What proper attribution can reveal after a year of real estate ad spend across channels
A small acquisitions operation buying single family homes in two metros spent 186,400 dollars in media plus 78,000 dollars in agency retainer over twelve months, with monthly channel-level cost per lead reporting that looked reasonable but told almost nothing about which channel actually produced closed deals. Building real attribution took about six weeks: a tracking number per campaign rather than per channel, a required source field at lead intake that could not be skipped, and a monthly reconciliation tying every closed file back to its originating lead. The hardest part was often not the new plumbing but cleaning up old data, since a source field can get overwritten when a lead is reassigned between departments, requiring months of history to be reconstructed from call recordings and email timestamps. A common result once this kind of tracking is in place: one channel, often search, takes a modest share of total media spend but produces most of the actual closings, at a cost per closed deal well under half of what a competing channel like social lead forms costs, even when social appears to take the largest single share of the budget. Once that gap is visible, the sensible move is trimming the underperforming channel to a small remarketing budget, shifting spend to what is working, and restructuring the agency fee toward performance rather than a flat retainer. Agencies rarely resist that restructure, which usually says they were waiting for a client to ask for it.
