Site Speed Tune-Up

Clean up theme bloat and improve Core Web Vitals

Stores get slow through a mix of heavy apps, oversized images, leftover theme code, and poor loading behavior. This recipe audits what is slowing the site down and helps you remove the highest-impact bottlenecks first.

PROMPT

Run a performance audit on my [Shopify/WooCommerce] store at [URL]. Measure Core Web Vitals (LCP, CLS, INP) and PageSpeed score. Identify: (1) render-blocking scripts and the apps they belong to, (2) orphaned code from uninstalled apps, (3) unoptimized images, (4) unused CSS and JavaScript, and (5) font loading issues. Apply the low-risk fixes I approve — like lazy loading, orphaned code cleanup, and font loading improvements — then provide a before/after comparison and a list of higher-risk changes to review manually.

How It Works

Your Claw runs a performance audit on your store, looking for render-

blocking scripts, oversized images, unused CSS, orphaned app code, and

font-loading problems. Then it applies the low-risk fixes you approve and

leaves the higher-risk items as a review list.

What You Get

  • Performance audit against Core Web Vitals (LCP, CLS, INP)
  • Identification of heavy third-party scripts and leftover app code
  • Image lazy loading and basic image optimization opportunities
  • Font-loading recommendations
  • CSS/JavaScript cleanup opportunities
  • Before/after performance snapshots

Setup Steps

  1. Provide your store URL and theme access
  2. Record a baseline audit
  3. Review the findings and approve the fixes
  4. Apply low-risk changes to the theme
  5. Re-test and compare the results

Tips

  • Measure first or you will end up optimizing blindly
  • App uninstall does not always remove the code it injected
  • Image optimization is often the fastest visible win
  • Defer or remove non-critical JavaScript before chasing micro-optimizations
  • Re-run the audit after every major app or theme change
