ChatGPT, Google AI Overviews, Perplexity, Claude, Gemini — they all go by the name AI search engines, but they work fundamentally differently. A strategy that has impact on one platform isn’t automatically effective on another. This cluster makes the difference concrete.
Per platform you’ll learn how retrieval works, which signals carry the most weight, and which tactics have the most impact potential. This cluster closes with a consolidated overview across three dimensions: what has the highest chance of impact, the critical factor, and measurability.
→ Our prioritisation heuristic — a Groundbase judgement, not a market fact: for broad consumer reach, start with Google AI Overviews; for professional users, Perplexity is the most transparently measurable.
