Under the hood.
No black box.

The numbers update live as you type — this is exactly what the engine is doing with your four inputs.

01 · Funnel valueslead_value = value × conv% × lead%
= £750 × 50% × 25%
= £94
02 · Max CPAmax_cpa = lead_value × margin
= £94 × 60%
= £56
03 · Break-even ROASbreak_even = 1 / margin
= 1 / 0.60
= 167%

A lead, a conversation and a sale are not worth the same — and your bidding should know the difference.

To maximise ROI, you need to understand what each stage of your funnel is actually worth. Map the average value from lead through to sale, and you can make smarter decisions about how much to invest in acquisition — and feed those values straight into your ad platforms.

Value-based bidding.
Bid on worth, not volume.

Assign your funnel values to conversion actions in Google Ads and strategies like Maximise Conversion Value and Target ROAS stop chasing cheap conversions — and start chasing valuable ones.

Data compounds — bids get smarter every month

Prioritise high-value actions

On a limited budget, VBB targets the actions that lead to high-value conversions — a wedding enquiry form over a table booking — and nurtures them toward the sale.

Real-time optimisation

Google's AI adjusts bids on contextual signals like device, location and time of day — spending harder when the click is likely to be worth more.

Compounding benefits

The more value data you feed the algorithm, the sharper it gets — better performance now, and a stronger foundation for every month after.
