Performance sanity-check
Use your average CPC & site conversion rate to estimate clicks & leads at either budget.
Formulas: Clicks = Budget ÷ CPC, Leads = Clicks × (CVR ÷ 100).
Typical budget scenarios
| Competitiveness | Monthly Budget | What to expect in 30–60 days |
|---|---|---|
| Niche / low CPC | $300–$1,000 | Directional data, a few conversions, slower learning. |
| Most local SMBs | $1,000–$3,000 | Reliable learnings, steady optimizations across keywords & ads. |
| Competitive metros / urgent scale | $3,000–$10,000+ | Faster learning, broader reach, room for testing (RSA, PMax). |
Your exact number depends on CPCs, geography, seasonality, landing page quality, and close rates.
How to use this tool (and your budget) effectively
- Pick a starting budget using revenue % or leads × CPL. Convert to daily by dividing by 30.4.
- Start with focused Search campaigns (Exact + Phrase), tight geo, strong negatives.
- Track primary conversions only (forms, qualified calls). Link GA4 & turn on enhanced conversions.
- Let it learn 2–4 weeks, then optimize search terms, RSAs, and bids. Scale when CPL is on target.
