I've built dozens of Shopify stores and the same issues come up every time. Here are the 5 biggest conversion killers I see:

1. Too many steps to checkout

Every extra click loses ~7% of buyers. If your checkout has more than 3 steps, you're leaving money on the table. Enable Shopify's one-page checkout immediately.

2. Slow product images

Uncompressed hero images above 500KB destroy your mobile load time. Compress everything, use WebP format, and lazy-load below the fold.

3. No social proof above the fold

Reviews, trust badges, and "X people bought this today" should be visible without scrolling. People don't buy what they don't trust.

4. Generic product descriptions

Copy-pasting from your supplier kills SEO and conversions. Write benefit-driven descriptions that speak to your customer's pain points, not feature lists.

5. Missing upsells and cross-sells

30% of e-commerce revenue comes from post-purchase and cart upsells. If you're not using apps like ReConvert or Zipify, you're literally giving away revenue.

Fix these 5 things and watch your conversion rate jump. If you want a store built to convert from day one, that's what we do at BuildStack.
