Findings by Category
Core Web Vitals
LCP high (~4.2s). INP/CLS acceptable. Unoptimised hero images and render-blocking scripts.
Page load speed
Homepage 4.1s, PDP 5.2s. Collection pages acceptable. Product page slowest.
Asset optimisation
Images not WebP, some unoptimised. Fonts could be subset. Defer non-critical JS.
Liquid & code quality
Modern Liquid. Minor redundant snippets. No security concerns.
Shopify 2.0 usage
Sections in use. Metafields underused. App blocks could reduce layout shifts.
Mobile experience
Layout responsive. Tap targets fine. Checkout flow good on mobile.
Meta tags & schema
Missing product schema on PDPs. Titles/descriptions mostly present.
URLs & redirects
Redirect chains on legacy URLs. Canonical tags present.
Indexability
Robots.txt OK. Sitemap present.
Checkout flow
Mostly smooth. Trust signals visible.
Trust & credibility
Reviews visible. Policies linked.
App bloat
Some layout shift from apps on mobile.
Next Steps & Priorities
Defer blocking scripts and add lazy-load to eligible images (Optimise).
Fix redirect chains; add product JSON-LD schema to PDPs.
Glossary
Technical terms explained. Click any term to expand.
Core Web Vitals
Google's metrics for page experience: loading speed (LCP), responsiveness (INP), and visual stability (CLS).
LCP
Largest Contentful Paint — how long until the main content loads.
INP
Interaction to Next Paint, how quickly the page visibly responds after a tap, click or key press. INP replaced FID as a Core Web Vital in March 2024.
CLS
Cumulative Layout Shift — how much content jumps around while loading.
Liquid
Shopify's template language. Used to build themes and control what appears on each page.
Metafields
Extra custom data you can add to products, collections, etc. (e.g. fabric care, size charts).
App blocks
Shopify 2.0 feature — apps can inject content into theme sections without editing code.
Meta tags
HTML that describes the page (title, description) for search engines and social sharing.
Schema
Structured data that tells search engines what the page is about (e.g. product, recipe).
Structured data
Machine-readable info (JSON-LD) that helps search engines display rich results.
Redirect chains
Multiple redirects in a row (A → B → C). Can slow down users and dilute SEO.
Canonical
The "main" URL for a page when duplicates exist. Tells search engines which to index.
Crawl budget
How often and how much of your site a search engine will crawl. Matters for large stores.
Layout shifts
Content moving around as the page loads. Bad for UX and Core Web Vitals.
