How the Lead Source ROI Scorecard gate works
How the Lead Source ROI Scorecard grades one paid lead source: ROAS clears the 3x scale bar and the score lands at 82, but only 8% of raw leads qualify against a 20% floor — so the fit gate caps the verdict at FIX instead of SCALE.
How the gate works
This tool grades one paid lead source on return and lead quality before you scale it. Each control is marked from your own evidence and weighted into a 0–100 score — and then the score is run past a gate that can only make the verdict worse.
The 2 weighted controls
| Signal | Weight |
|---|---|
| ROAS strength | 70 |
| Qualified-lead fit | 30 |
| Total | 100 |
The verdict bands
A source with ROAS at or above 3x can't clear SCALE if fewer than 20% of its raw leads qualify - a strong return on cheap junk still caps at FIX until the fit improves.
In the worked sample it scores 82 out of 100 and still reads FIX — ROAS clears the 3x scale bar at 4.0x on $6,000 of spend, and the weighted score lands at 82 - comfortably inside SCALE range on paper. But only 96 of 1,200 raw leads qualify, an 8% rate well under the 20% floor, so the fit gate caps the verdict at FIX regardless of the score. Cheap junk that closes once in a while is still junk. The one thing to fix first: Qualified-lead fit - lift the qualified rate above 20% before scaling spend on this source..
Common questions
Can something score well on the How the Lead Source ROI gate works and still fail?
Yes. The weighted score is run past a worsen-only gate — the Qualified-rate floor gate — that can only make the verdict worse. In the worked sample it scores 82 out of 100 and still reads FIX, because rOAS clears the 3x scale bar at 4.0x on $6,000 of spend, and the weighted score lands at 82 - comfortably inside SCALE range on paper. But only 96 of 1,200 raw leads qualify, an 8% rate well under the 20% floor, so the fit gate caps the verdict at FIX regardless of the score. Cheap junk that closes once in a while is still junk.
What is a worsen-only gate?
A dispositive rule that can only lower a verdict, never raise it. One fatal flaw overrides an otherwise-good score, because a single disqualifying gap shouldn't hide behind a high average. The tool also names the one thing to fix first — here, "Qualified-lead fit - lift the qualified rate above 20% before scaling spend on this source.".
