Lunchskins sells reusable and compostable bags as an alternative to single-use plastic, across retail and direct. The store has to explain the switch and cover a range of formats. My technical and SEO audit is below. Useful for a sustainable-swap product with several variants.

Site audit
88/100high7 of 10 sampled internal links are broken (4xx/5xx): /collections/ziptop-food-storage-bags, /products/compostable-food-wrap, /collections/paper-food-storage-bags…
Why Broken internal links dead-end shoppers and waste Google's crawl budget, chipping away at trust and indexing.
Fix Fix or redirect broken internal links — set up 301 redirects under Settings → Navigation / URL redirects, and check menu links after theme edits.
medium37 external scripts (heavy — hurts load time)
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 560 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 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.
medium4/13 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.
low2 H1 headings (use one)
Why The H1 tells Google and shoppers what the page is about. Missing or duplicate H1s blur that signal and weaken ranking.
Fix Use exactly one H1 per page — usually the product or page title. Fix duplicate H1s in the theme sections.
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.
low20 stylesheets (consider consolidating)
Why Minor performance hygiene. Small individual impact, but it adds up on a heavy page.
Fix Reduce the number of CSS files — many come from apps. Remove unused apps' leftover theme code and let your theme bundle its own styles.

Checkout and tracking
84/100highLegacy: legacy purchase/conversion dataLayer tracking
Why Legacy dataLayer purchase tracking depended on Additional Scripts running at checkout. That path is gone, so these conversions may no longer reach your ad platforms.
Fix Recreate purchase/conversion tracking as a Custom Pixel in Settings > Customer events so it fires on the new checkout with customer data intact.
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.
