Background

André Sampaio is an SEO, AEO and GEO specialist based in Portugal. He builds organic visibility across Google and the AI platforms reshaping how people find information, including ChatGPT, Perplexity, Google AI Mode, and AI Overviews.

His work combines traditional SEO methodology with AI citation strategy, building organic visibility systems that perform across both established search engines and generative AI surfaces. The approach is grounded in semantic SEO, topical authority building, and data-backed content architecture.

His background spans search quality evaluation, digital marketing, and hands-on SEO. He focuses on organic growth that connects to revenue and business outcomes, not vanity metrics. More detail is on the about page.

Proven Track Record

André's documented case study is a 12-month engagement as the sole SEO specialist for Tee Times Golf Holidays, a 4,000+ page golf travel booking platform.

The work drove an estimated €100K in additional annual organic revenue, a conservative figure based on roughly 23,000 additional organic sessions year over year, a 0.7% conversion rate, and a €600 average order value. It grew ChatGPT referral traffic from 14 to 1,673 sessions, an 11,850% increase year over year, and established consistent citation across Google AI Overviews, AI Mode, and Perplexity.

The methodology included technical SEO remediation (resolving 249 duplicate URLs and crawl issues), a content architecture overhaul, entity clarification including a brand rename attribution fix, and AI crawler access configuration. This was a single engagement with measurable outcomes, documented in full on the portfolio and case study.

Availability and Focus

André is open to remote roles (in-house or contract), relocation for the right opportunity, freelance projects, and collaborations. The priority is work on organic growth that compounds: establishing visibility in AI-generated answers, building topical authority in competitive niches, and fixing technical foundations that hold back performance.

He works well in contexts such as:

• In-house SEO, AEO/GEO, or organic growth roles
• Teams with internal marketing capacity that need specialised organic growth expertise
• Brands with complex products or services that benefit from topical authority building
• Freelance or contract engagements in travel, tourism, SaaS, or professional services

For companies not hiring in-house, André also takes freelance engagements: organic visibility audits, strategy and roadmaps, and ongoing organic growth work. Details are in the areas of expertise section.

Methodology and Approach

• Semantic SEO framework. Topical authority built through comprehensive topic coverage, semantic content networks, and purposeful internal linking architecture.
• Content engineering. Scalable, repeatable content systems rather than one-off pages, including a Python pipeline that maps the semantic entity space for a topic to surface the entities, attributes, and relationships a page must cover.
• AI citation methodology. Content structured for LLM extractability using front-loaded answers, question-based heading hierarchy, entity-attribute-value coverage, and self-contained citable sections.
• Technical foundation. AI crawler access configuration (GPTBot, OAI-SearchBot, Google-Extended, Anthropic-AI, ClaudeBot, PerplexityBot, CCBot), JSON-LD structured data, and site architecture optimised for both search engines and LLM retrieval.
• Measurement. AI visibility tracking across platforms, citation frequency monitoring, and organic revenue attribution.

Tools and Projects

• GEO/AEO Topical Authority Tool (Python, agentic AI). An 11-step automated pipeline for AI search citation eligibility: SERP scraping, multi-model entity extraction, semantic map generation, validation against live SERP data, site crawl with rendering audit, gap analysis, and content brief delivery. Built with multi-model orchestration across three model tiers, a deterministic bias-override layer, state persistence with resume logic, and schema validation on every LLM response.
• SEO Arsenal + Watchtower (Python, GitHub Actions, SQLite). A private automation toolbox plus a scheduled observatory that collects rankings, competitor sitemap changes, and AI-surface citations weekly, and backlink snapshots monthly, committing all data to an append-only audit log. AI-citation checks run at $0 marginal API cost by reusing SERP data already collected.
• Content Engine (AI-assisted editorial pipeline). A five-stage production line: entity research, competitor gap analysis, content brief, writer, and quality assurance. Facts are classified stable or volatile before writing, every page must offer information gain over competing pages, and a QA gate with a two-revision limit quarantines anything that falls short for human review. Runs the editorial process behind Algarve Local Guide and adapts to any site through the arsenal's onboarding process.
• Algarve Local Guide (Astro, Node.js, Python, Preact). An independent travel guide to the Algarve, created from local knowledge and produced through the editorial pipeline above: six page types with build-time validation, a data pipeline producing JSONL feeds with semantic chunking and vector embeddings, and a client-side recommendation engine powered by a canonical entity database.
