Uncover Every Domain
Linking to Your Site
Instantly & Free
SEOScaleUp's free Referring Domains Checker reveals every unique domain pointing to any URL — giving you the competitive backlink intelligence you need to outrank rivals without paying $99/mo for it.
Your Free Referring Domains Intelligence Hub
A referring domains checker reveals every unique website that has placed at least one backlink pointing to your domain or a competitor's. Unlike raw backlink counts — which can be inflated by a single spammy domain linking 10,000 times — referring domain data shows the true breadth and diversity of your link profile, which is a core Google ranking signal.
SEOScaleUp's Referring Domains Checker aggregates data across our 500B+ indexed backlink database, surfacing domain authority, anchor text patterns, country distribution, TLD breakdown, and top linked pages — all from a single free lookup. Whether you're auditing your own site or reverse-engineering a competitor's backlink strategy, this tool delivers the actionable referring domain data you need instantly.
Everything You Need to Dominate Backlink Research
From raw referring domain counts to TLD-level breakdowns, every data point is engineered to give you a competitive edge — without the enterprise price tag.
Instant Referring Domain Lookup
Enter any domain or URL and get a complete count of unique referring domains in under three seconds. Our crawl infrastructure covers 500B+ indexed backlinks so your results are always comprehensive and current.
Domain Rating & Authority Score
Each referring domain is scored for authority so you can instantly distinguish high-value editorial links from low-quality spam. Prioritize link building efforts toward sites that actually move the needle on your rankings.
Full Backlinks List
Drill down from referring domain counts into the raw backlink list for any domain — see exact source URLs, anchor text, link type (follow/nofollow), and first/last seen dates to audit link freshness and relevance.
Top Linked Pages Analysis
See which specific pages on a domain attract the most referring domains. This reveals your competitors' highest-authority content so you can create superior alternatives and earn the same links — or better ones.
Country Distribution Map
Understand the geographic footprint of a site's backlink profile. See which countries most referring domains originate from — essential for local SEO audits, international campaigns, and identifying unnatural link patterns.
TLD Breakdown
View the breakdown of referring domains by top-level domain (.com, .org, .gov, .edu, country codes). A healthy mix of TLDs signals an organic link profile; a spike in low-value TLDs can flag manipulation to Google.
Top Anchor Text Analysis
Visualize the exact anchor text distribution across all referring domains. Over-optimized exact-match anchors are a major Google Penguin trigger — this view lets you audit and balance your anchor profile before it becomes a liability.
Competitor Backlink Gap
Compare your referring domain profile side-by-side with any competitor to instantly surface domains linking to them but not to you. These are warm outreach targets — sites already willing to link to content in your niche.
Export & Reporting Ready
Download your full referring domains report as a CSV with all data points intact. Share clean, professional reports with clients or import data directly into your link building CRM or outreach tool for immediate action.

Turn Backlink Data into Real Ranking Results
Referring domains are one of Google's strongest ranking signals. Knowing exactly who links to you — and who links to your competitors but not you — is the foundation of every effective link building strategy.
By identifying high-authority referring domains in your niche, you can target the same link sources your top-ranking competitors rely on — systematically closing the authority gap.
Spot toxic, spammy, or irrelevant referring domains before Google penalizes you. Our domain authority and TLD data makes it easy to build a disavow list with precision, not guesswork.
Reveal the exact domains linking to your top competitors in seconds. These are pre-qualified outreach targets — sites already proven to link to content in your space.
Over-optimized anchor text is one of the fastest ways to trigger a Penguin penalty. Our anchor breakdown lets you monitor and correct your profile proactively, before Google acts.
Track month-over-month growth in your referring domain count to measure the true impact of your outreach efforts — the metric that correlates most directly with organic ranking improvements.
