How the gate works
How the Lead Source ROI gate works
This tool grades each paid lead source on return and lead quality before you scale it. Every source gets its own verdict from where it lands on a grid of ROAS against qualified rate: ROAS against a 1x cut line and a 3x scale bar, qualified rate against a 20% floor. No verdict comes from a weighted score or a blend: the Dashboard reports a blended ROAS and a blended cost per qualified lead, but no verdict uses them, and the set gets no verdict. The fit gate can only make a source's verdict worse.
The 5 sources
1x, 3x and 20% are the workbook's default settings; you change all three on the Source Scorecard tab. A source exactly on a line counts as at or above it.
A source with ROAS at or above 3x can't read SCALE if fewer than 20% of its raw leads qualify: a strong return on cheap junk reads FIX until the fit improves.
Why: Facebook Ads returns 4.0x on $6,000 of spend, over the 3x scale bar, but only 96 of its 1,200 raw leads qualify. That 8% rate is under the 20% floor, so the fit gate holds it at FIX instead of SCALE.
A 4.0x return didn’t earn SCALE. Each source’s verdict comes from where its return and its fit land on the grid, one source at a time, and the fit gate reads the share of leads that qualify, not the revenue they happened to produce. Grades the lead-source numbers you enter - a planning tool, not financial or marketing-spend advice.
