How to use Search Advertising Performance Calculator
- Use eligible impressions and a CTR measured on the same reporting basis.
- Enter post-click conversion rate and conversion value with a defined attribution window.
- Validate incrementality, refunds, lead quality, and gross margin before scaling spend.
Calculator guide
Understanding Search Advertising Performance Calculator
Search advertising performance has two connected stories: an impression-to-conversion funnel and a money bridge from spend to attributed gross profit. A strong ROAS can still produce weak contribution when margin is ignored.
Calculation method
How the calculation works
Move impressions through entered click-through and post-click conversion rates, calculate CPC and CPA, and connect attributed conversion value with margin and advertising contribution. Apply CTR to impressions, CVR to clicks, multiply conversions by average value, apply gross margin, and subtract ad spend from attributed gross profit.
Campaign diagnosis
Locate the constraint before changing bids
The same contribution result can arise from different funnel failures.
Worked situations
Practical examples
- 850,000 impressions at 3.2% CTR produce 27,200 modeled clicks.
- A 4.5% post-click conversion rate produces 1,224 conversions.
- Attributed revenue must be multiplied by margin before spend is subtracted to estimate contribution.
Better inputs
Useful tips
- Segment brand and non-brand search because intent and incrementality differ.
- Use conversion value net of cancellations or refunds when possible.
- Review search terms, auction position, landing pages, and offline conversion quality alongside ratios.
Before relying on the result
Limitations and common mistakes
- The model assumes constant CTR, CVR, order value, and margin.
- Auction dynamics, attribution error, incrementality, lag, repeat purchases, refunds, view-through effects, and capacity are excluded.
- Attributed contribution is not audited profit.
Reference
Key terms
- CTR
- Clicks divided by impressions.
- CVR
- Conversions divided by clicks.
- CPA
- Advertising spend divided by conversions.
- Contribution after ads
- Attributed gross profit minus 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
Is ROAS profit?
No. ROAS compares attributed revenue with ad spend and ignores product and operating costs.
Why calculate contribution after ads?
It introduces gross margin before subtracting advertising spend.
Can CTR and CVR be multiplied?
Yes, when CTR is clicks per impression and CVR is conversions per click.
Does attributed revenue prove incremental sales?
No. Controlled measurement is needed for a strong incremental claim.
