What is VEO?
Voice engine optimization focuses on the voice assistants themselves (Alexa, Siri, Google Assistant and the voice modes of AI chatbots) and how they choose and present a single answer.
Each assistant pulls from different sources: search indexes, knowledge graphs, business listings and partner data. VEO makes sure your information is in those sources, correct, and phrased to be spoken.
Why VEO matters
Voice assistants answer with one result, often without a screen. Being the source an assistant trusts means being the brand it names.
How VEO works
- 01
Listen
The assistant converts speech to text and detects the intent.
- 02
Source
It queries its data sources, such as search, maps or partner databases.
- 03
Choose
It selects one answer, usually the most authoritative and concise.
- 04
Speak
It reads the answer aloud, sometimes naming the source.
VEO best practices
- Keep business listings on Google, Apple and Bing accurate and complete.
- Use speakable structured data on news-style summaries where it's supported.
- Write short, conversational answers that are easy to say aloud.
- Choose a brand name that's easy to pronounce and spell, and show how to say it if needed.
- Cover common spoken questions on your FAQ pages.

Aim for a passage that takes under about 30 seconds to speak, with the answer in the first sentence.
