No http:// needed. 2. **Run the live audit** — The tool crawls the page and measures its link graph: external links, referring domains, dofollow/nofollow rel attributes, anchor text, and TLD spread. 3. **Read the dashboard** — Review the estimated authority, trust score, link-equity flow, anchor-type mix, top referring domains, and any toxic domains flagged by spam-pattern detection. 4. **Export and act** — Copy the report, download the linked-domains CSV, or generate a Google-format disavow.txt for the toxic domains to submit in Search Console after manual review. ## Common use cases - A site owner checks whether spam links or a skewed anchor profile are hurting rankings. - An SEO reviews the dofollow/nofollow ratio and anchor-text mix for over-optimization. - A marketer benchmarks a competitor's referring domains and TLD spread. - An agency generates a disavow file for a client's toxic backlink cleanup. - A new site tracks its outbound link hygiene and authority estimate over time. ## About ### Understand your backlink profile The backlink auditor helps you review the links tied to a site so you can gauge authority, spot spammy or toxic domains, and find referring pages worth building a relationship with. Every raw number — link counts, referring domains, dofollow/nofollow split, anchor mix — is measured live from the page, not fabricated. A clean, relevant link profile is still one of the strongest off-page ranking factors, and seeing it laid out in one dashboard turns guesswork into a plan. ### Protect rankings from bad links Low-quality or manipulative backlinks can drag a domain down, especially after algorithm updates. The auditor flags spam-pattern domains and suspicious TLDs, then generates a Google-format disavow.txt you can review and submit in Search Console. Use it to benchmark your profile against competitors and turn a vague 'we need more links' goal into a concrete, quality-first outreach and cleanup plan. ### Read anchor text like an SEO Anchor text is a top over-optimization signal. The tool classifies every anchor as branded, keyword, generic, naked URL, or empty/image, and shows the percentage mix. A natural profile leans on branded and generic anchors with keyword anchors used sparingly. If one exact-match keyword dominates your anchors, that's exactly the pattern Google's spam filters look for — this report makes it obvious at a glance. ### Estimated authority, explained honestly A free single-request tool can't query a paid backlink index, so the Estimated Authority score is a deterministic composite of the real signals we can measure — link volume, referring-domain diversity, HTTPS, follow discipline, and toxicity. The same site always returns the same score. Treat it as a directional health estimate, not an index-based DA/DR from Ahrefs or Moz. The methodology is shown right on the results so you always know what the number means. ## FAQ ### How do I check my website's backlinks for free? Enter your domain URL and the tool analyzes your backlink profile, showing referring domains, anchor text distribution, and domain authority scores. ### Are backlinks still important for SEO in 2025? Yes. Backlinks from authoritative, relevant sites remain one of Google's top 3 ranking factors. Quality matters far more than quantity — one backlink from a DA 80+ site is worth more than 100 links from DA 10 sites. ### What is domain authority (DA)? Domain Authority (DA) is a score from 0-100 developed by Moz that predicts how well a website will rank in search engines. A DA of 40+ is generally considered good. Higher DA = more ranking power. ### How do I remove toxic or spam backlinks? First, try contacting webmasters of toxic sites to request link removal. If unsuccessful, create a disavow file listing those URLs and submit it to Google Search Console to tell Google to ignore those links. ### What anchor text distribution is healthy? A natural anchor text profile is: 40-60% branded anchors (your site name), 20-30% generic (click here, read more), 10-20% keyword-rich anchors, 5-10% URL anchors. Over-optimized keyword anchors can trigger Google penalties. ### How many backlinks do I need to rank on page one? It depends on the keyword's competition. For low-difficulty keywords (KD 0-30), even 5-20 quality backlinks can achieve page-one rankings. For competitive terms (KD 60+), you may need hundreds. Focus on earning backlinks from topically relevant, high-DA sites — one strong link beats 100 weak ones. ### What's the difference between dofollow and nofollow links? Dofollow links pass ranking signals ('link equity') to the target site; nofollow links (rel="nofollow", plus rel="ugc" and rel="sponsored") ask search engines not to pass that authority. A natural profile mixes both — typically 10–40% nofollow. This auditor reads each link's rel attribute and shows the exact split so you can spot an unnatural, all-dofollow or all-nofollow pattern. ### How do I create a Google disavow file? Run the audit, review the toxic domains it flags (spam keyword patterns and suspicious TLDs), then click 'Download disavow.txt'. The file is already in Google's format (one domain: entry per line with comments). Verify every entry manually, then upload it in Google Search Console's disavow tool. Disavow only genuinely harmful links — over-disavowing can remove links that were actually helping you. ### Is the domain authority score in this tool the same as Moz DA? No. This is an Estimated Authority score computed deterministically from the signals a live page crawl can measure (link volume, referring-domain diversity, HTTPS, follow discipline, and toxicity). It's a directional health estimate, not the index-based DA from Moz or DR from Ahrefs, which require crawling the entire web. The methodology is shown right on the results page so you always know what the number represents. ### Are backlinks still important for SEO? Yes. Quality backlinks remain one of the strongest ranking signals, though relevance and authority matter far more than raw quantity. ### How do I handle toxic backlinks? First try outreach to have them removed; for links you can't remove, Google's disavow tool tells search engines to ignore them. --- ToolNova — free, privacy-first browser tools.
