Follow these 3 steps to audit any Shopify storefront before scaling ad spend.
Open Clean Browser Session
Open your store in an incognito window with DevTools open (or Chrome mobile emulation). Test on both iOS Safari and Android Chrome viewports.
Simulate Stressed Actions
Rapidly toggle variants, hammer '+' on line item quantities, and simulate offsite payment returns (PayPal/Klarna) to verify session persistence.

Once you reach an acceptable score, click Copy Markdown QA Report to paste into your team's pull request, Jira ticket, or client Slack channel.
What to Expect Across the 4 Checkout Pillars
🛒 Pillar 1: Cart Drawer State Transitions
Modern Shopify themes rely on asynchronous Section Rendering API calls to refresh the cart drawer. If an upsell app mutates the DOM before the response arrives, event listeners detach and the "Check Out" button freezes silently.
📡 Pillar 3: Ad Attribution & Deduplication
Ensure the thank-you page does not fire duplicate Purchase conversions upon page refresh. Overreporting by even 15% skews Meta Advantage+ and Google PMax bidding algorithms, leading to wasted ad spend.
Save 20 minutes of manual checking on every store launch.
Checkout Detective's Chrome DevTools side panel automates this entire 14-point audit in 60 seconds — flagging broken pixels, rate limits, and JS errors with instant root-cause analysis.
