What is NDCG?

Normalized Discounted Cumulative Gain

NDCG evaluates a ranking by considering relevance and giving more weight to higher positions. It is normalized so queries with different candidate sets can be compared.

What NDCG means in GEO

These metrics come from experimental evaluation. They help when reading GEO papers and designing more rigorous tests.

Why it matters

Define the relevance scale and ranking cutoff before comparing systems.

What to check in practice

Review the unit of analysis, sample, baseline, confidence interval and treatment of ties or missing items.

How it connects to other concepts

NDCG belongs to research metrics. It is best analyzed alongside related terms because AI visibility depends on several stages and signals rather than one isolated optimization.

Common mistake

Turning an improvement on a closed benchmark into a universal ranking promise for commercial products.
