www.celerion.com AI Visibility Analysis

Answer Engine Optimization (AEO) measures how often AI assistants cite your brand when answering real buyer questions. Unlike SEO, AEO isn't about ranking on a blue link — it's about being the answer.

A 28% score means, on average, www.celerion.com was mentioned in 28 out of every 100 relevant AI responses we tested. The industry benchmark for a well-optimized brand is 60% and up. Most brands score below 20% on their first audit.

The entity-presence checks above drive most of this score. LLMs are trained on — and cite from — Wikipedia, Wikidata, Bing, Brave, and the Google Knowledge Graph at disproportionate rates. Missing from one of those? You're likely missing from the answer.

How would your brand score?
