Key Takeaways
- A monthly channel scorecard comparing CPL, qualification rate, and CPA across channels drives informed decisions.
- A/B test one variable at a time for 4-6 weeks (mail) or 2-4 weeks (digital) to achieve meaningful results.
- Quarterly budget reallocation shifts resources from high-CPA channels to low-CPA channels with scaling capacity.
- Reserve 10-15% of sourcing budget for testing new channels and campaign variations.
Optimizing sourcing channels requires ongoing measurement, testing, and reallocation of resources. This lesson provides step-by-step workflows for evaluating channel performance, running A/B tests, and systematically improving conversion rates at each funnel stage.
Building a Monthly Channel Scorecard
A channel scorecard tracks five key metrics for each sourcing channel on a monthly basis: lead volume, cost per lead, qualification rate, lead-to-close conversion, and cost per acquisition. By comparing these metrics across channels, you can identify which channels deserve more investment and which should be reduced or eliminated. The scorecard should also track trend lines—a channel with rising CPL and declining conversion may be experiencing market saturation. Record all data in a spreadsheet or dashboard that enables month-over-month comparison and trend analysis.
| Channel | Leads | CPL | Qual Rate | Close Rate | CPA |
|---|---|---|---|---|---|
| Direct Mail | 45 | $35 | 28% | 2.2% | $1,590 |
| PPC (Google) | 22 | $65 | 32% | 1.8% | $3,611 |
| Driving for $ | 18 | $8 | 40% | 3.3% | $242 |
| Cold Calling | 30 | $18 | 22% | 1.7% | $1,059 |
| Broker Network | 12 | $0 | 50% | 8.3% | $0 |
| Wholesalers | 8 | $0* | 62% | 12.5% | Fee-based |

A/B Testing Sourcing Campaigns
A/B testing involves running two variations of a campaign simultaneously to determine which performs better. For direct mail, test variables include letter vs. postcard, yellow letter vs. professional letter, different headlines, and different calls to action. For PPC, test ad copy, landing page design, and keyword targeting. For cold calling, test different scripts and opening lines. The key rule is to test only one variable at a time to isolate its impact. Run each test for a sufficient duration (typically 4-6 weeks for direct mail, 2-4 weeks for digital) to achieve statistical significance.
Budget Reallocation Workflow
Quarterly, review your channel scorecard trends and reallocate budget from underperforming channels to outperformers. The reallocation workflow follows four steps: First, rank channels by CPA (cost per closed deal). Second, identify channels with CPA more than 50% above your target—these are candidates for reduction or elimination. Third, identify channels with CPA below target and capacity to scale—these receive additional budget. Fourth, allocate 10-15% of budget to testing new channels or variations. This disciplined approach ensures continuous improvement while maintaining enough experimentation to discover new opportunities.
Case Study: Optimizing a Direct Mail Campaign
Your direct mail campaign has a 0.8% response rate and $45 CPL. You want to improve both metrics.
- 1Pull your current list criteria and compare against recent closed deals—are you targeting the right seller profile?
- 2A/B test letter format: send 500 yellow handwritten-style letters and 500 professional typed letters to matched segments.
- 3Track responses by mail piece variant using unique phone numbers or tracking codes.
- 4After 6 weeks, compare response rates. If yellow letters yield 1.2% vs. professional at 0.6%, adopt yellow letters.
- 5Next, test frequency: add a second touch (postcard) 3 weeks after the initial letter to a test group.
- 6Calculate new CPL and compare against control to verify improvement before scaling.
Response rate improved from 0.8% to 1.4% and CPL reduced from $45 to $28 through systematic A/B testing and list refinement.

Common Mistakes to Avoid
Running A/B tests with multiple variables changed simultaneously
Consequence: Impossible to isolate which variable caused the performance difference, leading to false conclusions
Correction: Test one variable at a time (headline, format, offer, list) while holding all other factors constant
Reallocating budget based on a single month of data
Consequence: Normal statistical variation gets misinterpreted as a trend, causing premature channel abandonment
Correction: Use quarterly reallocation cycles with monthly monitoring; require 3 months of consistent data before major budget shifts
