CTR

On Amazon, CTR helps sellers and advertisers measure the effectiveness of their ad creatives, targeting, and product relevance. A high CTR generally means your ad is resonating well with the audience.

Where CTR is used:

• Sponsored Products, Sponsored Brands, and Sponsored Display campaigns
• Brand storefronts and custom landing pages
• A/B testing for creatives or headlines

Why CTR matters:

• Indicates how relevant your product is for the keyword or audience
• Affects ad quality score and auction competitiveness
• Helps optimize campaigns by identifying strong or weak performers

💡 Example: If your ad was shown 10,000 times (impressions) and received 200 clicks, your CTR is 2%.

In short:
CTR = Click-through Rate - the percentage of people who click your Amazon ad after seeing it. It’s a critical performance metric for evaluating ad effectiveness.
