Amazon PPC glossary
Click-through rate (CTR)
Click-through rate (CTR) shows how often people who see your ad actually click it. A low CTR often means the main image, title or price is not catching attention for that search.
Example
Your ad was shown 2,000 times and got 10 clicks. 10 divided by 2,000 is 0.005, so your CTR is 0.5%.
Where it matters most: Book 1, The Amazon PPC Clarity Guide, in the chapter “Listing Optimization.”
