Technical SEO & E-Commerce Case Studies

Every project undergoes a rigorous diagnostic, targeted code implementation, and objective result measurement without extrapolation.

Technical SEO & Speed

Mobile Speed & Core Web Vitals on PrestaShop 8

Platform: PrestaShop 8.1 Sector: Fashion (France) Scope: Performance audit, template optimization & caching
🔍 Problem & Diagnostic

Excessive mobile load times (> 4.5s lab metric), degraded Largest Contentful Paint (LCP), and Core Web Vitals warnings in Google Search Console.

⚙️ Personal Role & Intervention

Child theme optimization, deferred non-critical JavaScript execution, WebP pipeline setup, and opcode cache tuning.

📈 Verified Result

Significant reduction in visual template rendering time and substantial improvement in synthetic lab performance benchmarks.

Indexing & Architecture

Resolving Crawl & De-indexing on PrestaShop 1.7

Platform: PrestaShop 1.7 Sector: Furniture & Decor Scope: Crawl audit, 301 redirect map & XML sitemaps
🔍 Problem & Diagnostic

Substantial catalog de-indexing following category restructuring, circular 301 loops, canonical conflicts, and faceted navigation bloat.

Redirect cleanup eliminating circular chains, canonical consolidation, faceted filter management (targeted noindex + robots.txt rules), and segmented XML sitemaps.

📈 Verified Result

Progressive resolution of critical crawl errors in Google Search Console and steady restoration of Googlebot crawl frequency.

E-Commerce Security

Emergency Store Decontamination & Hardening

Platform: PrestaShop 1.7 / cPanel Sector: B2B Distribution Scope: Emergency response & vulnerability hardening

Background & Software Engineering

My optimization methodology is grounded in a firm conviction: technical e-commerce SEO is a matter of disciplined software engineering, not speculative tricks. Holding a Master's degree in Information Systems Engineering (University of Poitiers) and a Master of Science in Management (University of Manchester), I approach online store performance through the dual perspective of source code architecture and business profitability.

Specialized in PrestaShop core architecture and internals, I intervene directly within controllers, Smarty/Twig templates, SQL queries, custom modules, and server-level hosting configurations. In strict alignment with Core Web Vitals criteria and Google Chrome Baseline standards, I build resilient, long-term solutions to clean up indexation, accelerate rendering, and secure transactional flows.
