Frequently asked questions
Where do I get the backlink data?
Export from Google Search Console, Ahrefs, Semrush, Majestic or any crawler, then paste the list here. This tool analyses and scores what you already own.
Does it crawl the web for live links?
No — by design it analyses the dataset you paste so it is free and instant. Pro connects to a live web index for continuous checking.
What counts as a toxic link?
A heuristic blend of irrelevant anchors, low-trust TLDs, spam patterns and extreme exact-match anchor concentration. Treat it as a triage signal, not a verdict.
Which CSV columns are supported?
source URL, target URL, anchor text and rel (dofollow/nofollow). Column names are auto-detected and mappable.
