Backlink Checker — Backlinks, Referring Domains, Anchors & Authority

See who links to any website. Get every backlink with the referring page, anchor text, dofollow status, domain authority rank, and spam score — a powerful Ahrefs/Semrush alternative at a fraction of the price.

Audit your own link profile or reverse-engineer a competitor's. Filter to high-quality, dofollow, live links so you only see what matters. Pick an output mode: raw backlinks, a per-target summary (totals, referring-domain count, dofollow %, spam rollup), an anchor-text distribution, or a deduped referring-domains list. Clean, structured, API-ready output.

What you get per backlink

• 🌐 Referring domain & URL — exactly which page links to the target.
• 🔗 Anchor text — the clickable text of the link.
• ✅ Dofollow / nofollow — whether the link passes SEO value.
• 📊 Domain authority rank — strength of the linking domain (0–1000).
• 🛡️ Spam score — flag low-quality / toxic links.
• 🕒 First & last seen — link freshness and history.

Output modes

• Raw backlinks — one row per backlink (default).
• Summary — per target: total backlinks, referring-domain count, dofollow %, lost links, avg authority, and a spam-score distribution.
• Anchor-text distribution — top anchors with counts and share %.
• Referring domains — deduped linking domains ranked by authority, with link counts.
