SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Ads-math eliminates guesswork in PPC and CRO decision-making by turning messy performance inputs into clear, comparable profitability metrics so you can decide whether to scale, maintain, or cut.

Core Features & Use Cases

  • Core PPC unit economics: Computes CPA, ROAS, MER, and LTV:CAC from period spend, conversions, revenue, and customer economics.
  • Profitability guardrails: Runs break-even CPA/ROAS analysis from AOV and margin to reveal maximum profitable targets and headroom.
  • Scaling and opportunity sizing: Estimates impression-share budget/rank loss opportunities and builds budget forecasts with scenario planning.
  • Use case: If you paste a 30-day Meta/Google Ads export with spend, attributed revenue, and conversions, the skill calculates CPA/ROAS, flags whether you’re above break-even, projects outcomes for your next budget period, and summarizes what to do next.

Quick Start

Ask for PPC financial analysis by providing your ad spend, conversions, and (if available) attributed revenue, plus AOV and margin if you want break-even and scaling recommendations.

Frequently Asked Questions about ads-math

FAQPage Schema
How do I calculate PPC profitability from my ad spend and revenue data?▼

To calculate PPC profitability, you need to convert your period ad spend, conversions, and attributed revenue into CPA, ROAS, and MER metrics. This process reveals your unit economics and helps determine whether to scale, maintain, or cut your campaigns.

How do I find my break-even CPA and ROAS for paid search and social campaigns?▼

Finding your break-even CPA and ROAS requires applying your average order value (AOV) and profit margin to your marketing metrics. This analysis reveals your maximum profitable acquisition targets and shows how much scaling headroom you have before losing money.

Can I calculate LTV:CAC and marketing efficiency ratio without API access?▼

You can calculate LTV:CAC and marketing efficiency ratio without API access by pasting exported data from Meta or Google Ads. The system uses your provided spend, conversions, and customer economics values to compute the metrics directly.

What is the best way to forecast PPC budgets and impression-share opportunities?▼

The best way to forecast PPC budgets and impression-share opportunities is by analyzing past performance data to estimate rank loss potential. Scenario planning with your historical exports helps project outcomes and set accurate budget targets for your next planning periods.

Does this approach work for analyzing CRO scenarios and scaling headroom?▼

This approach works for CRO scenarios by translating conversion rate improvements into clear profitability metrics like CPA and ROAS. It assesses your scaling headroom by comparing current performance against break-even thresholds derived from your margins and AOV.
