If I already have good SEO, do I really need GEO?

Strong SEO helps the web search layer of LLMs but does not guarantee visibility in the model's organic knowledge. There are brands ranked #1 on Google that are invisible when you ask an LLM directly. They are complementary disciplines, not substitutes.

Is GEO ranking as predictable as Google's?

No. LLMs are not deterministic — the same prompt can produce slightly different answers across runs. GEO analysis therefore requires aggregated multiple runs, unlike a fixed SERP position.

How long does it take to see results in GEO?

The web search layer can change in days or weeks because it depends on traditional SEO. The organic layer only changes on model retraining cycles, which can take months.
