My favourite question: when someone asks ChatGPT which brand to pick, why does yours come first, or not at all? I spend my days testing, measuring and taking generative engines apart on real sites.

My playground: classic search optimisation and brand visibility in the answers of ChatGPT, Perplexity, Gemini and AI Overviews. This journal is a personal project: I document my experiments, the wins, the misses, and what I learn from them.

What you will find here

• Measurement methods: prompt tracking, presence and outcome metrics, attribution.
• Experiments on real sites: what makes a brand show up in model answers, and what changes nothing.
• Honest write-ups: the wins as well as the misses, numbers included.
