Key PPC Metrics Explained
1. CTR (Click-Through Rate)
Formula: CTR = (Clicks ÷ Impressions) × 100
CTR measures how often people click your ad after seeing it. A high CTR means your ad is relevant and attractive to users.
Why It Matters: High CTR improves your Quality Score, lowers CPC, and boosts Ad Rank.
2. CPC (Cost Per Click)
Formula: CPC = Total Cost ÷ Total Clicks
It shows how much you pay each time someone clicks your ad. It can vary depending on competition, quality score, and bid strategy.
Why It Matters: Lower CPC means more traffic within your budget.
3. CPA (Cost Per Acquisition)
Formula: CPA = Total Cost ÷ Total Conversions
CPA tells you how much you’re spending to get a conversion like a sale or sign-up.
Why It Matters: It’s critical for ROI-focused campaigns.
4. ROAS (Return on Ad Spend)
Formula: ROAS = Revenue from Ads ÷ Cost of Ads
ROAS tells you how much revenue you earn for every dollar spent on ads.
Why It Matters: It helps measure profitability, especially for e-commerce.
A/B Testing Ads and Landing Pages
What is A/B Testing?
A/B testing compares two or more ad or landing page versions to find what works best for CTR, CPA, or ROAS.
