FAQ
How does the diff work?
Paste your previous backlink export and current export (CSV or JSON). The tool identifies backlinks present in both (kept), only in previous (lost), and only in current (new). The diff is computed by URL — case-insensitive, trailing slash normalized.
What input format does it accept?
CSV with header `url,anchor,source_domain,da,link_type` (any subset works) or JSON array of objects. Both previous and current panels accept the same format.
How is percentage change calculated?
New % = new_count / previous_total × 100. Lost % = lost_count / previous_total × 100. Net change = new_count − lost_count.
What extra features does this tool have compared to others?
(1) Diff calculation (new/lost/kept). (2) New backlinks list. (3) Lost backlinks list. (4) Kept backlinks list. (5) Stats (counts). (6) Percentage change. (7) CSV export. (8) Copy report.

Is my data sent anywhere?
No. All diffing runs locally. History is stored in localStorage on this device only.
