Paste your canonical Name + Address + Phone. Then paste each listing version (Google Business, Yelp, Bing, Apple, BBB, Facebook). The tool diffs each, flagging spacing, abbreviation, and phone-format mismatches that hurt local rank.
Format: Listing name | Name | Phone | Address (pipe-separated). Examples: Google Business | Recovery Idaho LLC | 208-555-1234 | 123 Main St., Boise ID 83702. The tool diffs each listing against your canonical NAP and flags every mismatch.
