The fundamentals still matter — technical SEO, content quality, internal linking, authoritative backlinks. But three structural shifts have changed what 'ranking' means. One: Google AI Overviews now sit above the organic results on most informational queries, often answering the question without the user clicking through. Citation by AI Overviews is the new top-ranked position. Two: AI search engines (ChatGPT, Perplexity, Claude, Gemini) increasingly intercept queries before they reach Google. Brand mentions and authoritative citations across the web feed those models' answers. Three: Google's helpful content updates have made content depth and demonstrable expertise far more important — generic SEO content gets penalised, not just outranked.
Most agencies are still selling SEO as if it's 2018 — title tag optimisation, meta description rewrites, keyword density targets, link-building campaigns measured by domain authority. None of that is actively wrong, but none of it is sufficient. Topical authority through deep content clusters, structured data that AI models actually parse, and citation patterns that influence training data are the harder discipline.
We've spent the past two years specifically building SEO capability for this environment. Technical SEO is table stakes. AI search optimisation (AEO, GEO, LLMO) is where genuine differentiation now lives.
Done well, SEO remains one of the highest-ROI channels in a marketing stack — but the work has shifted.
