The Science of Search: Why Formulas are the Backbone of Google Ads
Behind every successful Google Ads campaign is a mountain of math. From the simple Click-Through Rate (CTR) to the complex variations of Ad Rank and Incremental Return on Ad Spend (iROAS), understanding these numbers is the difference between a profitable account and a money pit.
Our Interactive Google Ads Formula Trainer is designed to build "muscle memory" for performance marketers. Instead of reading a static list, you actively recall and verify your knowledge.
Interview Success
"What is the break-even ROAS for a product with a 40% margin?" If you can't answer this in 5 seconds, you might lose the job. Our tool ensures you are always ready.

Mastering the Metric Hierarchy
We categorize our 200 formulas into several key groups to help you specialize:
- Basic Metrics: CTR, CPC, CPM, Impressions.
- Conversion Math: CPA, CVR, Cost/All Conv.
- E-commerce Logic: ROAS, AOV, GMV, MER.
- Auction Dynamics: Ad Rank, Quality Score, Impression Share.
- Portfolio Strategy: Bid modifiers, Budget scaling, LTV.
Pro Tip: The MER Rule
"Don't get blinded by in-platform ROAS. Always calculate your Marketing Efficiency Ratio (Total Revenue / Total Marketing Spend) to understand the real impact of your Google Ads on the business ecosystem."
