Calculator guide
Understanding Search Advertising Funnel Calculator
Paid-search performance is a chain of distinct conversion events. This calculator preserves the click-to-landing gap, then carries visitors through lead and customer stages before connecting the funnel to spend, attributed revenue, gross margin, and contribution.
Calculation method
How the calculation works
Move the entered impression population through click, landing, lead, and customer rates, then reconcile spend, attributed revenue, ROAS, and gross contribution. Apply each entered rate only to the immediately preceding stage, multiply clicks by CPC for spend, multiply customers by revenue per customer, and subtract spend from attributed gross profit after applying margin.
Optimization order
Diagnose the constraint before increasing spend
The narrowest or least efficient boundary is usually more actionable than the headline ROAS.
Worked situations
Practical examples
- 250,000 impressions at 4.2% CTR produce 10,500 expected clicks.
- A 96% arrival rate produces fewer landing visitors than clicks and keeps tracking or load loss visible.
- ROAS can be positive while contribution after product margin and ad spend is weak.
Better inputs
Useful tips
- Reconcile platform clicks with analytics sessions before blaming the landing page.
- Segment brand and nonbrand search because intent and incrementality differ.
- Use contribution and qualified-customer quality alongside ROAS.
Before relying on the result
Limitations and common mistakes
- The model is deterministic and does not estimate confidence intervals, auction feedback, saturation, or causal incrementality.
- Attribution windows, assisted channels, repeat purchases, lead scoring, refunds, cancellations, and payment timing are excluded.
- Increasing spend does not guarantee the entered CPC or conversion rates remain constant.
Reference
Key terms
- CTR
- Clicks divided by impressions.
- Landing arrival rate
- Recorded landing visitors divided by ad clicks.
- Close rate
- Customers divided by leads.
- Contribution after ads
- Attributed revenue times gross margin, less advertising spend.
Important note
Calculated from the entered campaign values. Validate attribution, incrementality, lag, margin, and observed source data before making decisions.
Frequently asked questions
Why are visitors lower than clicks?
Not every click becomes a recorded landing visit because of abandonment, redirects, page failure, consent, or measurement differences.
Is ROAS the same as profit?
No. ROAS compares attributed revenue with ad spend and ignores product cost and other operating expenses.
Can spend be scaled using this result?
Only as a scenario; CPC, mix, and conversion rates can change as budget expands.
Why can contribution be negative with revenue?
Attributed gross profit after applying margin may be smaller than advertising spend.
