Allbirds gets cited a lot as a clean Shopify build, and it holds up: fast product pages, a tight range, and sustainability messaging woven through the whole site instead of parked on one page. I ran a full audit and attached the results. If you sell a focused catalog, study how they keep the product pages simple.

Site audit
85/100highNo structured data (JSON-LD) found
Why Structured data is how search engines and AI understand your products. Without it you miss rich results and AI shopping visibility.
Fix Add Product, Organization, and BreadcrumbList JSON-LD. Many themes include it; a schema app fills gaps.
highNo Organization/merchant schema on the homepage (weakens brand entity for AI shopping)
Why AI shopping surfaces like Google AI Mode, ChatGPT, and Perplexity read price and availability from Offer schema. Without it your products can't show up there.
Fix Add Product, Organization, and BreadcrumbList JSON-LD. Many themes include it; a schema app fills gaps.
medium22 external scripts (on the heavy side)
Why Heavy pages load slower, and slower pages rank lower and convert worse. Speed is money on a storefront.
Fix Audit and remove apps you don't use — each adds scripts. Combine or defer non-critical ones.
mediumHTML document is 662 KB (large)
Why Heavy pages load slower, and slower pages rank lower and convert worse. Speed is money on a storefront.
Fix Trim the homepage: fewer sections, lazy-load below the fold, and remove unused app embeds.
mediumNo Product / Organization / WebSite schema
Why This schema powers breadcrumb and product rich results in Google. Without it your listings look plainer and get fewer clicks.
Fix Add Product, Organization, and BreadcrumbList JSON-LD. Many themes include it; a schema app fills gaps.
mediumNo BreadcrumbList schema (helps rich results)
Why This schema powers breadcrumb and product rich results in Google. Without it your listings look plainer and get fewer clicks.
Fix Add Product, Organization, and BreadcrumbList JSON-LD. Many themes include it; a schema app fills gaps.
medium16/42 images missing alt text (SEO + a11y)
Why Alt text is how search and screen readers understand images. Missing it loses image-search traffic and fails accessibility.
Fix Add descriptive alt text to product and content images in the theme editor / product media.
mediumFew modern image formats (WebP/AVIF) — larger downloads
Why Oversized, eagerly-loaded images are usually the biggest drag on Core Web Vitals, which Google uses for ranking.
Fix Serve WebP/AVIF — Shopify's CDN can, so re-upload large images or use an image-optimizer app.
mediumConsider testing urgency / social-proof on the homepage (none detected)
Why Social proof and urgency are among the biggest conversion levers. Without any, visitors have less reason to buy now.
Fix Add social proof and urgency (reviews, low-stock, countdowns). PopBoost does this without a theme edit.
lowWeak/absent cache-control on the document
Why Minor performance hygiene. Small individual impact, but it adds up on a heavy page.
Fix Set sensible cache headers on static assets; on Shopify this is handled by the CDN for theme assets.
AI shopping readiness
Point this at a product page for a full AI-shopping check.
Merchant Center risk
Needs a product page with product schema to assess risk.
Checkout and tracking
86/100mediumLegacy: Google Tag Manager container in the page
Why A GTM container that fed checkout tracking is exactly what the Additional Scripts lockdown broke. Purchase events routed through it can silently stop attributing revenue.
Fix Rebuild any checkout/purchase tags as a Custom Pixel via Settings > Customer events (Web Pixel API), or use the official channel apps. Don't rely on a GTM container for checkout events.
Check in your admin
- Settings > Checkout shows an "Upgrade" button. That means you're still on the legacy checkout. Unmigrated stores auto-revert to a default checkout by August 26, 2026 (August 13, 2026 for Plus).
- Any live Shopify Scripts (discounts, shipping, payment). Shopify Scripts stopped running on June 30, 2026. Rebuild that logic as Shopify Functions or your custom discount/shipping/bundle rules silently stopped working.
- The Additional Scripts field still has code in it. That field was locked August 28, 2025. Anything there no longer runs at checkout, so move it to Custom Pixels or official apps.
- Thank-you / order-status page customizations. Legacy order-status page edits don't carry over. Rebuild them as checkout UI extensions or post-purchase blocks.
- checkout.liquid customizations in your theme. checkout.liquid is deprecated and being removed. Move branding to the Checkout Editor and logic to UI extensions + Functions.
- Place a low-value test order after any tracking or checkout change. This is the one thing this checker can't do for you. We only see the storefront HTML, not what your ad platforms received. After any pixel, consent-banner, theme, or checkout change, buy something cheap and confirm the exact order value AND currency landed in GA4 and each ad platform. A pixel debugger showing an event firing does not prove the value and currency arrived correctly.
