Cocofloss sells premium dental floss and oral care, taking a boring category and giving it real brand personality and subscriptions. That repositioning is the lesson. My technical and SEO audit is below. Useful if you sell an everyday consumable and want it to feel premium.

Site audit
85/100high7 of 10 sampled internal links are broken (4xx/5xx): /collections/labor-day-sale, /, /collections/new-arrivals…
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.
high15 third-party script hosts (app bloat slows the store)
Why Every third-party app script blocks the page from loading. App bloat is the top cause of slow Shopify stores, and speed drives both ranking and conversion.
Fix Uninstall unused apps and confirm they removed their theme code — that's the #1 Shopify speed fix.
mediumTitle is 86 chars (aim 30–60)
Fix Set a unique 30–60 char title per page in your theme's SEO settings (or Search & Discovery).
medium36 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 2152 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.
medium156/406 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.
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.
low17 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.

Merchant Center risk
Needs a product page with product schema to assess risk.
Checkout and tracking
78/100mediumLegacy: 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.
mediumKlaviyo detected, verify its checkout tracking moved to a Web Pixel
Why Email and marketing apps often used the Additional Scripts field to fire checkout and order events. That field is locked now, so any tracking they left there stopped working. Most have shipped a Web Pixel version, but old installs can still be on the broken path.
Fix Open the app and confirm its Shopify integration is on the Web Pixel / Customer events path, not the old Additional Scripts snippet. Update the app if it still asks you to paste code into Additional Scripts.
mediumYotpo detected, verify its checkout tracking moved to a Web Pixel
Why Email and marketing apps often used the Additional Scripts field to fire checkout and order events. That field is locked now, so any tracking they left there stopped working. Most have shipped a Web Pixel version, but old installs can still be on the broken path.
Fix Open the app and confirm its Shopify integration is on the Web Pixel / Customer events path, not the old Additional Scripts snippet. Update the app if it still asks you to paste code into Additional Scripts.
mediumRecharge detected, verify its checkout tracking moved to a Web Pixel
Why Email and marketing apps often used the Additional Scripts field to fire checkout and order events. That field is locked now, so any tracking they left there stopped working. Most have shipped a Web Pixel version, but old installs can still be on the broken path.
Fix Open the app and confirm its Shopify integration is on the Web Pixel / Customer events path, not the old Additional Scripts snippet. Update the app if it still asks you to paste code into Additional Scripts.
lowLegacy: other inline ad pixels (TikTok / Snap / Pinterest)
Why Inline TikTok/Snap/Pinterest pixels are the same legacy pattern. They need to move to the Web Pixel API or their official Shopify app or they lose checkout events.
Fix Add each ad platform via its official Shopify channel app or a Custom Pixel, then delete the inline snippet.
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.
