What Is "Share of Model Voice", and Why Does It Matter More Than Your Google Rank?

SEO professionals are increasingly talking about a new metric: "Share of Model Voice" — roughly, "your share of AI model responses." While traditional SEO measured where you ranked in Google results, this metric measures how often an AI assistant (ChatGPT, Perplexity, Google AI Overview) mentions or cites you when answering a question related to your market.

Why does this matter more than a Google ranking?

A Google ranking applies to one specific keyword. Share of Model Voice measures whether an AI assistant, when summarizing your market or giving a recommendation, mentions you at all in its answer — regardless of the exact keyword the user asked about. It's a much broader, harder-to-measure, but longer-term more important kind of visibility.

How can it be improved?

AI models prefer to cite pages that:

• Contain concrete, verifiable facts and numbers (not just marketing slogans)
• Have clean, structured markup (schema.org, clear heading hierarchy)
• Update regularly — a page untouched for 2 years is a less trustworthy source in an AI's eyes

What does this mean in practice for a small business?

You don't need new content every day — but what's up needs to be accurate, current, and clearly structured. This is exactly what our SEO & Content Marketing service is built on: not one-off articles, but ongoing, GEO-aware content upkeep.

Summary

Share of Model Voice is still measured by few today, but it's becoming more important. Those who start paying attention to it now gain an edge over those still optimizing only for Google rank.
