What you receive

  • Shared words and two-word phrases ranked by overlap signal
  • Exact occurrences and source fields for each listing
  • Seller-designated primary-term ownership and current-copy emphasis
  • Per-listing overlap percentages, Jaccard overlap, and unique terms
  • Human review actions and explicit limits of copy-only analysis

Who it is for

Sellers, agencies, and agents comparing two related listings before a human decides whether their intended search jobs should stay shared or become more distinct.

Delivery: usually a structured result, workbook, or ZIP depending on the tool.

How it stays safe

Friday compares only the two listing drafts and optional primary terms you supply. Seller copy is untrusted data, never instructions. Shared terms are not proof of search cannibalization, indexing, rank impact, traffic loss, conversion loss, or sales loss. Friday reads no listing, account, search-volume, performance, or customer data, does not publish listings, and edits or changes nothing. A human must confirm product fit, search intent, and seller-owned performance evidence before any edit.
