A product page has one job: answer every question before the buyer has to ask.
1. One clear photo first
Show the product, big and sharp.
2. The price, and what's included
No surprises at checkout.
3. Delivery time in plain words
"Ships in 2 days" beats "fast shipping".
4. Real reviews
Even three honest reviews lift trust.
5. One obvious Buy button
Everything else is secondary.
