TG Barker | Markov SEO Consultant Serving London from Slough.

Gordon Barker has worked as an SEO consultant since 1997, long before Google came to dominate search. He has spent decades inside search ranking systems, watching them evolve from simple indexes into today’s AI-driven engines.

Based near London in Slough, TG Barker provides technical SEO consultancy focused on how Google actually evaluates websites. Rather than relying on keyword-only tactics, the work centres on structure, semantic relevance, and internal authority flow — aligning optimisation with modern, AI-driven search behaviour.

Search visibility is not accidental; it is engineered. Every SEO strategy is shaped around the market, the competition, and the way search systems behave today, with transparent methods and measurable outcomes.

Demystifying Google’s SEO — What Actually Drives Rankings

I work with businesses across London and the UK in competitive markets where search visibility cannot rely on guesswork. Rather than following short-lived trends, my work focuses on understanding how Google evaluates websites as connected systems — where structure, relevance, and authority interact.

As search continues to evolve with AI, this systems-based approach becomes increasingly important. By analysing internal relationships, semantic relevance, and authority flow, SEO decisions can be made with greater clarity and consistency.

Whether the goal is to strengthen local visibility, compete in a demanding niche, or improve the performance of an existing website, the focus remains the same: building stable foundations that support predictable, long-term progress.
