Key PPC Metrics: CTR, CPC, CPA, ROAS

1. CTR (Click-Through Rate)

  • Formula: (Clicks ÷ Impressions) × 100
  • Indicates how often people click your ad after seeing it.
  • High CTR means your ad is relevant and engaging.

Why It Matters: A high CTR can improve your Quality Score, lower your CPC, and increase your Ad Rank.

2. CPC (Cost Per Click)

  • Formula: Total Cost ÷ Total Clicks
  • Shows how much you pay every time someone clicks your ad.
  • Influenced by competition, bidding strategy, and Ad Rank.

Why It Matters: Lower CPC means more clicks for your budget, helping control ad spend effectively.

3. CPA (Cost Per Acquisition)

  • Formula: Total Cost ÷ Total Conversions
  • Reveals how much you’re paying per sale, lead, or signup.
  • Crucial for performance-focused campaigns.

Why It Matters: Helps assess whether your campaign is cost-efficient in driving real results.

4. ROAS (Return on Ad Spend)

  • Formula: Revenue ÷ Cost of Ads
  • Measures how much revenue you earn for every dollar spent on ads.
  • For example, ROAS of 5 means $5 return for every $1 spent.

Why It Matters: Especially important in ecommerce, ROAS guides decisions around profitability and scaling.

Pro Tip: Monitor all these metrics together. High CTR but low conversions may indicate weak landing pages, while low CTR with high ROAS can still be profitable.

A/B Testing Ads and Landing Pages

What is A/B Testing?

A/B testing, or split testing, compares two versions of an ad or landing page to see which performs better across metrics like CTR, conversion rate, CPA, or ROAS.

Why A/B Test?

  • Refine ad headlines and boost CTR
  • Optimize offers or layouts to increase conversions
  • Reduce your CPA or CPC over time
  • Base decisions on data, not guesswork

Ad Testing Ideas

  • Headlines: Try different CTAs or angles
  • Descriptions: Change tone or highlight benefits
  • Display Paths: Add keywords or categories
  • CTAs: “Buy Now” vs. “Start Free Trial”
  • Ad Extensions: Try various sitelinks or callouts

How to Run A/B Tests

Responsive Search Ads (RSAs):

  • Add multiple headlines and descriptions
  • Google auto-tests combinations

Manual Testing:

  • Create 2–3 variations in a single ad group
  • Monitor performance with equal budget

What to Measure

  • CTR, Conversion Rate, Quality Score, CPA, ROAS

Tip: Let your test run for at least two weeks with sufficient clicks before declaring a winner.

Landing Page Testing

What to Test:

  • Headline (tone, clarity, keyword)
  • CTA (button color, placement, wording)
  • Images or videos
  • Form length
  • Page structure and layout
  • Offer type (discount, free trial)

Testing Tools:

  • Unbounce, Instapage, Webflow
  • Google Ads Experiments

Key Metrics:

  • Conversion Rate
  • Bounce Rate
  • Time on Site
  • Page Load Speed

Best A/B Testing Practices

  • Test one element at a time
  • Collect enough data (100–300 clicks)
  • Run tests across different days/times
  • Keep track of learnings and wins

Budget Optimization

What is Budget Optimization?

It’s the process of allocating ad spend to maximize ROI by boosting top performers, cutting waste, and meeting campaign goals effectively.

Key Tactics

  • Set Clear Goals: Choose whether to focus on clicks, conversions, revenue, or impressions
  • Structure Campaigns: Organize by product, goal, or audience
  • Use Shared Budgets: Let Google distribute based on performance
  • Prioritize Performers: Shift budget to top campaigns and cut low ROI ones
  • Use Ad Scheduling: Focus budget on high-converting times
  • Geo Targeting: Invest more in top-performing regions
  • Leverage Smart Bidding: Use if you have sufficient conversion data
  • Monitor Limits: Avoid capping budgets on winning campaigns
  • Test and Reinvent: A/B test, then reinvest in what works
