CTR (Click-Through Rate)

Click-through rate (CTR) measures how often a listing is clicked when it is shown in search results. Formula: clicks divided by impressions, times 100.

Example: an Amazon listing is shown 10,000 times in search results and clicked 250 times → CTR = 2.5 %.

Average CTR on Amazon ranges 0.3 %–0.5 % depending on category. Anything above 1 % is solid; anything above 2 % is a strong signal that title and main image are doing their job.

CTR is the single most important metric for the listing "header" because it maps directly to the combination of title + price + main image + reviews.
