Click-Through Rate (CRT), Cost Per Click (CPC), Quality Score, and Conversion Rate
In digital advertising, metrics play a critical role in determining the success of a campaign. Four key performance indicators—Click-Through Rate (CRT), Cost Per Click (CPC), Quality Score, and Conversion Rate—affect how well an ad performs, how much it costs, and whether it achieves the intended business goals.
Understanding the relationship between these four metrics can help marketers fine-tune their campaigns for maximum efficiency and return on investment (ROI). This guide explores each metric in detail and provides practical strategies to optimize them.
Understanding CRT (Click-Through Rate)
What is CRT?
Click-Through Rate (CRT) is the percentage of users who click on an ad after seeing it. It indicates how appealing and relevant an ad is to its audience.
How CRT is Calculated?
CTR = (Total Clicks / Total Impression)*100
For example, if an ad receives 100 clicks out of 5,000 impressions, the CRT is 2%.
Importance of a High CRT in Advertising
- A higher CRT means greater engagement and relevance.
- It helps improve Quality Score, which can reduce CPC.
- High CRT can lead to better ad placements and increased conversions.
Ways to Improve CRT
- Use compelling ad copy and strong calls to action (CTA).
- Implement A/B testing to find the best-performing ads.
- Optimize headline and descriptions for relevance.
- Use relevant keywords that match user intent.

CPC (Cost Per Click) refers to the amount an advertiser pays for each click on their ad. It’s a crucial metric in PPC (Pay-Per-Click) advertising models like Google Ads and Facebook Ads.
