.
The data layer underneath is DataForSEO's live backlink index — the same source most paid SEO platforms run on. We pull a fresh snapshot at scan time and surface the signals that actually move rankings: total backlink volume, the count of unique referring domains (more important than raw link count, because a hundred links from one site count as roughly one signal), the dofollow-to-nofollow split (only dofollow links pass authority), the top 20 anchor texts (Google reads these as topical signals, and an unbalanced anchor profile reads as spam), and lost backlinks since the last scan (often the leading indicator of a decay problem).
Each linking domain comes with its own Domain Rank (0–100) so you can immediately tell whether a backlink is doing anything for you. A link from a DR-80 site is worth roughly the same as thousands of links from DR-5 sites; the score is logarithmic, not linear. The Top backlinks table is sorted by referring-domain DR descending so the highest-leverage links sit at the top of the page.
We pull live backlink data from DataForSEO and surface the signals that move search rankings.
| Signal | Surfaced | What we show |
|---|---|---|
| Top backlinks | Top 50 | Highest-authority backlinks pointing at the domain. |
| Referring domains | All | Unique domains linking back, with their domain rank. |
| Anchor text | Top 20 | Most-used anchor phrases across all backlinks. |
| Dofollow / nofollow | Split | Ratio of link-juice-passing vs nofollow links. |
| Domain Rank (DR) | 0–100 | Aggregated authority score for each linking domain. |
Three patterns where a public, shareable backlink report earns its keep.
Run a no-signup backlink audit on a prospect's domain before the call. The DR-by-domain table makes the "you have a link diversity problem" conversation concrete in 60 seconds.
Pull a competitor backlink snapshot, drop the URL into a slide, and use it to argue for a digital-PR budget. The shareable URL means stakeholders can verify the data themselves.
Track outreach campaign progress without a Semrush seat. Compare run-to-run history to confirm new partnerships and guest posts are actually showing up in your backlink index.
Each scan produces these panels — here's what each one tells you.
KPI strip
Total backlinks, referring domains, dofollow ratio, average DR. The headline numbers stakeholders ask about first.
Top backlinks table
Sorted by referring-domain DR descending. The highest-leverage 50 links live here — these are the ones worth nurturing relationships with.
Anchor text distribution
The top 20 anchor phrases. A healthy profile is mostly branded + naked-URL, with topical anchors thinned out. Heavy match-anchor usage is what triggers spam-penalty review.
Lost backlinks
Backlinks that existed in a previous scan and no longer exist. The first place to look when rankings drop without an apparent cause.
We query DataForSEO's live backlink index at scan time. DataForSEO maintains a multi-billion link index updated continuously from a fleet of crawlers — it's the same data source most paid SEO platforms (Semrush, Ahrefs, Majestic) draw from at the wholesale layer.
"Live" here means the snapshot is current as of the scan timestamp. Backlink indexes never represent the absolute total of every link on the web — no commercial index does — but the relative shape of the profile (DR distribution, anchor distribution, dofollow split) is stable enough to make decisions on.
We surface up to 50 backlinks in the headline table, sorted by referring-domain DR. Full referring-domain count is unbounded — every unique linking domain is reported, even those beyond the top-50 link cutoff. Anchor text is aggregated from all known backlinks (not just the top 50) and the top 20 by frequency are surfaced.
Lost backlinks compare the current scan against the most recent prior scan of the same domain. A "lost" link means we saw it last time and don't see it now — it could be a true loss (the linking page was deleted, the link was removed) or a temporary index gap. Treat individual losses as signal, mass losses as a problem worth investigating.
Three reference profiles for context.
Weak profile
Under 20 referring domains
Low DR linkers, mostly nofollow, anchor distribution heavy on exact-match keywords. Either very new, or built primarily through low-quality directory listings. Won't move competitive rankings.
Average profile
50–200 referring domains
Mix of DR-20 to DR-50 linkers, a couple of higher-DR mentions, mostly natural anchors. Where most established SaaS / SMB sites sit. Enough to compete on long-tail; need more for head terms.
Strong profile
500+ referring domains
Multiple DR-70+ inbound links, healthy dofollow ratio, balanced anchor distribution, low lost-link rate. Site can compete on most non-elite head terms; growth from here is incremental.
No fixed number. It depends on keyword competitiveness and the quality of the linking domains. A long-tail keyword can rank with under ten quality backlinks; "best CRM software" might need hundreds. Run a backlink check on the top three results to set a realistic floor.
Yes — just not how most people think. Nofollow links don't directly pass ranking signal, but they drive referral traffic, build brand awareness, and contribute to a natural-looking profile. A site whose backlinks are 100% followed looks manipulated. Some nofollow links (Wikipedia, Reddit) are also cited by AI engines.
They can. Links from spammy sites, link farms, or PBNs can trigger algorithmic penalties — Google's SpamBrain and Penguin are trained to detect manipulation. If you suddenly see hundreds of low-quality backlinks pointing in, run them through this checker, identify the worst offenders, and submit them to Google's Disavow Tool. Most natural profiles never need this.
Monthly for most sites. Weekly if you're running an active outreach or PR campaign. Bookmark your report at /bl/<domain>/ — re-running the scan automatically diffs against the prior result, surfacing new links earned and old ones lost. That diff is where the actionable insight lives.
Three paths in order of effort: (1) email the linking webmaster and ask politely — slow but free; (2) if no reply, add the URL to a Google Disavow file (disavow.txt) and submit via Search Console; (3) for entire spammy domains, use the domain: prefix in the disavow file to neutralize every link from that source.
Yes, indirectly. ChatGPT, Perplexity, and Google's AI Overviews use citation signals that overlap heavily with traditional link authority — they cite domains that other authoritative pages link to. A page nobody links to is unlikely to be cited by AI engines. Pair backlink work with mentions in editorial roundups.
Google has to crawl the linking page, recognize the link, and reassess your authority. That cycle typically runs one to four weeks for established sites, up to eight for newer domains. AI engines work on different cycles — citation surfaces can update in days for fast-moving stories or take months for slow corpus refreshes.
No. Paid links violate Google's spam policies, and detection has caught up — SpamBrain looks at unnatural link velocity, anchor patterns, and seller-network footprint. Penalties range from devalued links (best case) to full site demotion (worst). Editorial coverage you earn is slower but compounds. The math favors earned links.
Ahrefs and Semrush run their own backlink crawlers and have their own indexes; we use DataForSEO. The relative profile shape (DR distribution, anchor mix) is comparable; absolute counts will differ between any two indexes by 10–30%. For a free, no-signup look at a domain you don't own, this is meaningfully cheaper than a paid seat.
Google Search Console reports backlinks Google itself has discovered and confirmed. Third-party indexes (DataForSEO, Ahrefs, Semrush) discover links Google may not have indexed yet, plus links Google saw but doesn't surface in GSC. The two will rarely match — both are "right" for different definitions of "backlink".
Yes — the tool works on any public domain. Run a competitor's domain through the checker, then compare anchor text and top referring domains against your own. The biggest backlink-strategy lifts come from filling gaps your competitors have already proven are reachable.
A backlink the index saw on the previous scan and doesn't see on this one. Real-world causes: the linking page was deleted, the page was edited and the link removed, the page now redirects elsewhere, or the page is now blocked from crawlers. A few losses every scan is normal; a sudden cluster is worth investigating.
As of 2019, Google treats rel="nofollow", rel="ugc", and rel="sponsored" as hints rather than directives. Some authority does pass — but conservatively. Treat dofollow as the primary ranking-signal column and nofollow as referral-traffic + brand-mention value.
DataForSEO's backlink index is updated continuously, with the bulk of recently-discovered links appearing within 1–4 weeks of being crawled. Brand-new outbound links from low-traffic sites can take longer; links from high-traffic publishers usually appear within days.
rel="nofollow" tells search engines not to pass authority through the link. Dofollow (no rel attribute) passes authority. Most links default to dofollow.
