Click-Through Rate (CTR)
The percentage of people who see a product listing in search results and click on it, calculated as (clicks ÷ impressions) × 100.
What is Click-Through Rate (CTR)?
For marketplace SEO, click-through rate is one of the most important metrics because algorithms on Amazon, Etsy, and Google use CTR as a signal of relevance — products that get clicked more often are ranked higher over time. Product photography is the primary driver of CTR in search results — the main product image is the first (and sometimes only) element buyers evaluate when deciding to click. A superior main image can double or triple CTR, compounding into dramatically improved search ranking.
E-Commerce Relevance
Main image quality is the #1 factor in marketplace CTR. A 1% improvement in CTR compounds into significant ranking gains over time — professional product photography is the highest-leverage CTR improvement available.
