The product page is the most expensive real estate in your store. Most of you are wasting it.
I've been auditing Shopify stores for a while and keep seeing the same gap.
You pay $30-50 in ad spend to land a visitor on a product page. They scroll, read, maybe add to cart. Then they leave.
The block right under "Add to Cart" is empty. Or it's a generic "customers also viewed" carousel with 12 random products.
That spot is your highest-intent surface in the entire store. The visitor has already evaluated one product. Their wallet is half out. The cognitive cost of adding one more item is basically zero — but only if you make it easy.
What actually works there:
- 2-3 hand-picked complementary products (not algorithmic guesses)
- Variant already selected — no dropdown decisions
- One-tap add — no navigating to a new page
- Visible price + savings on the upsell
What doesn't work:
- "You might also like" carousels with 8+ products (paralysis)
- Cross-category recommendations (coffee + camo hat — why?)
- Recommendations that require leaving the current page to add
The stores I see doing this well are pulling 15-25% AOV lifts from this one block. The ones leaving it empty are basically lighting their ad spend on fire.
Curious what others have tested here. What's been your biggest lift on the PDP between Add to Cart and the fold?
