The Shopify product page checklist for 2026: 20 checks, top to bottom

Open your best-selling product on a phone. Work down the page with the list. Mark each check pass or fail. Fix the fails on the template, so every product gets the fix at once. The checks are practice from store audits. They are no guarantee of any result. Measure before and after.

Above the fold

1. 1Price is visible without scrolling on a phone.
2. 2Star rating and review count sit under the title and link to the reviews.
3. 3The main image shows the product clearly, on a plain background.
4. 4Variant choices show as swatches or buttons, with nothing hidden in a dropdown.

Proof

1. 1Customer photos sit near the variant picker, with products tagged.
2. 2Fit details such as height and size appear in captions where customers gave them.
3. 3Reviews show low ratings too. Hiding them is banned in the US and UK.
4. 4Video shows the product moving, folding or in use, if it does any of those.

Details

1. 1A size guide uses your own measurements. Check them against the real garment.
2. 2Materials and care sit in a short, scannable list.
3. 3The top three questions from support are answered on the page.
4. 4Related products suggest an add-on, such as a case or a refill.

Buy box

1. 1A delivery estimate appears as a date range near the button.
2. 2The returns policy is one line with a link, near the button.
3. 3The free shipping threshold shows how far the cart is from it.
4. 4Add to cart stays reachable on a phone. Long pages need a sticky bar.

Speed

Google's Core Web Vitals set three targets for a good page. Test your product template in PageSpeed Insights, on mobile. Then test again with each app switched off. The gap is that app's cost.

1. 1LCP: the main image loads first and is not lazy-loaded.
2. 2INP: variant and add to cart respond at once on a mid-range phone.
3. 3CLS: reviews and galleries reserve their space, so nothing jumps.
4. 4Leftover code: uninstalled apps left no snippets in the theme.

Why the last screen matters

Baymard Institute's running average puts cart abandonment near 70%. Extra costs and slow delivery are among its top reasons. A product page can answer both. Answering them before the cart costs only layout work.

Where Idukki fits (ours)

We make Idukki. It covers the proof section: customer photos and video, tagged to the cart, near the picker. Its galleries reserve their space as they load.
