FAQ
How does the gap analysis work?
Paste your backlinks and up to 3 competitors' backlinks (CSV or JSON). The tool finds domains linking to competitors but not to you, scores each opportunity by DA and the number of competitors linking to it, and sorts the best opportunities to the top.
How is opportunity score calculated?
Each gap backlink gets a score 0-100: base = DA × 0.6, plus 20 if 2 competitors link to it, plus 30 if all 3 link to it (consensus = stronger signal). The score helps prioritize outreach targets.
What input format does it accept?
CSV with header `url,anchor,source_domain,da,link_type` (or any subset) or JSON array of objects. Each competitor gets its own panel.
