Lustmia

1. Challenge

A Miami-based e-commerce storefront selling pre-owned luxury goods was underperforming on Google due to poor Core Web Vitals, incomplete SEO metadata, and a third-party app embed silently degrading page performance.

2. Business Requirements

• Improve organic search visibility through complete, accurate SEO metadata.
• Bring Core Web Vitals and Lighthouse performance scores into an acceptable range.
• Eliminate any third-party script posing a security or supply-chain risk.

3. Proposed Architecture

Worked within the existing Shopify theme and app ecosystem rather than a platform migration — auditing installed app embeds, theme scripts, and product/vendor metadata to isolate root causes instead of introducing new infrastructure.

4. Implementation Approach

Used Lighthouse audits to prioritize the highest-impact fixes first: removed the underperforming app embed, corrected metadata across 49 products, then removed a lookalike-domain script flagged as a supply-chain risk.

5. Security Considerations

Identified and removed a script loading from a lookalike domain — a supply-chain risk vector on e-commerce storefronts — as part of the remediation.

6. Results

Lighthouse SEO 92 → 100, Accessibility → 100, Performance improved from the high 30s to 79+ across remediation passes.
