Rule-based scoring hits a ceiling fast
Point systems encode last year's assumptions. They can't notice that leads from a specific campaign at a specific hour close at triple the rate, because nobody thought to write that rule.
What you need to start
Less than people assume:
- A couple thousand historical leads with honest won/lost labels.
- Source, campaign, timing, and geography for each.
- Whatever the lead told you at intake — the form fields you already collect.
- A consistent definition of 'qualified' that everyone on the team uses.
Keeping it honest
Models drift. Markets shift, campaigns change, and a score that was accurate in March quietly degrades by August. Retrain on a schedule, monitor calibration against actual outcomes, and never let the score run unwatched.
Also watch for feedback loops: if reps only call high-scored leads, low scores never get a chance to prove the model wrong.
Why Global Advanta is the cutting-edge option
Our scoring runs on live CRM data and writes its reasoning to a log you can read, so a rep can see why a lead ranked where it did. And the score feeds your ad platforms as a conversion signal, so better routing also buys you better traffic.
Takeaway
Start with clean outcome labels, retrain on a schedule, and always leave a slice of low-scored leads worked so the model can be corrected.
