Do it in order
Recommended Workflow
- 1
Find break-even first
Know your minimum ROAS before you judge any campaign. Above it is profit, below it is a leak.
- 2
Measure real CAC
Include every acquisition cost, not just ad spend, so the math is honest.
- 3
Cut waste before scaling
Add negative keywords and pause losers before you increase budget. Scaling waste just costs more.
- 4
Draft and test creative
Generate varied ad assets, then let performance, not opinion, pick the winners.

Metrics That Matter
- ROAS
- Revenue divided by ad spend. Useful only once you know your break-even point.
- Break-even ROAS
- Roughly 1 divided by your gross margin. The floor every campaign must clear to make money.
- CAC
- Total acquisition cost divided by new customers. Include fees, creative and tools, not just media.
- Ad-to-sales ratio
- Ad spend as a percentage of revenue. A quick read on efficiency across the whole account.
Avoid these
Common Mistakes
- Judging ROAS without knowing break-even, so profitable campaigns look bad and losers look fine.
- Counting only media spend in CAC and ignoring fees, tools and creative.
- Scaling budget before cleaning up wasted spend.
- Running one ad variant and never testing angles.
Questions
Category FAQs
Are these advertising tools free?
Yes. Every calculator and generator here is free with no sign up, and the optional AI brief is free too.
What is a good ROAS?
There is no universal number. A good ROAS is comfortably above your break-even ROAS, which depends on your margin. Calculate break-even first.
How do I calculate break-even ROAS?
Divide 1 by your gross margin. At a 50 percent margin, break-even ROAS is 2, meaning you need 2 dollars back for every dollar spent to break even.
Do the ad copy tools follow Google Ads limits?
Yes. The generator targets responsive search ad limits, up to 30 characters for headlines and 90 for descriptions, and checks for repetition.
Can AI manage my campaigns?
No. These tools model economics and draft assets. Bidding, budgets and final decisions stay with you.
