The document discusses optimizing a business's Craigslist advertising strategy by analyzing their F.I.A.T. (Frequency, Area, Inventory, Time) status. It describes a case study that evaluated criteria like region, vehicle numbers and types to determine why some clients succeeded on Craigslist while others struggled. The F.I.A.T. factors are examined, particularly the importance of frequency of posting, location testing, and timing of ads. Calculations are provided showing how inventory levels and posting frequency can impact monthly Craigslist views. The key message is that properly applying the F.I.A.T. framework can increase sales by 10-30% by doing Craigslist advertising right.
