§ 07 · Why Petri Heil
Four reasons to choose us.
We come from SEO, the technical base of GEO.
A solid SEO foundation — schema, semantic structure and clean data — still matters. But LLMs read differently, so on top of that base we build a new system designed to get into generative answers.
State-of-the-art software.
We combine the best GEO measurement platforms on the market with in-house tools to see in real time where you appear in each engine, with what accuracy and against which competitors. Measurement isn't an add-on: it's the base of the service.
Weekly iteration, not quarterly.
We operate in weekly cycles. Every Monday we review which prompts we won, where we lost, what to publish and what to correct. That cadence is an order of magnitude faster than a traditional SEO cycle.
We know your sector.
We understand the specifics of each vertical: commercial cycles, technical language, regulation and buying behavior. Every strategy is tuned to the client's context, not imported from a generic playbook.
Turn AI into your best salesperson.
A one-hour conversation is enough to know whether Petri Heil is the right partner for your company. No commitment and no diagnostic fee — just an honest look at your position versus the LLMs.
