The 15 PPC Metrics to Track in 2025

CTR measures the percentage of users who click on your ad after seeing it. A higher CTR indicates compelling ad copy and relevance.

Benchmark for E-commerce: 4-6%.
How to Improve: Use action-oriented headlines and relevant keywords.

2. Quality Score

Google assigns a Quality Score based on ad relevance, landing page experience, and expected CTR. A higher score reduces your cost-per-click (CPC).

Average Quality Score: 7/10.
Pro Tip: Optimize landing pages and align ad copy with keywords.

3. Conversion Rate

Conversion Rate tracks the percentage of users who complete a desired action, such as making a purchase or signing up for a newsletter.

Benchmark: 2.35% average, but the top 25% achieve 5.31%.
How to Improve: Simplify checkout processes and use retargeting ads.

4. Cost-Per-Click (CPC)

CPC determines how much you pay per ad click. Balancing low CPC with high-quality traffic is key to profitability.

Industry Average: $1.16 for e-commerce.
Optimization Tip: Use negative keywords to exclude irrelevant traffic.

5. Cost-Per-Acquisition (CPA)

CPA measures the total cost of acquiring a customer through your ads. It’s one of the most critical metrics for e-commerce businesses.

Target CPA: 20-30% of your product margin.

Goal: Maintain an impression share of 60% or higher.
Improvement Tip: Increase bids or expand your budget for key campaigns.

8. Ad Relevance Score

Ad Relevance measures how closely your ad matches user intent. A high score improves your ad visibility and lowers CPC.

Best Practice: Use tightly themed ad groups with targeted keywords.

9. Average Order Value (AOV)

E-commerce Benchmark: $50-$200.
Tip: Offer bundles or free shipping on higher cart values.

LTV measures the total revenue a customer generates over their lifetime.

Why It’s Important: Guides decisions on acceptable CPA and ROAS.
