Frequently asked questions

What is CTR?
Click-through rate (CTR) measures how many people clicked on your ad compared to the number who saw it. It's a quick snapshot of how well your ad is performing.
Why is CTR important?
High CTR means ads are landing. Low CTR points to weak main image, price, title, or targeting.
Can this help me lower ad costs?
Yes. Higher CTR signals relevance to Amazon's auction, lowering your Cost Per Click (CPC) on the same bid.
How often should I check my CTR?
Check CTR weekly. Pair with Brand Analytics and Search Query Performance (SQP) for query-level reads.
Is this tool free to use?
Yes. The CTR Calculator is free. No signup, no catch.
