Arnaud Alexandre Castellon

Web consultant specializing in technical SEO, site architecture, and WordPress.

I focus on the design and optimization of websites with an approach oriented towards algorithmic understanding (Google) and real-world performance (traffic + conversion).

My work is based on three main pillars:

– SEO & Semantic Architecture

Structuring sites according to cocoon or silo logic (including circular silo), building optimized internal linking, page hierarchy, and PageRank flow management.

Using advanced methods like the 5 semantic lists to cover the entire lexical field and strengthen topical authority

– Content Strategy & SEO Scaling

Defining editorial strategies based on Search Console data (organic level, volumes, intents), applying the avalanche theory for progressive and controlled traffic growth

Producing and structuring content oriented towards search intent (informational → transactional)

– Technical SEO & Performance

Optimizing Core Web Vitals (LCP, CLS), managing assets (images, fonts), cache configuration, removing bloat, improving rendering and loading time

Working on HTML structure (Hn tags, semantics, accessibility) and overall DOM consistency

In parallel, I work on technical copywriting, particularly translating complex topics (health, bodywork methods, professional expertise) into understandable and SEO-exploitable content.

Main Stack:

WordPress

Google Search Console / GA4 / GTM

SEO Data (keyword analysis, intents, SERP)

Goal: to design clean, scalable sites that are understandable by Google and capable of generating qualified traffic.
