About the tool

What is the SBMM Backlink Audit?

The SBMM Backlink Audit is a free online backlink checker that live-verifies up to 100 inbound links per run. Paste a list of URLs claiming to link to your site (from your Ahrefs, Semrush, or Majestic export, or from a manual outreach tracker) and the audit confirms each link is still live, classifies its rel attribute, extracts its anchor text, and flags dead or changed links so you know exactly what you are working with.

Third-party backlink databases lag the live web by days or weeks. A backlink that shows up in Ahrefs may already have been removed, switched to nofollow, or quietly turned into a UGC link after a moderator review. Acting on stale data wastes outreach hours, distorts disavow files, and can lead to penalty appeals based on links that no longer exist. Clean your backlink export with our URL Editor first to deduplicate, lowercase, and force HTTPS, then run this audit.

This audit fixes the freshness problem by fetching each referring URL in real time, parsing the rendered HTML, confirming the link is present, and reading the rel attribute as it stands today. It is the fastest sanity check before you submit a disavow file, before you celebrate a placement, or before you trust a competitor backlink report.

Step by step

How to use this tool in 3 steps

  1. Step 01

    Paste your backlink URL list

    Drop up to 100 URLs (one per line) into the form. These are the referring pages you want to verify, not the target pages on your own site. You can paste straight from an Ahrefs / Semrush / Majestic export.

  2. Step 02

    Live HTTP fetch of each URL

    The audit fetches every referring page live, parses the HTML, looks for an outbound link matching your target domain, classifies the rel attribute (dofollow / nofollow / UGC / Sponsored), extracts the anchor text, and records the HTTP status.

  3. Step 03

    Review the report and act

    See a per-link table sorted by status: live + dofollow, live + nofollow, dead, redirected, or anchor changed. Export the cleaned list as CSV and feed it into your disavow file, outreach tracker, or client report.

Why this tool

Why use this tool

  • Live HTTP verification

    Every URL is fetched in real time, not pulled from a cache. The dofollow / nofollow / UGC / Sponsored classification reflects the rel attribute as it stands at audit time, not as it stood when the database was crawled.

  • 100 backlinks per run

    Audit up to 100 referring URLs in one batch on the free tier. Enough for a full sanity pass on a fresh Ahrefs export, an outreach campaign summary, or a competitor backlink slice.

  • rel attribute split

    Reports each link as dofollow, nofollow, UGC, or Sponsored. Dofollow links pass equity; nofollow / UGC / Sponsored links do not. Knowing the split is critical for risk weighting and disavow decisions.

  • Anchor text extraction

    Pulls the exact anchor text from the live HTML so you can spot over-optimised anchors (a known Penguin trigger) and verify a placement matches the anchor you brokered in outreach.

  • HTTP status per link

    Flags 200 (live), 301 / 302 (redirected), 404 (dead), 410 (gone), 503 (server issue), and rare codes. Dead links are surfaced first so you stop wasting outreach time on URLs that no longer exist.

  • Free, no sign-up, one run a day

    One full 100-link audit per day on the free tier covers a normal solo SEO workflow. SBMM Pro lifts the cap, adds DA estimation, and ships a multi-week link-rot watchlist for the links you care about most.

FAQ

Frequently asked questions

Why audit backlinks at all?

Backlinks are the strongest off-page ranking factor and remain a confirmed Google signal in 2026. Auditing them tells you which links are still live, which have switched to nofollow (and stopped passing equity), which anchor texts are over-optimised, and which referring pages have died. Each finding has direct ranking and disavow implications.

What is the difference vs Ahrefs or Semrush?

Ahrefs and Semrush are deep historical backlink databases. They are great at finding links you did not know about, but their freshness lags the live web by days or weeks. This audit live-verifies the links those tools surface so you act on current data, not stale data.

What is the difference between dofollow, nofollow, UGC, and Sponsored?

Dofollow links pass PageRank equity and SEO value. Nofollow links do not pass equity but still drive referral traffic and brand signal. UGC marks user-generated content (forum, comment, profile links) and is treated as a soft nofollow. Sponsored marks paid links and must be declared to comply with Google's link spam policy.

Should I disavow nofollow links?

Generally no. Google already ignores nofollow links for ranking purposes, so disavowing them is wasted effort. Reserve your disavow file for clearly toxic dofollow links from spammy or penalty-hit domains. Use this audit to confirm a link is actually dofollow before disavowing it.

Does this audit estimate Domain Authority?

The free tier reports HTTP status, rel attribute, anchor, and live presence. SBMM Pro adds DA / DR estimation, referring-page topical relevance to your niche, multi-signal toxicity scoring, and an adaptive disavow recommendation.

How fresh is the backlink data?

It is as fresh as the moment you run the audit. Every URL in your batch is fetched live during the run, parsed once, and reported. There is no database between you and the live web, so the freshness is identical to a manual browser visit.

Can I audit a list of 10,000 backlinks?

Not on the free tier, which is capped at 100 links per run for fair-use reasons. For large lists, run multiple batches across days, or upgrade to SBMM Pro which lifts the cap. Most disavow and outreach workflows only need to audit a few hundred high-priority links anyway.

Will this tool submit a disavow file for me?

No. Disavow submission must be done manually through Google Search Console because it requires signed authentication that only you have. This audit gives you the cleaned, live-verified list you paste into the disavow.txt file before uploading it to Search Console yourself.
